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.

Griffin Armament continues to pump out the new products on a consistent basis. After the recent release of their new Griffin Armament AR Furniture Kit, Griffin Armament has just introduced their new PRIMO Gas Block. Its easy to underestimate the importance of a good gas block. The PRIMO Gas Block is an ultra high quality gas block with the ability to use the included set screws or you can go one step further and pin the gas block to the barrel for an bomb proof setup. Its also decently affordable so you don’t have to spend a ton more for a quality product.

Griffin Armament PRIMO Gas Block

The PRIMO Gas Block™ is a low profile billet machined, .750” ID block, made from 416R crucible alloy steel. The gas block has two provisions for mounting, set screws and / or pinning. The included splined pin allows qualified gunsmiths and experienced builders the option of having a military style secured gas block. A 1/8” carbide drill bit and three ton press are recommended for pinning. Knurl grip cup pointed fasteners ensure a secure attachment to host barrel.

–  416R Crucible Alloy
–  QPQ Nitride finish
–  .750″ gas block diameter compatible
–  low profile design
–  included splined pin
–  Knurl grip – cup pointed fasteners
–  inlcuded hex key

The new Griffin Armament PRIMO Gas Block has an MSRP of just $54.95 and is available now at www.GriffinArmament.com.

A few days ago SMOS Arms released a picture of some rails that were in the raw. SMOS Arms is well know for their slim rails that they have OEM’d for other well known companies. What’s cool about these rails they shared are that they are Quad Rails and they feature a modular cutout system. One is for an AR with a standard Front Sight Post or you can add in a small rail section at the top creating a smaller cutout to be used in conjunction with the Noveske Switch Block or possibly other adjustable gas block systems. There really aren’t a ton of details available for these new rails just yet but just wanted to share the sneak peek with you in case you didn’t see it yourself. Of course as with all prototypes, we’ll have to keep watching to see how product units come out.

V Seven Weapons just introduced an updated version of their Titanium Gas blocks. The new version is slightly lighter and looks a bit different. I’ve never used any of the V Seven Titanium Gas Blocks but everyone seems to really like them. They come with a life time warranty, made from Grade 5 Titanium with either a Satin finish or Ion Bond Black finish and can be purchased to fit a .625 or .750 size gas block seat. If you’re looking for a super lightweight gas block for your ultra light AR build, this looks like a great option.

ODIN Works just announced they will be doing something pretty cool for those looking to build a 6.5 Grendel AR. Now when you purchase one of their 6.5 Grendel Barrels you will automatically get a free Nitride BCG and a Gas Block. This eliminates one of the headaches with building alternate caliber ARs which is finding a good BCG and Bolt to go with that caliber.
