Average Rating


3 pack cobalt drill bits for barrel assembly.  Includes a 3mm, 5/32, and 7mm for drilling all necessary holes. (front sight, rear sight, gas block, and barrel pin).
Some builders prefer to drill the barrel pin with a 17/64 and ream at 7mm.  We will swap the 7mm for a 17/64 cobalt bit for no extra charge if requested in the comment section.
