Apex Tactical Specialties 104141 Barrel Fitting Jig - Tactical

The Apex Tactical Specialties Barrel Fitting Jig is a purpose-built gunsmithing tool designed to guide correct fit and alignment when installing Apex Grade semi drop-in barrels in a compatible pistol slide. This Tactical version of the 104141 jig provides stable reference geometry to help the installer verify proper barrel hood engagement, locking surface contact, and overall fit during the fitting process.

Machined from billet aluminum and finished in anodized red, the jig measures 0.85" x 3.65" x 5.05" and is sized for use with Apex Grade M&P and M&P M2.0 barrels. The compact, low-profile design keeps the tool stable on the bench while providing the controlled contact points needed for accurate barrel fitment.

Whether you are upgrading an existing slide with a precision aftermarket barrel or performing custom pistol build work, the 104141 fitting jig is the recommended tool from Apex to help ensure consistent, repeatable barrel installation.
