The Breakthrough Clean AR-15 Lower Vise Block is a dedicated clamping tool designed to hold your AR-15 lower receiver securely in a bench vise during cleaning, maintenance, and assembly work. Instead of improvising with padded clamps or risking receiver damage, this vise block inserts into the magwell and locks firmly using your rifle's magazine catch—turning any standard vise into a stable, hands-free work station for detailed firearm care.
Built with an integrated hammer stop tool, this block lets you safely dry-fire your rifle during function checks without battering the receiver. The included Pivot Lock feature gives you open access to the barrel extension and chamber for thorough cleaning without constantly repositioning the gun. The whole setup clamps down on any bench vise, so whether you're at a home workbench or a range cleaning station, you get repeatable, rock-solid stability every time you need it.
If you spend serious time maintaining your AR platform rifles, this is the kind of unglamorous tool that pays for itself the first time it saves you from a marred receiver or lets you work both hands on a brush without holding the gun. Breakthrough Clean Technologies engineered it with the shooter who values both gun care and shop efficiency in mind.
Yes. The vise block is designed to fit any standard AR-15 lower receiver via the magwell and engages the magazine lock mechanism to secure itself in place.
No. To engage the magazine lock and secure the block, you must either remove the hammer stop tool or lock the bolt back. Do not close the bolt with the hammer stop inserted in the vise block.
The block clamps to any standard bench vise. No special vise is required.
The vise block includes the integrated hammer stop tool and the Pivot Lock feature for barrel and chamber access.
