NEW!! SI-Defense Releases Full Ambi Billet .308 Receiver Set

Posted on October 30th, 2014 by ar15news

In the AR world there are lots of partially ambi receiver sets but that typically just means that they have an ambi bolt release lever. To me thats not really an ambi receiver because you’re still multiple other features that aren’t ambi. I know I’m obviously not the first to feel like that and I can guarantee you that is exactly what SI-Defense was thinking when they started designing their new Full Ambi Billet .308 Receiver Set.

One of the first things you’ll notice is that both sides of the lower receiver look exactly the same. The brain trust at SI-Defense did this on purpose to ensure your body gets used to doing the same exact thing whether you’re shooting with your right or left hand. These mirrored features include an Ambi Mag Release, Ambi Index Finger Grooves and a complete Bolt Catch Assembly on both sides giving you a true Ambi Bolt Hold function which is absolutely priceless when clearing malfunctions (I know you’ve heard me preach about that before).

Upon further inspection you’ll also see that they have also included a Pivot Pin Spring Housing on both sides of the lower receiver. That’s right! This new receiver set even offers an ambi Pivot Pin and Takedown Pin system which is something I don’t remember ever seeing before. A couple of other neat features are the Quick Release Dust Cover Assembly and a Threaded Forward Assist Pin Hole.

So as you can see, this is a very well thought out design that looks just as good. I’ve also heard there will be an AR-15 version of this available as well so keep an eye out for that. SI-Defense is currently taking pre-orders for this new Ambi .308 Billet Set. Head on over to their brand new website at www.SI-Defense.com or call 406-752-4253 to place your pre-order.

**The receiver set includes dust cover, ambi bolt catch, ambi mag release. Forward assist, takedown pins and ambi selector not included but are available for sale in the Parts and Accessories section of their web store.

NEW!! Arisaka Defense Light Mounts and QD Sling Attachments

Posted on October 6th, 2014 by ar15news

A buddy of mine (UWone77) has been playing around with some new products from Arisaka Defense and he seems to be very happy with them. Arisaka Defense is a brand new company (literally brand new, as in “no website yet” new) but they seem to already have some nice designs and understand what components people are looking for. The first components they are making available will be an M-LOK and KeyMod light mount, M-LOK QD Sling Attachment Point and a Light Mount that is designed to mount directly to a Centurion Arms CMR rail. I’ve listed some pictures below. As I mentioned their website hasn’t been finished yet but they have a Facebook page that they have started so you can follow along as they introduce new products.

If you are a Billet Aficionado like I am, you will absolutely need to add the new Rainier Arms Gen 2 UltraMatch ambi billet receiver set to your collection. Priced at just $350 with Free Shipping this should be a no-brainer.

Rainier Arms Forged A-DAC Lowers Now Available for Purchase

Posted on September 8th, 2014 by ar15news

Rainier Arms has officially released their new A-DAC Forged Lowers which means I will be buying one very soon. The A-DAC function is a right-hand bolt catch (integrated into the magazine release button). The A-DAC allows you to hold the magazine release button in (dropping the mag if one is inserted), pull the charging handle to the rear and lock the bolt back all at the same time. There are only a couple other lowers that offer this feature and the Rainier Arms lower is the newest and most affordable of them all.

Rainier Arms Forged A-DAC Lower 1Rainier Arms Forged A-DAC Lower 1

As I’ve mentioned in the past, I could care less about an ambi Bolt RELEASE. I want an ambi Bolt HOLD to help with increasing the speed of clearing malfunctions, etc. There really isn’t any other reason for you to manually hold the bolt open unless you’re clearing a malfunction or inspecting the weapon which in both cases you will want to remove the magazine. The A-DAC system is the perfect solution. Watch the following video that shows how the A-DAC system works.

The original Forged lower will still be available, if you don’t want or need this feature. The Mountain logo has also been added to the left side of the receiver.

Rainier Arms Forged A-DAC Lower 1Rainier Arms Forged A-DAC Lower 1

Benefits:
- Removes six steps from the Manual of Arms when clearing a double feed malfunction.
– The device adds the ability to use the right hand to lock the bolt to the rear while still leaving you the option of using the standard left hand method.
– Greatly reduces the amount of time needed to clear a malfunction.
– Unlike all other devices there is no need to learn to find a new location for your trigger finger as one experienced with the weapon already instinctively makes contact with the magazine release button first to clear any remedial action malfunction.

Trouble free simple design:
- Can be field stripped with no tools.
– Only one additional part is required and is completely internal to the receiver.
– There are no screws to come loose.
– There is no weight added to the bolt catch that could cause it not to lock open on the last round like other devices which bolt on.
– Nothing to snag on clothes or other gear.

Safety:
- Virtually eliminates the possibility of the user’s finger unintentionally entering the trigger guard while locking the bolt to the rear.
– When used, makes it impossible to inadvertently lock back the bolt with a loaded magazine left in the receiver. This prevents the possibility of chambering a round in the event the rifle is bumped causing the bolt to drop.
– Nothing to accidentally trip the bolt release when reloading or clearing a malfunction as it is only a bolt catch.
– Allows you to keep a firm grip of fire control – making it much easier to keep the muzzle pointed in a safe direction when locking the bolt to the rear.
– Nothing obstructing any portion of the trigger guard – preventing any issue with snagging a gloved hand.

The all new Rainier Arms Forged A-DAC lower is available for purchase now at www.RainierArms.com.

NEW!! Fortis Mfg Releases New Aimpoint Mount and Light Mount

Posted on August 28th, 2014 by ar15news

Fortis Manufacturing quietly introduced two new products this week. One is a new version of their awesome F-1 Optics Mount (Aimpoint T-1/H-1 Mount) and the other is a new KeyMod Light Mount. I’ve included pics and details for both new products below.

The Fortis Manufacturing F-1 Optics Mount is one of the cooler looking mounts designed for the Aimpoint T-1/H-1 optic and is now being offered in an Absolute Co-Witness mount height. People have always been asking for an Absolute Co-Witness version of the F-1 Optics Mount which was a Lower 1/3 Co-Witness Mount. Lower 1/3 Co-Witness and Absolute Co-Witness refer to where your Iron Sights line up in relation to the Red Dot. A Lower 1/3 Co-Witness mount is a bit taller so your Iron Sights will be in the lower portion of your optic with the Red Dot just above. With an Absolute Co-Witness mount your Red Dot and Iron Sight will line up together. Having an Absolute Co-Witness mount has its advantages such as being able to sight in your rifle with just your Iron Sights and then line your Red Dot up with them for quick sight-in.

Fortis Mfg also just introduced a new KeyMod Light Mount. This light mount is designed to fit most flashlights with a 1″ body such as the Elzetta Design lights, most SureFire lights, etc. As I mentioned, this is a KeyMod mount and will work with any KeyMod rail. The design of this light mount pushes the position of the flashlight up and forward which makes it much easier to activate the light without having to move your support hand much and also gives you a bit more room on the rail for your hands or other accessories.

Sneak Peek!! CMT Tactical Left Side Eject Billet Upper

Posted on August 18th, 2014 by ar15news

CMT Tactical has really been cranking out new products lately and I don’t think they have any plans to slow down. Here’s a little sneak peek at a project they are working on right now. CMT Tactical just prototyped their first Lefty version of their awesome billet UPUR upper. The best part is it doesn’t look like an afterthought like most left hand eject uppers. It features a forward assist and shell deflector on the left hand as well making it a true left hand setup. Not to mention it has the usual CMT Tactical sexy lines.

Be sure to stop on over at the CMT Tactical Facebook page and let them know if you want them to make this Southpaw Dream a reality. You can also take a look at www.CMTTactical.com to check out their full line of billet lowers and uppers. 

NEW!! Rainier Arms Enhanced Ambi Accessories Combo Kit

Posted on August 13th, 2014 by ar15news

I swear I had absolutely nothing to do with picking the components of the new Enhanced Ambi Accessories Combo Kit from Rainier Arms, but if you looked at some of my rifles you probably wouldn’t believe me. The components that make up this kit are some of the most popular accessories for AR-15 builds and not just because they are cool, these are high quality upgrades. The kit includes three accessories that I would say are absolutely the best in their field, the Rainier Arms RAPTOR ambi charging handle, the Battle Arms Development BAD-ASS ambi selector and the Norgon Ambi Catch magazine release. It also includes the Seekins Precision Enhanced Bolt Catch and Billet Mag Release. Instead of buying all of these accessories separately, you can purchase them all together and save yourself about $40 over the usual price. Check it out now at www.RainierArms.com.

The AMBI-CATCH(tm) is a patented “drop-in” replacement of the original magazine catch for M16A2 Rifles, M4 Carbines and other firearms that use an M16 type magazine.

When installed, the Ambi-Catch(tm) also gives both right and left-handed shooters the flexibility to choose from several different magazine release methods.

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.

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.
