ReviewsAntonio90I needed this jig for some 80% blanks. The 5mm & 7mm fire control holes drilled so smooth with WD40 at 730rpm on the drill press that I didn't need to buy chucking reamers. Everything lined up accurately when compared to an original select fire receiver from Poland. Unlike other jigs, this one secures the blank to the jig with a bolt eliminating C-clamps which get in the way while drilling. If you're a beginner or experienced builder, I highly recommend this jig.
