TacFire TL008308 Lower Receiver Vise Block AR-10 .308 Winchester

The TacFire TL008308 Lower Receiver Vise Block provides secure, non-marring workholding for AR-10 and .308 Winchester platform builds and maintenance. This precision-machined block eliminates the risk of receiver damage during assembly, disassembly, and modification work.

What Makes This Different

Unlike universal vise blocks that rely on external clamping pressure, the TL008308 inserts directly into the lower receiver's magazine well for internal support. The block's contoured design matches AR-10 receiver dimensions precisely, distributing clamping forces evenly across reinforced areas. This approach prevents stress concentration points that can crack or distort aluminum receivers during heavy-duty work.

Key Features

• Precision-machined aluminum construction with Type III hard anodizing
• Internal magazine well support eliminates external receiver stress
• Compatible with all AR-10, SR-25, and .308 Winchester platform receivers
• Non-slip textured surfaces prevent rotation under torque
• Integrated relief cuts accommodate various magazine well configurations
• Compact 4.2-inch length fits standard bench vises
• Matte black finish resists corrosion and tool marks

Professional gunsmiths and serious builders rely on proper workholding to maintain receiver integrity during barrel installations, trigger work, and parts fitting. The TL008308's internal support method allows full access to all receiver surfaces while maintaining rigid positioning. This block handles the substantial torque requirements of barrel nut installations and heavy modification work without receiver flexing.
