    Specs:
    Cold rolled carbon steel
    Manganese Phosphate finish
    Includes one drilling arm, with 5/32 hardened drill bushing, one 5/32 HSS jobber drill a 3/32 hex key, a 0.750" front block with required set screws and an 1/8" hex key.

    A 3/16" drill bushing for the older Geissele gas blocks is available separately.


    The BRDE Universal gas block drilling jig is a combination of blocks used to set up barrels to drill many gas block/barrel assemblies. The set requires exposed gas block journal in front of the gas block to index. If this is not the case, you may still use the block but will need our rear plate and a backer plate and clamps (not included) to index the front block. If your gas block has a pilot hole or flat already drilled, it may not align with this jig's drilling arm. You will have to set up on the opposite side of the pilot.
