The Apex Tactical Barrel Fitting Jig (brand part no. 104141) is an aluminum fixture built to hold a barrel steady while fitting Apex-grade M&P barrels or other aftermarket M&P and Glock barrels during installation. Apex Tactical Specialties recommends pairing the jig with a half-inch safe-edge file, sold separately, to remove material precisely without gouging the barrel or damaging the feed ramp. Having a dedicated jig rather than fitting a barrel freehand keeps the process consistent and repeatable, which matters for a gunsmith fitting barrels regularly rather than doing a single one-off job.
