The Kratos Design Group Gas Block is CNC machined from precision ground 4140 steel bar stock. Featuring a .750 gas journal and a QPQ finish it is an incredibly robust low-profile gas block.
Several features throughout make the installation and maintenance easier.
- Located directly opposite the gas port hole is a small witness hole that you can use to verify proper alignment of the gas block over the barrel’s gas port. Jordan B. is responsible for providing Kratos Design Group with the idea for this hole. It’s a simple and effective way to visually confirm proper alignment.
- On the front of the gas block, there is a small hole that can be used to aid in the removal of the gas tube when needed for replacement or inspection. A 1/16″ punch can be used.
- Our gas block also features a built-in shelf to make drilling easier when pinning the gas block to the barrel. A ⅛” drill bit and ⅛” x ⅝” steel pin is recommended.
- Included are (3) 10-32 black oxide knurled set screws with a Rockwell hardness of C-45. We include an extra screw because they are easy to lose. Also in the package are (2) stainless steel gas tube coil pins.

Received this gas block and have been really impressed with the quality of the machining and ease of install. the sight hole for the gas tube is ingenious can’t go wrong with this gas block definitely will be the one I get for future builds

Got one to review before launch. I must say this is the 6th or 7th build I’ve done and the quality of this gas block is superb. I particularly liked the hole for alignment of your gas port on the barrel. Was a nice touch. Installation was seamless and easy. Put a couple hundred rounds down range and had zero gas issues! I look forward to more products to come out! Thanks again guys!

I got one of these for early review. The installation is simple, and the fit is very very good.
Currently, I have 2,000 rounds through this gas block. A mixture of slow and rapid fire. I have gotten the gas block, gas tube, and barrel extremely hot. So far, with no issues whatsoever.

Legit gas block. Everything speced out perfectly with my mics. Ran this on a select fire 12.5 post sample build. The alignment hole is genius. Also I like the fact that it uses the .400 spacing on the set screws rather than some of the others that have some weird .440 spacing(iykyk) used my SLR jig and was perfect.
