    There are only 3 items left in stock.

    The BRDE Universal gas block drilling jig is our next generation of drilling jig, a more versatile and cost effective tool. However, being more versatile, it does take a bit more time to set up and use. Blocks can be purchased by the set or a-la-cart. To drill a gas block, at the minimum, you will need the front block and drilling arm. 

    This item is the 0.625 bore front block only. You may  use this front block by squaring to the upper on a flat surface. You will also need to order the drilling arm if you don't have already. This jig works great with a hand drill. You may want to use a 3mm end mill to pilot drill, depending on the situation.

    Specs:
    Cold rolled carbon steel
    Manganese Phosphate finish
    Includes one 1/4"-28tpi x 3/8" soft point set screw, and one 10-32 set screw to retain the drilling arm.

    The  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.
