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 the idea behind 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.

    I haven’t used this GB yet but I have mocked it up on it’s future home. This takes a lot of the guesswork out of building an upper with the peep hole to help guide proper alignment. I will be sure to keep these Gas blocks around for all future builds.
