The NCStar AR-10 Upper Receiver Vise Block (brand part no. VTHAR10UVB) is sized for 7.62×51/.308-pattern AR10 upper receivers, giving you a stable way to clamp the upper for assembly and maintenance. Made by NCStar, it lets a builder or armorer handle barrel, handguard, and muzzle device work on the larger AR10 platform without the receiver twisting in the vise. It’s the AR10-specific companion to NCStar’s AR15 block.

Key Specifications

• It’s machined to fit AR10 (7.62×51/.308) upper receivers specifically, rather than a generic clamp.
• It supports barrel and handguard installation, giving the leverage a torque wrench needs without stressing the receiver.
• It also aids general maintenance tasks like muzzle device changes where the upper needs to stay locked down.

Frequently Asked Questions

Will an AR15 block work on my AR10 upper instead? No, the AR10 upper is a different size and geometry, which is why this block is machined specifically for the 7.62×51/.308 platform.

Does this block include the vise itself? No, it’s a vise-block insert designed to be clamped into a bench vise you already own.
