NcStar Lower Receiver Vice Block for AR-15 - Blue Anodized Aluminum - VTARLWRVB - 848754015181
Product Description
Assembling, maintaining, or customizing an AR-15 lower receiver requires a secure, hands-free work surface to prevent slippage and accidental finish damage. Standard polymer vice blocks can flex under torque or crack when subjected to heavy armorer operations like castle nut torquing or pin driving. The NcStar / VISM Lower Receiver Vice Block (VTARLWRVB) resolves these bench constraints by providing a rigid, CNC-machined aluminum mounting foundation that locks into any standard bench vice.
Precision-machined from solid billet aluminum and finished in a vibrant blue anodized coating, this vice block slides directly into the magazine well of standard MIL-SPEC AR-15 lower receivers. It engages the magazine catch mechanism to lock the lower receiver firmly in place, allowing armorers to work at multiple angles without the receiver tilting, wobbling, or marring the lower finish. Additionally, it features a built-in buffer tube / receiver extension support extension that stabilizes rear-end components during castle nut installation.
Built for gunsmiths, home builders, and armorers, the VTARLWRVB delivers non-yielding structural rigidity for trigger group installation, buffer tube alignment, and lower receiver receiver extension work. Upgrade your armorer bench setup with an all-metal holding tool built to withstand heavy shop use.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct compatibility with standard MIL-SPEC AR-15, M4, and AR-22 lower receivers utilizing standard magwell dimensions. Clamps directly into standard bench vices (fits steel vice jaws smoothly without slipping).
Installation Sequence:
- Clear the firearm or lower receiver to ensure no live ammunition or components interfere with bench staging.
- Clamp the base of the NcStar Vice Block securely into a bench vice, ensuring the vice jaws grip the lower base flats evenly.
- Slide the AR-15 lower receiver magwell down onto the vice block until the magazine release catch engages with a click.
- Perform lower receiver armorer tasks (trigger install, buffer tube torquing, takedown pin staging) with a stable, hands-free platform.
- Depress the magazine release button to remove the completed lower receiver smoothly from the block.
