Wheeler AR Armorer's Vise Block Tool – Upper Receiver Workholding for AR-15/M16

The Wheeler AR Armorer's Vise Block is a gunsmithing workholding tool designed for secure upper receiver clamping during AR-15 and M16 barrel installation, muzzle device mounting, and upper receiver assembly. This hardened polymer block inserts into the upper receiver's magazine well area, providing a solid purchase point for bench vise work without damaging the receiver's finish or chamber area.

The block's design distributes clamping pressure across the upper receiver's barrel extension recess, preventing marring of the receiver while allowing sufficient torque application for barrel nut installation and removal. Compatible with mil-spec AR-15 and M16 upper receivers in 5.56/.223 configuration. Essential for home armorers performing barrel swaps, free-float handguard installations, or complete upper builds.
