I’m really glad to see a very reputable company coming out with a new Quad Rail. Everyone thought Quad Rails would go bye bye with all the KeyMod and MLOK rails out there but there’s just something too awesome about a quality Quad Rail. Cross Machine Tool knows that and the fact that there are still so many Picatinny Specific accessories out there. Everyone keeps asking for them so a CMT Quad Rail you shall have. Below are some pics my buddy UWOne77 took of his preproduction 12.5″ model.

I’m sure some of you are wondering, what about .308 rails? Cross Machine Tool says they  have no immediate plans for a .308 Quad Rail but, like everything else, I bet if the demand is they will make them. As with other HDX line of rails, these will include a NITRIDED Steel QD Socket on both sides of the rail and are designed from the ground up for hard use. The first run of Cross Machine Tool HDX MOD III Quad Rails are set to be released at the end of October. The 12.5″ is the first shown but I would assume there will be multiple lengths available.

Keep an eye on www.CMTTAC.com and the CMT Facebook and CMT Instagram for more information as these get closer to release.

Aero Precision has grown a ton over the past 5 years. I still remember when they made standard forged upper and lower receivers and the COP Upper and that was it. Nowadays they make everything from AR-15 and AR-10 receivers to handguards to scope mounts to complete AR-15 and AR-10 rifles. Not to mention their capabilities with their sister companies Ballistic Advantage for barrels and VG6 Precision for muzzle devices. 

For a while now they have offered a handguard with a larger inside diameter which works awesome for tucking a suppressor underneath etc but some of their customers have requested a more low profile, slim handguard. That is why they started designing the new ATLAS S-ONE handguard.

The ATLAS S-ONE is the newest addition to the Aero Precision Handguard lineup. Machined from 6061-T6 Aluminum, the S-ONE line of handguards are designed with size and weight in mind, providing the perfect handguard for your lightweight build. Our proprietary ATLAS attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.

The new Aero Taper Lock Attachment System (ATLAS) is both functional and aesthetically pleasing. It features 2 mirrored tapered locking nuts that provide evenly distributed clamping pressure across a custom engineered barrel nut with use of a turnbuckle screw. A ratcheting detent further secures the design while providing positive registration during installation. By design, the even pressure of the ATLAS system avoids distortion of the handguard often seen with current applications during installation.

You’ll also notice at the 12 o’clock position on the handguard there are raised lines. When I handled the first ATLAS S-ONE off the machines at TriggrCon last month, the first thing I noticed was how good it felt in the hand and that those raised lines add just a little extra traction without being uncomfortable at all.

Aero Precision is will be offering the new ATLAS S-ONE handguards in 12″ and 15″ lengths (7″ and 9″ coming soon) with your choice of KeyMod and MLOK and Black or FDE. And if you want to take it one step further, you can even get it paired with the new Gen2 Forged Upper as well.

You can get your order in now for this first run of ATLAS S-ONE handguards with an expected ship date of 8/25/17. Head on over to www.AeroPrecisionUSA.com to pick out your new ATLAS S-ONE handguard.

If you’ve followed AR15NEWS for any decent length of time you’ve probably noticed we build lots of ARs. Some times, as an AR builder, it’s easy to get in a rut and kind of build the same thing over and over again which gets boring. All it takes is a bit of imagination and planning and your next build can be the best one you’ve ever put together. This is the very case with my most recent build. 

Believe it or not I had SBR’d this Rainier Arms forged lower well over a year ago but had no idea what I wanted to do with it. Then it came to me and I couldn’t stop thinking about it. From there it was just a matter of time before I had the parts in hand and ready to build.

Lets start out with a few closer shots. From this angle you can see the Rainier Arms ambi safety, Juggernaut Tactical ambi charging handle and Scalarworks OPS (On Point Sights) fixed rear sight.

Rainier Arms SBR Build 1 - Scalarworks OPS Fixed Sights Juggernaut Tactical Ambi Charging Handle - Rainier Arms Ambi Safety

As I mentioned above, this build got started as a Rainier Arms Forged A-DAC lower that I bought and Form 1’d just before the ATF41P effective date. I added a Rainier Arms forged upper and ambi safety, CMC Triggers Flat 3.5lb Trigger and LPK, Superlative Arms Piston Kit, Juggernaut Tactical ambi charging handle, Geissele MK4 rail and Scalarworks OPS Fixed Sights and Low Drag Mount for the Aimpoint T1 and a SureFeed Magazines 20 Round mag.

Rainier Arms SBR Build 2 - CMC Triggers Flat Trigger Geissele SMR MK4 rail Scalarworks OPS Fixed Sights Aimpoint Micro T1 Rainier Arms A-DAC

Of course as a Rainier Arms SBR build I chose to use their 10.5″ .223 Wylde barrel. Covered it with a Geissele MK4 rail, Arisaka Defense 300/IR Series Scout Light and Inline Scout Mount, SureFire SR07 switch, Scalarworks OPS Fixed Front Sight, Magpul vertical grip and Griffin Armament Taper Mount Supresspr Mount. The Superlative Arms Piston Kit gas block is under there somewhere. 😜

Here’s another angle of the business end on the new Rainier Arms SBR build. From this angle you can now see how accessible the Superlative Arms Piston Kit gas block is under the rail. This isn’t like many piston kits were you have one or two settings. Its more like a Piston Kit that has a built in fully adjustable gas block so you can really tune it in.

Rainier Arms SBR Build - Superlative Arms - Rainier Arms - Geissele - Scalarworks - Magpul = Arisaka Rainier Arms

This next shot gives you a better idea of how tidy things are on this build. It’s got everything I need and nothing I don’t. The Scalarworks OPS fixed sights and mount for the Aimpoint T1 are absolutely amazing. 

Rainier Arms SBR Build - rainier arms = cmc triggers = scalarworks = aimpoint t1 - juggernaut tactical - magpul - geissele

And here it is. Hope you guys enjoyed a pretty detailed look at my new Rainier Arms SBR build. In the end, this SBR turned out even better than I had pictured it but the initial imagination and passion to create another gun is what got it all started. Don’t be in too much of a hurry to just slap together the first complete rifle you can. Take your time with your next build, map it out, think about what would make you smile every time you see it and then build that. 

Rainier Arms SBR Build - rainier arms - geissele - cmc triggers - magpul - scalarworks - griffin armament - surefire = superlative arms piston kit - aimpoint juggernaut tactical

Here’s the full run down of parts for this build. If you want to copy it, be my guest. Would make for a great AR Pistol build too.  

Already had a chance to get the gas dialed in on the piston kit and man this thing is smooth. Will be getting some range time this week with this gun getting it sighted in. Will let you guys know how it runs soon.

These days everyone builds their own AR and for good reason…its a ton of fun, can save you money and gives you good knowledge of how an AR works. One issue that many AR builders run into is finding compatibility issues with the parts they bought. With the popularity of ultra low profile handguards one of the most common issues is gas block incompatibility. Many handguards are so low profile that they can actually come in contact with the gas block itself or accessories attached to the handguard. I recently ran into this issue myself and figured I would share my experience with you.

One of my most recent builds is a DMR style rifle with a BSF Barrels 16″ barrel with a Carbon Fiber Shroud. Because of the carbon fiber shroud (designed to strengthen the barrel, reduce weight and help it vent heat) the gas block seat is .936″ so of course I just ordered any old .936″ low pro gas block.

Everything installed just fine, I slid the Cross Machine Tool UHPR Mod 2 handguard over the barrel, tightened it all down and … DUN DUN DUUUUN … the gas block was touching the bottom of the handguard. Not just close, literally touching. That’s called “unfreefloating” your barrel. 😂😂 This is something I verify every time I build a rifle as I’ve also seen MLOK screws touching gas blocks as well. Anything coming in contact with the gas block / barrel can and will effect accuracy even at just 100 yards.

In a basic beater build you might not care but in a build like this where accuracy is the goal, you have no other choice than to either swap out the gas block or swap out the handguard. Easiest and cheapest is to swap the gas block. Thankfully Cross Machine Tool has just released their new line of J.A.G. (Just A GasBlock) gas blocks which includes a .936 Gas Block specifically designed to fit under their UHPR handguards and many other super low profile handguards.

**One of the only things I actually do like about .936 gas block seats is that the .936″ opening of the gas block is usually big enough to remove without taking off the muzzle device**

While I had the gas block off I also decided to put a second dimple on the barrel so that the second set screw of the gas block would screw all the way in instead of sticking out just to make sure there was adequate clearance.

At this point it was time to reinstall the CMT handguard and check to see how it fit. Flipped it over and definitely good to go! The new Cross Machine Tool JAG .936 Gas Block did the trick and my barrel is now truly Free Floating.

Only thing left to do now is get this blaster to the range. I’ll have a full review of the BSF Barrels 16″ barrel coming soon. If you’re looking for an affordable low profile gas block you can’t go wrong with the new Cross Machine Tool JAG Gas Blocks.

Geissele Automatics just introduced two new products and as always …. Geissele does not disappoint.

First up is the new Airborne Charging Handle which is a nearly identical copy to the original Super Charging Handle except that the ambi levers are shorter making it more low profile. As you can imagine by the name, this model was designed for some special guys who like to jump out of planes with guns but you too can get your hands on these new charing handles at www.Geissele.com.

Now for a sneak peek at the new Geissele SMR MK13 rail. The MK13 is a slimmer and lighter version of the typical Geissele rail. It does have the picatinny rail sections machined in at the 3, 6 and 9 o’clock spots similar to the MK4. You can sign up for notifications at Geissele.com. These will be available for purchase very soon.

I was literally just mentioning the other day how “an AR with an American Flag finish gets me every time”. Apparently AERO Precision was listening because their new Builder Set for the month of March is just that. The March Builder Set comes with a Forged Lower, Trigger Guard, M4E1 Forged Upper and Gen2 Enhanced Handguard (MLOK or KeyMod). All of the parts have a dark gray base cerakote finish and the receiver set has a silver American Flag as well that looks awesome. As always, this is a limited edition set and once it’s gone it won’t be coming back. Get your hands on this unique builder set at www.AEROPrecisionUSA.com
