Phase 5 WSI just introduced a new Mini Hand Stop. The new Mini Hand Stop comes in an MLOK model and a Direct Thread model. The direct thread model works with the Phase 5 LPSN handguards or any rail that has #10-32 tpi threaded holes that are 1.576 in. apart (such as the Centurion Arms CMR or KAC URX3.1, etc). Each model is available in Grey, Black or Red.

Phase 5 WSI also has both Direct Thread and MLOK versions here: https://phase5wsi.com

Phase 5 Weapon Systems Inc, (Phase5WSI) introduced a few new products this year at SHOT Show 2017 but the one that really stood out the most was this awesome new AR buttstock called the UMS or Universal Mini Stock. The Universal Mini Stock is an ultra compact al metal stock that can be attached to virtually any buffer tube out there including standard carbine buffer tubes and many AR Pistol buffer tubes. This could come in really handy for guys running an AR Pistol buffer tube on their AR Pistol while waiting for the tax stamp to come in. Once their stamp comes in and the AR is registered as an SBR you can just add the UMS on instead of needing to remove the pistol buffer tube and install a carbine buffer tube that accepts a stock. Sounds like these are a couple months away from being available for purchase. Check out the video and picture below.

Phase5WSI UMS Universal Mini Stock SHOT Show 2017

Pretty sure I have a QD End Plate on just about every rifle I’ve ever built but they all require you to get your big (sometimes gloved) hands into this tiny area to attach/detach the QD sling swivel. The new Sloped Quick Disconnect End Plate (SQD-EP) addresses that issue and gives you a nice ambi QD sling mount. It also covers up some of the castle nut for a cleaner look. I will definitely pick one of these up for my next build and see how it goes. Looks like a great design. Read more about it and check out the pics below.

 P5T SQD-EPP5T SQD-EP 3

The Phase 5 Sloped Quick Disconnect End Plate (SQD-EP) was designed to replace the standard AR15/M4 carbine end plate. While still meeting the requirements of the original design, the SQD-EP is lighter and QD Swivel compatible.

PROUDLY MADE IN THE USA FROM USA RAW BILLET 7075-T6 ALUMINUM.

– Compatible with mil-spec carbine reciever extensions, commercial-spec reciever extensions, and all Phase 5 Pistol Buffer Tubes on nearly all AR15/M4/.308 AR Variant lower recievers.
– Lightweight and sturdy 7075-T6 billet aluminum construction is about 80% stronger than 6061-T6 aluminum.
– Uses a standard AR15/M4 carbine Lower reciever extension castle nut (not included).
– Accepts all push button QD swivels and QD slings.
– QD mount is at a 30 Degree angle from the lower reciever to allow a 360 Degree rotation for ambidextrious use.
– Lighter than the standard stamped steel reciever extention end plate (0.39 oz vs 0.48 oz.

The SQD-EP is in-stock and shipping now. Normally I would just link to the manufacturer  (Phase5WSI.com) for new product announcements but I also just noticed that these are available at an intro price at www.RainierArms.com now through 9/15/16. 

Phase 5 Weapon Systems just introduced their new 15″ Lo-Pro Slope Nose M-LOK rail. This version is different from their other rails by removing all but the very front portion of the 12 o’clock picatinny rail as well as completely removing the short picatinny rail sections at 3, 6 and 9 o’clock and replaced them with a full run of M-LOK attachment slots. You can read more about the new Phase 5 Weapon Systems LPSN M-LOK rail below.

The 15″ LO-PRO SLOPE NOSE M-LOK Free Float Quad Rail was developed to accommodate the features of our 7.5″ LPSN quad rail to a longer 15″ version. The LPSN15 M-LOK was inspired by beneficial features that shooters have requested and demanded from us and other manufacturers.

Phase 5 LPSN MLOK rail 2

M-LOK is a modular locking accessory mounting system that is a direct attachment method for hard mounting accessories to a negative space mounting point. Designed by Magpul Industries as an evolution of the MOE® slot system used since 2007.

The slender light weight design, longer nose, ease of installation and superior construction and finish quality are some of the features that we designed into this system.

The LPSN15 M-LOK undergoes a rigorous extra de-burring process in order to ensure a smoother snag free finish. The details and level of care during the manufacturing of the LPSN15 M-LOK makes it the perfect choice for your AR-15 rifle build.

Phase 5 LPSN MLOK rail 1

TRUE-FIT TECHNOLOGY UTILIZED WITH THE LPSN15 M-LOK. Phase 5’s True-fit™ technology was developed to secure the rail system onto the barrel nut with an accurate and solid full contact method around the entire surface area. The Phase 5 Weapon Systems Inc. True-fit™ rail attachment system gives the operator peace of mind and confidence that the system will not move or come loose. This is accomplished with 6 screws that form the rail with our True Fit feature around the barrel nut without distorting or pinching the rail at the bottom like in other rails on the market. Phase 5’s True-fit™ rail attachment system allows for the repeated removal and reinstallation of the rail without fatigue.

Overall Length:15 inches

Inner Diameter: 1.350”

The new LPSN M-LOK rail can be purchased at www.Phase5WSI.com.

Phase 5 Weapon Systems recently completed their lineup of FATman and littleBOY Hex Brakes with the addition of the 9mm/7.62×39/6.8 model for both FATman (dual chamber) and littleBOY (single chamber) brakes with 1/2×36 threads. This now brings the total to 6 different muzzle brakes in the Hex Brake series including the 5.56/.223 with 1/2×28 threads & 7.62×51/.308/300BLK with 5/8×24 threads for FATman and littleBOY models as well. 

Phase 5 littleBOY and FATman Hex Brakes

Phase 5 littleBOY and FATman Hex Brakes 1**Not my photo but shows the size of these beasts.**

I have all except for the 9mm model right now and they are actually a very cool muzzle brake. They are on the larger side but at the same time they have a collar that covers a bit of the end of the barrel as you thread them on. They have a pretty stout look too. These are definitely work taking a look at if you’re in the market for a new muzzle device.

www.Phase5WSI.com

Phase 5 Weapon Systems has recently introduced a couple of really cool looking new Hex shaped muzzle brakes. The first was the FATman Hex Brake which utilizes a two chamber design to reduce felt recoil and 12 o’clock ports to compensate for muzzle rise. The newest version is the littleBOY Hex Brake and, as I’m sure you’ve guess already, is a little bit more compact (shorter) than the FATman. Currently both Brakes are available for 556/.223 and 7.62×51/.308/300blk but my contacts at P5WS have told me they will be releasing 9mm, 7.62×39 and 6.8mm versions later this month. Check out these sweet looking muzzle brakes and read the info below. Will make sure we let you know when the additional caliber options are available in a few weeks.

Phase 5 FATman Hex Brake 2

FATman Hex Brake

The FATman Hex Brake was created to solve issues faced by many competition shooters and precision rifle builders. The 2 large (FAT) ventilated baffle sections and chambers create the compensation needed to reduce the overall recoil felt by the shooter.

Phase 5 FATman Hex Brake 2

The FATman Hex Brake includes two top ports machined at a 20 Deg. forward directed angle. These top ports help direct the energy of the spent gas in a manner that maintains a flat consecutive result shot after shot. The design of the FATman Hex Brake allows the first chamber wall to sit as close to the barrel crown plane as possible. This design element was included to maintain the full accuracy of the barrel.

littleBOY Hex Brake

Introducing the littleBOY Hex Brake; a younger, compact version of the original FATman Hex Brake, which was also created to solve issues faced by many competition shooters and precision rifle builders.

Phase 5 littleBOY Hex Brake 2

Including 1 large (FAT) ventilated baffle section and chamber to create the compensation needed to reduce the overall recoil felt by the shooter. Just like its big brother, the design of the littleBOY Hex Brake allows the chamber wall to sit as close to the barrel crown plane as possible. This design element was included to maintain the full accuracy of the barrel.

The iconic Phase 5 Hex design gives the FATman and littleBOY Hex Brakes the perfect styling that custom gun builders are looking for.

I’ve been so busy lately that I’ve not had a ton of time to go to the range but last week I specifically made time to hit the range and function test my 7.62×39 AR Pistol I built. This thing had been sitting in my HSP INCOG Rifle Bag completely ready to go just begging for some action and it was my pleasure to oblige. Below you’ll see some pics of my 7.62×39 AR Pistol. I’ll first cover the components I used to build it and the range report will follow after that.

KAK Ind 762x39 AR Pistol Build 7

Basically all you need to retrofit or build any AR upper as a 7.62×39 is the Barrel, Bolt and Mags and KAK Industry has everything you need in one place. I already had an extra AR Pistol lower built so I just needed some of their awesome upper components. The lower is a Noveske N4 forged lower with an ALG Defense ACT trigger, Battle Arms Development Selector, Magpul MOE K2 grip, Law Tactical Gen3 Folding Stock Adapter, Phase 5 Weapon Systems Pistol Buffer Tube and a Sig Sauer SB-15 Arm Brace. I upgraded to a Wolf High Power Hammer Spring but probably could have done without it. 

KAK Ind 762x39 AR Pistol Build 7

KAK Ind 762x39 AR Pistol Build 7

For the upper I sourced the heart of the build at KAK Industry. They make all of their own components and have a great reputation. I used the KAK Industry 11″ 7.62×39 barrel, KAK Industry 7.62×39 complete BCG, KAK Industry Gas Block and Gas Tube. The upper receiver is an AERO Precision forged upper with a Northtech Defense Ti-FANG Titanium forward assist, Fortis Mfg Hammer charging handle, Centurion Arms 11″ CMR rail and a BattleComp BABC. Topped it all off with a Vortex Optics Viper PST 1-4 scope and an American Defense Mfg QD mount.

KAK Ind 762x39 AR Pistol Build 7

Of course the weather is changing up here in Michigan. It was cold and rainy that morning at the range but I couldn’t care less. I brought along some really nice Hornady 123gr 7.62×39 SST ammo to run through the brand new AR Pistol. The best thing you can do when function testing a new AR is to take it slow. I only had one ASC 7.62×39 mag so I loaded one round in the mag, pulled back on the charging handle, flipped the selector to “America” and pulled the trigger. As expected it went BOOM so I checked the chamber to make sure the rifle ejected the spent casing, which it did. After that first round goes as planned you get a bit of a smile on your face and start to have fun.

KAK Ind 762x39 AR Pistol Build 7

I loaded up another 5 rounds and proceeded to fire them down range sighting in the Vortex Optics Viper PST 1-4 scope.  First 3 rounds went through perfect but on the fourth I had a Failure To Feed. Keep in mind I only had 5 rounds in the mag to start meaning this was the second to last round in the mag. I stripped the mag, removed the round and inspected it noticing that once the mag was removed the round didn’t really seem to be stuck or anything. I loaded another 10 rounds and again, second to last round FTF. This was a recurring theme and it became very clear that the issue was with the mag and definitely not at all a problem with the Upper, BCG or Barrel. Other than the second to last round of each mag issue I had absolutely ZERO malfunctions with this build. It really was a pleasure to shoot. I’ve heard the ASC mags get better as you wear them in but I will also be looking into some other brands and will do a followup article specifically regarding 7.62×39 AR Mags.

KAK Ind 762x39 AR Pistol Build 7

So after blowing through almost all of my ammo getting to know the 7.62×39 AR Pistol, I saved the last 5 rounds to get a little grouping on paper. Now keep in mind, when I test fire my AR’s I always go to the shorter range. Its basically a 30-35 yard range that typically has less people on it. When I shoot for groups I usually head on over to the 100 yard range but being that this is just an AR Pistol, I had no bipod, etc I decided to stay on the shorter range and just get a group there. The image below shows you a 5 round group, just resting the handguard on a block. I’m positive I could tighten this group up but I was out of ammo. One of these days I’ll get it out on the 100 yard range and get some longer range data. I was very happy with this group though based on the distance I would expect to shoot this rifle at in a real world situation. 

KAK Ind 762x39 AR Pistol Build 7

Overall, I am very pleased with this build. Aside from the magazine issue, all of the parts functioned flawlessly. KAK Industry really is a one stop shop for tons of AR Parts including 5.56, 300BLK, 7.62×39, 458 SOCOM and .308 builds. This is not my first experience with KAK Industry and I’ve enjoyed every part I’ve purchased from them. For this specific build you can check out the KAK 7.62×39 AR Parts here. For all other builds just visit the KAKIndustry.com website and get to looking around at the awesome stuff they offer.  

I recently built a new sexy looking AR Pistol that I’ve been taking pictures of and have gotten quite a few questions about what components I used, why I set it up the way I did and how its running so far. Its been a while since I did a “Build Details” article so I figured since so many people were interested in this build I would do one on it. This article will basically be a run down of the different components as well as an explanation of why I used them if needed.

We’ve all seen some AR Pistols that have extremely short barrels/uppers. I tend to not go shorter than a 10.5″ barrel on mine as it’s short enough to make them more compact without sacrificing a ton of accuracy or velocity. This whole build started out with a mid length AERO Precision COP Upper and Forged Lower. This is the second AR I’ve built with this receiver set and I love them.

THE AR PISTOL UPPER
The Upper, as I mentioned, features an AERO Precision COP mid length upper with a Parallax Tactical TiN BCG, Magpul MBUS Pro sights and Fortis Mfg Hammer charging handle. For the optic I wanted something very small and compact so I went with the Vortex Optics RAZOR and an American Defense Mfg QD mount. The barrel is an ODIN Works 10.5″ .223 Wylde Stainless Steel barrel with a Primary Weapons CQB comp on the end. The combination of a shorter barrel and the CQB comp makes it perfect for a home defense weapon but the ODIN Works barrel definitely holds up to its reputation as a straight shooter and is absolutely capable of hitting longer range targets with ease. I’ll shoot some 100 yard groups soon and do another writeup for you guys on the accuracy of this 10.5″ AR Pistol.

AR Pistol Upper

THE AR PISTOL LOWER
The lower for this build is an AERO Precision lower that I bought as a set with the upper for this build. Both were Cerakoted Tungsten for a unique look. So far I’ve added a Battle Arms Development BAD-CASS-SA short throw selector and EPS Pins, Phase 5 Weapon Systems Winter Trigger Guard, Magpul K2 grip and an Impact Weapons Components QD End Plate sling mount. There is a new ALG Defense ACT trigger waiting for it down stairs that I need to install.

Another feature that should be standard on ALL AR Pistols is the combination of a Sig Sauer SB15 Arm Brace and an SB15 specific buffer tube such as the KAK Industry Super Sig Tube or Phase 5 Hex-2.  These buffer tubes push the SB15 further away from the receiver making the setup a bit more comfortable to shoulder (Shouldering the Sig SB15 is legal according to the ATF). For this build I installed the KAK Super Sig Tube and its awesome. You can even get an adjustment kit of rings that you slide on before installing the SB15 to adjust how far back it sits.

You also might notice the MagPod on the magazine. These will be available for purchase very soon!

AR Pistol Lower

THE BUSINESS END
The part I get questions about the most is the business end of the upper. Most people seem to really like this setup so here is a pretty detailed look at it. One of the other reasons I like muzzle devices like the CQB comp is that you can put a light right up to the end of the muzzle and not worry so much about it getting damaged in the blast of the rifle or coated in carbon. My setup consists of a Magpul AFG and a Haley Strategic Partners Thorntail Offset Mount with an INFORCE WML mounted on it. The Thorntail Offset Mount is made by Impact Weapons Components for HSP and is an awesome mount for the WML. It has four slots to mount the WML on and can even be mounted cantilevered like mine is.

IWC HSP Thorntail Offset Light Mount 1

As you can see the WML is pushed out almost to the tip of the muzzle. Pushing it further forward not only reduces shadowing in the light beam but also gives you a lot more real-estate to put your hand on a shorter rail. 

IWC HSP Thorntail Offset Light Mount 1

The next few pictures will show you a detailed look at the complete setup and hand position. While using the AFG I like to put my thumb on top of the rail for a solid grip. To activate the light, all you need to do is slide your thumb to the left and the activation button is right there. This is a very effective and comfortable setup.

If you like this light setup and want to put it on your rifle or pistol build, I would recommend checking out www.ImpactWeaponsComponents.com. They have the HSP Thorntail Offset Mount, Magpul AFG grip and INFORCE WML light all in-stock. Plus, if you use the discount code “ar15news” at checkout you’ll save 5% off your entire order. 

This is definitely my favorite AR Pistol build to date. After a few hundred rounds so far I can tell you it runs like a champ and is absolutely a blast to shoot. The bolt holds open on empty mag, no Failure to Eject, no Failure to Feed, etc. Just an all around accurate AR Pistol that I would not hesitate to grab when my life depended on it.

Phase 5 Tactical 4th of July Sale

Phase 5 Tactical has recently released two additional Pistol Buffer Tubes giving them a total of 3 that they produce. The two new tubes are part of their “HEX” line. Last night I installed the new Phase 5 Weapon Systems HEX-2 Pistol Buffer tube with a Law Tactical Gen2 Folding Stock Adapter on one of my AR Pistols. The HEX-2 is designed specifically to be used in conjunction with either the supplied foam pad or the Sig Sauer SB15 Arm Brace. The “HEX” portion of the tube doesnt allow the SB15 to slide all the forward creating a bit more length to the overall setup but leaves a small opening at the rear of the SB15. The HEX-2 comes with a plug for the end of the SB15 brace which allows for some storage capability and is a neat touch. 

Phase 5 Tactical Hex-2 Pistol Buffer Tube 1

Here’s a closer look at this setup. For those wondering why they can’t find any Law Tactical Folding Stock Adapters anywhere, the Gen3 is coming out soon and its going to be a really nice upgrade over the Gen2 which was already a great product. 

Phase 5 Tactical Hex-2 Pistol Buffer Tube 2

Just figured I would share this setup with you guys. I will be giving an in-depth review of the new Phase 5 “HEX” line of tubes in the near future. The whole kit including the tube, castle nut, end plate, foam pad and SB15 plug is available now for just $60 at www.Phase5WSI.com.

The upper has a Centurion Arms 9.5″ CMR rail, 7.5″ KAK Industry 300BLK barrel, Kaw Valley Precision comp, a set of Magpul MBUS Pro and a Fortis Mfg Hammer charging handle.
