AR15NEWS.COM – Your AR-15 news source for all new AR-15 accessories, tactical gear and product reviews!

Recently I started a new build. It was centered around a few key components, the Rainier Arms Mod3 billet receiver set, Rainier Arms 16″ .223 Wylde barrel made from a Rock Creek Blank, the LANTAC USA E-BCG and the new Fortis Manufacturing 14″ REV II MLOK rail. I just recently finished this build and will begin the process of shooting and reviewing it. Until then I wanted to give you an initial impression of the new REV II MLOK rail.

I have used many Fortis Manufacturing REV rails over the past few years and really like them a lot. Lately Fortis has come out with a few new rails including the new REV II rails which look great. As you would assume they are a modified version of the original REV rail that deletes the bottom picatinny rail section and forward side rail sections for a super sleek design, lighter weight and more flexibility in mounting your KeyMod or MLOK accessories.

INSTALLATION

The REV II rails mount directly to a Mil Spec AR-15 barrel nut with a rock solid clamp just like the original REV rail. This type of mount is great for a few reasons. One, it creates an insanely solid union between the upper and rail. It also makes it easier for users to upgrade from the standard plastic “Glacier Guard” or other hand guards that use a Delta Ring as they will not need any armorers tools to remove the old barrel nut and install a proprietary barrel nut. Just cut the Delta Ring off, remove the spring, install your low profile gas block and your REV II rail will be on in minutes. Installation of accessories can be done while the rail is installed but can be done much easier by quickly removing the rail instead of installing them while on the rifle.

FIT AND FINISH

Fit and finish on the Fortis Manufacturing rails is second to none with a very nice dark black Type III Hard Coat Anodizing, smooth edges and aggressive lines. Not to mention they just look stinking sexy! As you can see in the picture below I also used the Fortis Manufacturing Low Profile Gas Block which looks great with its similar lines.

FINAL THOUGHTS

Overall I am very impressed with the Fortis Manufacturing REV II rail and would put them very high on the “Recommended List”. They offer these in both KeyMod and MLOK versions all the way from 7″ long to 14″ long.  So far there really isn’t anything I would say I don’t like about the rail. One note I would make is that anti-rotation tabs are a great feature but as you may already know, not all  billet uppers will accommodate them unless they manufacture of that upper has designed it to work with a rial with anti-rotation tabs. This is not an issue with the rail but more of an issue with manufacturers of billet uppers. The Fortis Billet Upper and Rainier Arms Billet Upper work great with them and many others will too. Check out the entire build below. Once I’ve had some time behind the trigger on this build I will update with more reviews on the different components.

Seekins Precision just announced that their new K20 Angled Grip is available for purchase. The K20 angled grip mounts to KeyMod rails and comes in a variety of different colors. One feature I just noticed that I wasn’t aware of before was the included QD Sling Mount at the back of the grip. Pics and Press Release are below. These are available for purchase at www.SeekinsPrecision.com.

Lewiston, ID – Seekins Precision, announced their new K20 Angled Grip.

Seekins Precision is proud to announce that the K20 Angled Grip is now in full production and available for purchase.

Designed as a lightweight, ergonomic alternative to the standard forward hand grip. The CNC billet constructed K20 weighs in at only 1.6oz and features an integrated sling mount and anodized finish.

The K20’s angled grip surface provides the shooter with better control of the rifle and ease in recoil. Shooters will also find that the K20 allows for a faster response time and a more accurate return of fire.

Seekins Precision will be manufacturing the K20 in both the Keymod and M-Lok configurations as well as offering a selection of anodized colors for ease in rifle customization.

“The response we received for the K20 during initial beta testing was overwhelmingly positive” said Kevin Weyrauch, Seekins Precision Business Development Coordinator. “We are excited to be able to add the K20 to our product catalog.”

ODIN Works B1 Low Profile KeyMod Handstop

Posted on April 23rd, 2015 by ar15news

Shortly after SHOT Show 2015 I received a small little box in the mail from ODIN Workswith a really cool little KeyMod handstop inside of it. I was told to wait until they introduced it to post pics of it so I have been waiting. Not sure if there was ever a specific release date on it but I noticed that they were shown in-stock on their website and thought I would share a few pics of mine. 

The B1 Handstop is machined from aluminum but is still lightweight because it is pretty tiny. At first I thought it was going to be too small but once you install it and place your hand on it, it works great. You basically place your Pinky and Ring Finger on the angled portion with  your middle finger against the front of the handstop. Kind of reminds me of a miniature version of the AFG.

ODIN Works B1 KeyMod Handstop 1

I have had mine installed on a Geissele SMR MK4 ever since I received it and really like it. One of the features I like most about it is that it is very small. Being that its made of aluminum, its super solid as well.

The ODIN Works B1 KeyMod Handstop can be purchased for $49 at www.ODINWorks.com. If you’re looking to save a few bucks on it, I noticed you can also get them at www.RainierArms.com.

LANTAC Presents its new Keyed Accessory Mounting system (KAM)

Posted on March 17th, 2015 by ar15news

LANTAC USA has been absolutely awesome to watch over the last year or so. They’ve come out with some really amazing products and continue to introduced new products at lightning speed. Their latest introduction is a bit different than their Muzzle Devices, BCG, Rails, etc in that it is actually a mounting solution. We are all familiar with 1913 Picatinny, KeyMod and M-LOK. Now its time to meet LANTAC’s KAM (Keyed Accessory Mounting) because from what I can see, KAM addresses some issues I’ve personally disliked about both KeyMod and M-LOK. Only time will tell but I’m seriously hoping KAM gains a head of steam like its predecessors and becomes a huge success. Check out the video and information on KAM below.

KAM can be used for the attachment of accessories to all types of surfaces, manufactured from a variety of materials. Metal, Polymer and Composites can all be mounted onto without any damage from galling, slipping or splintering.

kam3

kam3

KAM’s unique locking system is 100% integrated into the accessory and only applies compressive force to the mounting surface. Due to its unique design a powerful force can be applied without any danger of damaging the mounting surface area.

kam3

KAM uses a low parts count for accessories and has a simple / fast to machine hole and slot pattern that also gives design and styling flexibility to the manufacturer.

kam3

KAM is Patent Pending but Free to License for manufacturing purposes, with the only requirement being the inclusion of the KAM logo on the item manufactured with its features.

Different adapter plates and locking ‘ROTO’ nuts can be used to fix the same accessories to tubular / curved surfaces so the system represents true flexibility across all types of design.

More information on adapter plates and nut designs to follow.

Please contact us on info@lantac-usa.com to register interest and receive more information.

NEW!! 2A Armament LITE rails – KeyMod or M-LOK with Ti Nut

Posted on March 5th, 2015 by ar15news

These new LITE rails from 2A Armament look really awesome and seem to be crazy light weight. 2A Armament makes a ton of light weight components for AR’s including receivers, take down pins, muzzle devices, etc. and I’ve heard nothing but great things about their parts. These new rails look like the perfect finish to any lightweight build and come in both KeyMod and M-LOK versions. If you can’t get enough of the light weight stuff, 2A Armament is definitely worth checking out.

2a armament LITE MLOK rail 2

2a armament LITE MLOK rail 1

2a armament KeyMod LITE rail

The 2A Armament™ LITE RAIL M-LOK and KeyMod series was designed as a lightweight rail solution utilizing proven traditional 6061 extrusion, and titanium as the foundation. The LITE RAIL series of rails features the same lightening cuts found on the popular BALIOS-lite receiver sets. When the two are combined, a seamless look is achieved across the top of the firearm. The LITE RAIL is just as capable on any quality forged or billet upper receiver offered from other manufacturers as well. By utilizing a titanium barrel nut, and an innovative 45 degree mounting system, the LITE RAIL achieves a solid lockup with the upper receiver. The 2A Armament LITE RAIL will ship with a 6AL-4V titanium barrel nut. An optional aluminum barrel nut is offered as a separate item for those looking to save maximum weight on a build.

First Look – SI Defense .308 Ambi Rifle Build

Posted on February 17th, 2015 by ar15news

Over the past few months we’ve had the opportunity to work with the guys from SI-Defense in helping spread the word about their new products including their new .308 billet receiver set that features “mirrored ambi controls”. Remember that term as you’ll see what we mean soon. Now that the .308 Ambi receiver sets are hot off the machines, SI-Defense asked if we would want to build our own rifle using these receivers…and of course we’re not gonna turn that down. :) So this is the start to our multipart article showing the rifle we built, what parts we used and then we’ll do additional articles once we’ve actually had some time to shoot it for a while.

The first thing that arrived were the SI-Defense .308 Ambi billet receivers. The mirrored ambi controls on the receivers are pretty mind blowing. When you push on the Bolt Catch, Bolt Release or Mag Release on one side the same button on the other side moves as well. It really is pretty amazing that the ambi controls are mirrored and not just an added lever that is completely different than the control on the right side. The dust cover is pretty cool too in that it is easy to remove/install even with the handguard installed because it snaps into place.

SI-Defense 308 Ambi Rifle 1

A few months ago Rainier Arms introduced their new .308 UltraMatch BCG. Once I knew this build was going down I promptly went on the Rainier Arms website and purchased one. The finish on this thing is a really nice deep Black Nitride that is super smooth. The angled cuts toward the front and fluting at the rear of the carrier look pretty sweet.

SI-Defense 308 Ambi Rifle 1

If you’re gonna build a gun you definitely need a barrel, right?! Right. I’ve posted about AERO Precision barrels many many times before whenever they have a new model to introduce or a special deal etc. but have never personally used one myself. So for this build I contacted my buddy Chad over at AERO Precision to see if I could get my hands on one of their 16″ Mid Length .308 barrels. They are made of 416 Stainless Steel and I’m really excited to see how well they perform. You might be thinking “A 16 inch .308 build? Most guys do 18 inches or more.” and you’re right but I just built an 18″ like everyone else and wanted do something a bit different. Because I know big bore rifles can be a bit ornery I installed a SLR Rifleworks Sentry Adjustable Low Profile Gas Block along with the Rainier Arms Nitride Mid Length gas tube.

SI-Defense 308 Ambi Rifle 1

Along with the SLR Rifleworks Sentry Adjustable Gas Block, I also used the SLR Rifleworks SOLO 15″ KeyMod handguard, Hand Stop and their Synergy BCF muzzle device. It truly makes for one killer looking setup and can’t wait to see how well it performs.

SI-Defense 308 Ambi Rifle 10

Along with making some pretty amazing ambi receivers, SI-Defense also makes a mean looking ambi charging handle called the MACH10 which stands for Modular Ambi Charging Handle for AR10. This specific one has a neat feature where it latches on the inside of the receiver but they will also offer an outside latching MACH10 and a MACH15 charging handle as well.

SI-Defense 308 Ambi Rifle 1

As with all of my builds this one includes a Battle Arms Development Ambi Safety. I don’t own a single AR that does not have one and no I don’t get them for free. Its one of those products that I have honestly grown to love and buy them for every build.  

SI-Defense 308 Ambi Rifle 1

Along with upgrading the Safety I also upgraded the Trigger. I usually use either a Geissele or CMC Trigger and decided to try the Geissele S3G trigger in this build. The S3G is not really designed for a rifle with higher recoil as it has a very light trigger pull and could bump-fire easily so I used the heavier spring that comes with it. This is kind of a trial run and will be interesting to see how it performs in a .308.

SI-Defense 308 Ambi Rifle 1 SI-Defense 308 Ambi Rifle 1

Oooohhhh. Look at that sexy beast!! I also added a Trijicon VCOG, Magpul MBUS PRO sights, UBR stock and a MOE+ grip to finish off the build. I think it turned out to be an one of the best looking rifles I’ve built. 

SI-Defense 308 Ambi Rifle 1

These pics are hot off the press as I just finished this build over the weekend. This week will be its maiden voyage to see how well she runs and get the gas system all dialed in. Will update you with an additional article detailing its performance at the range and hopefully some 100 yard groups. If we don’t get accuracy data on the .308 AERO Precision barrel for that article it will be in an additional one for sure. Below is a list of links for the parts we used in this build.
