Black River Tactical MicroPin Gas Block

The Black River Tactical MicroPin Gas Block is different in that it features a flat and dimpled face for easing drilling and pinning to a barrel. Instead of relying on two small set screws to provide friction tension, which come loose under heavy use; the MicroPin Gas Block offers the added security of using a solid dowel, taper, or coil pin for permanent lock-up.

The Black River Pinning Kit can be purchased seperately here, which includes a drill bit and a roll pin.

Made of precision CNC machined 4140 through-hardened Chrome-Moly steel. Finished in Mil-Spec Black Oxide.
