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.

Cross Machine Tool is running a special promotion with two of their largest retails. From now through the end of the month, if you purchase a Cross Machine Tool Billet Receiver Set (upper and lower together) you will also receive a FREE Cross Machine Tool Muzzle Device. AR-15 receiver sets will come with the CRC556 muzzle device and the AR-10 sets will come with the new CRB Muzzle Brake.

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.

Gas Block Touching CMT rail

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.

More and more it is becoming very apparent that Cross Machine Tool is more than just an AR receiver manufacturer. CMT was not satisfied with just making some amazing receiver sets so they basically starting making everything else. First it was muzzle devices, which they offer multiple models now. Then they came out with some extremely nice AR-15 and AR-10 handguards and most recently they announced they are introducing their new JAG gas blocks. Well, if you add all of those parts up you’re basically only a few parts away from a complete rifle so it only made sense for Cross Machine Tool to start offering complete rifles. 

Currently they are offering a number of different models including a 10.5″ 5.56 SBR, a 16″ 5.56 rifle and a 20″ 6.5 Creedmoor AR-10 rifle as shown below.

I can tell you I’ve built a ton of personal rifles using Cross Machine Tool receivers, handguards, etc. and you simply can’t go wrong with them. If you’re looking for a new factory built rifle or if you want to buy the individual components and build one your self, Cross Machine Tool is an option that is hard to beat.

If you’re an AR builder, you’d have to be hiding under a rock to not know who Cross Machine Tool is. They started out making billet lower receivers, then added billet uppers, innovative billet lowers with intregrated PDW stock systems, AR-10 receiver sets and muzzle brakes. Most recently they have introduced their UHPR line of handguards. First was the MOD1 which deleted all but the very front of the 12 o’clock picatinny rail. Today the new UHPR MOD2 M-LOK rails are available and they feature a full 12 o’clock picatinny rail section with M-LOK mounting slots at the 3, 6 and 9 o’clock positions.

Cross Machine Tool has been teasing us little sneak peeks of a mysterious 9mm PDW for some time but it wasn’t until now that they released information and full pictures of the ARMINI™. The ARMINI™ is a self contained 9mm PDW that takes Glock mags. It features Ambi Controls (something other 9mm AR’s don’t offer), a Non-Reciprocating Forward Side-Charging Handle and an awesome Side Folding Stock that locks into the rail system doubling as a Vertical Forward Grip. It is also extremely lightweight at just 3lb 4oz without the stock or 4lb 2oz with the stock.

The Patent Pending ARMINI™ can be seen at the Northwest Shooting Sports Expo this weekend August 27th -28th in Tacoma, WA. The ARMINI™ takes the term American Sub Gun to a whole new level. Although it may look similar to any other pistol caliber AR, it is not. Everything from the bolt, forward charging handle, receivers, buffer system has been designed around pistol caliber cartridges fed from a standard Glock magazine. Weights- 3lbs 4oz. Pistol configuration. 4lbs 2oz with folding buttstock/forward grip configuration.

The Cross Machine Tool ARMINI™ will be exclusively licensed to Rainier Arms and will be available through the Rainier Arms website or in-store. You’ll also be happy to hear that the ARMINI™ will be sold in a “Pistol” configuration with the stock being sold as an optional product. This makes it so you can purchase your firearm and take it home with you, then submit a Form 1 to SBR it when you’re ready. Production Cross Machine Tool ARMINI’s™ will be available Early 2017.

Cross Machine Tool has recently started to build on their brand offerings with some new products. The CRC (Combat Recoil Compensator) muzzle device is one of those new products. The CRC features dual side ports and forward angled top ports to reduce muzzle rise. The tip of the muzzle device also is machine to mimic the machining on the front of the UPH15 lower receiver mag well. Muzzle brakes are just the beginning as new rails will soon be rolling out as well. The CRC 556 muzzle device is currently in-stock and available at www.RainierArms.com.

Two forward angle brake ports on the  CRC 556  provide greatly reduced muzzle rise & mitigate felt recoil while the front forks distort and reduce flash signature. The external machined flutes on the front flash forks not only reduce the overall weight of the device but also blend with the aesthetic appearance of our Trademark magwell grooves on CMT UHP15 series Lower receivers. Function of the CRC 556 muzzle device is equaled by the exceptional visible manufacturing quality & apprearence you expect from Cross Machine Tool products. MADE IN USA
