Birchwood Casey AR-15 Vise Block for Lower Receiver Magwells

Birchwood Casey’s AR-15 Lower Receiver Block installs in the magwell of standard ARs and equivalent rifles with ease and allows users to hold the receiver in place while performing cleaning or maintenance. Clamps in any vise to make cleaning, assembly, disassembly, or repairs simple, while the soft material of the vise block prevents marring and damage to the receiver.
