Breakthrough Clean Technologies AR-15 Lower Vise Block with Pivot Lock

The Breakthrough Clean Technologies AR-15 Lower Vise Block secures your rifle's lower receiver firmly in a bench vise during cleaning, maintenance, and parts installation. The integrated pivot pin lock holds the upper and lower together at the correct angle, preventing strain on the takedown pins and giving you stable access to the bore, bolt carrier group, and trigger assembly without needing a second set of hands.

Machined to fit mil-spec AR-15 lower receivers, this vise block inserts into the magazine well and locks via the pivot pin hole. The durable construction protects your receiver's finish while providing a non-marring grip surface. Essential for serious AR owners who perform their own cleaning and upgrades.
