Breakthrough Clean BTAR15LVB AR-15 Lower Receiver Vise Block Tool

The Breakthrough Clean BTAR15LVB Lower Vise Block secures AR-15 lower receivers during assembly, maintenance, and parts installation without damaging critical components. This precision-machined tool eliminates the frustration of trying to hold receivers steady while installing trigger groups, buffer tubes, and other components.

What Makes This Different

Unlike generic vise blocks that can crush aluminum receivers or slip during use, the BTAR15LVB features contoured surfaces that distribute clamping pressure evenly across the magwell. The tool's hardened steel construction withstands repeated use while protective coating prevents scratching of receiver finishes. Standard bench vises often require improvised padding or risk damaging expensive receivers.

Key Features

• Precision-machined steel construction for long-term durability
• Contoured magwell interface distributes clamping pressure evenly
• Protective coating prevents scratching of receiver finishes
• Compatible with standard bench vises and gunsmithing fixtures
• Fits mil-spec and commercial AR-15 lower receivers
• Compact design stores easily in toolboxes
• Non-marring surface treatment protects aluminum components

Professional gunsmiths and home builders rely on proper fixturing to achieve consistent results during AR-15 assembly. The vise block maintains receiver alignment during trigger installation, preventing binding issues that occur when components shift during assembly. Competition shooters appreciate the stability this tool provides when fine-tuning trigger systems or installing match-grade components.
