KAK Industry 7.62×39 AR Pistol Build and Range Report

Posted on October 20th, 2014 by ar15news

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.

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.

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.

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.

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.

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.

AR Pistol Build Details and Pictures

Posted on August 4th, 2014 by ar15news

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.

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.

New Swag and Combo Deals at American Defense Mfg

Posted on May 29th, 2014 by ar15news

Many of you have probably noticed American Defense Mfg really branching out this last year. Not only are they coming out with a new rifle called the UIC (Universally Improved Carbine) but they’ve also started adding stuff to their website such as Optic / Mount Combo Deals and upping their Swag game too. 

The Combo Deals are great. They basically pair a high quality optic with one of their awesome mounts at a great price. Most scopes/optics don’t come with a good mount and everyone knows you need a good mount if you want to get the most out of the scope. Instead of having to shop for an optic and then look around for a mount, you can just check them out in one place and from what I’ve seen, get a better deal too. The most recent combo deals they’ve added are the awesome US Optics scopes paired with different ADM Recon mounts but they have a wide variety from other manufacturers as well such as Aimpoint, Lucid, Primary Arms and Vortex Optics. You can view them all at www.ADM-MFG.com

I’m sure many of you are also pretty big fans of American Defense Manufacturing so you might be happy to see they’ve had some nice PVC patches made featuring their new ADM logo. For just $6 you get all three of the 2″ x 2″ velcro backed patches. These, and all other ADM Schwag, are available at www.americandefensemanufacturing.com/browse/category/schwag/

Aimpoint Mount and Optic Combos = Great Deals at ADM

Posted on April 4th, 2014 by ar15news

The guys over at American Defense Manufacturing (ADM) have been working overtime this year. Not only have they been testing their awesome new UIC which stands for Universally Improved Carbine, which we’ll tell you all about soon, but they’ve also been adding some great combo deals to their website. The latest set of combo deals are the ones I’ve been waiting for. The Aimpoint Combos! These deals are perfect for anyone who is looking to pick up an Aimpoint and then upgrade the mount. You can definitely same some money this way. Here are a couple of the deals I noticed and thought, now that’s a good deal.  

They are offering an Aimpoint PRO with 4 different mount options for just $504. If you were to buy these separately you would pay $400’ish + Shipping for the PRO and about $130-140 + Shipping for the mount. Just doing some simple math you can see that you’re saving $30-40 plus lowering your shipping cost.

620 ADM Aimpont Pro and QD Mount Combo 1

Perhaps the best deal though is on the Aimpoint T-1’s. Many of you probably know that Aimpoint T-1 prices skyrocketed last year. To purchase an Aimpoint T-1 with nothing more than a basic crap mount is going to run you somewhere between $650-700+ depending on where you buy and if you want the 2MOA or 4MOA dot. Yes, the T-1 is an awesome optic. I have one and love it. But then you need to upgrade to a better mount it really starts to get prohibitive. Thankfully ADM is able to save you some major coin by bundling the Aimpoint T-1 and one of three different Quick Release Mounts for just $643. And these are the 2MOA Red Dots, not the 4MOA too. You’re easily saving over $100 on this combo deal. 

620 ADM Aimpont T-1 and QD Mount Combo 1

As if that wasn’t good enough, ADM doesn’t stop at just the Aimpoint PRO and T-1. The offer packages for the H-1 (slightly less waterproof than the T-1), COMPM4 and the 3X Magnifier as well. Its nice to have a source like this. Buying high quality optics and then upgrading their standard crap mounts to nice ones like what American Defense Manufacturing offers is never easy on the wallet but its nice to know if you’re gonna do it you can save a good amount at the same time.

NEW Upgrade!! Tac Lever for American Defense Mfg QD Mounts

Posted on October 4th, 2013 by ar15news

American Defense Manufacturing recently announced a new Tactical Lever upgrade option for their awesome QD Scope Mounts. The Tactical Lever is an inexpensive option that gives you some additional material to grab on to when using gloves, etc. Its kind of like the popular extended latches on charging handles. The Tactical Lever is available as a standalone $18 upgrade for those who already own an ADM QD Mount or as a FREE upgrade when purchasing a brand new mount from ADM. These are definitely a nice option to look into. If you don’t already have an ADM mount you might want to look into getting that squared away too.  : )  Check them out at ADM-MFG.com.

620 ADM Tactical QD Lever 1

Upgrade your existing standard lever to the new Tactical Lever. Price is for each assembly. If replacing the levers on an AD-Recon or any other dual throw lever mount, you will need to order two assembly’s. These levers will fit all American Defense Mounts except the AD-15R, AD-Delta and the AD-RMR-RH. ( Extended thumb pad will face upward. ) NOTE: Some mounts ( mostly older models ) use the smaller .187″ bolt, compared to the new .203″ bolt. To tell what bolt size you need, remove your throw lever assembly from the mount. With a calipers, measure the width and height of the throw lever cross bolt. If both measurements are .187″, you need a .187″ bolt. If the width measures .203″, you need a .203″ bolt. Alternatively, If 2 Quarters and 1 Penny fit snug in the cross bolt slot on the bottom of the mount itself, you need a .187″ bolt. If 2 Quarters and a Nickel fit snug, then you need a .203″ Bolt. Includes Tactical Lever, Bolt and spare adjustment nut.
