Black River Tactical Gas Block Coil Pin Kit

Black River Tactical's MicroPin Gas Block is machined to feature a dimpled cut-out for ease of drilling and pressing a coil, taper, or dowel pin through your Gas Block for permanently attaching to a barrel.

This Gas Block Coil Pin Kit, also by Black River Tactical, includes a cobalt drill bit and stainless-steel spiral coil pin. Pinning your gas block is the only ensure your gas block will never come loose under hard use. This kit just makes it easier.
