Brownells AR-15/M16 Lower Receiver Vise Block

The Brownells AR-15/M16 Lower Receiver Vise Block securely holds an AR-15 or M16 lower receiver in a bench vise during gunsmithing work. Designed to protect the receiver from damage while allowing hands-free assembly, disassembly, and maintenance tasks. Compatible with standard AR-15 and M16 pattern lower receivers, this block provides a stable, non-marring platform for trigger group installation, takedown pin work, and other lower-receiver operations.
