TacFire TL021 Vise Block Upper/Lower AR-15 Polymer Black

The TacFire TL021 AR-15 Upper/Lower Receiver Vise Block is a practical gunsmith's tool designed to cradle your rifle's upper and lower receivers securely in a bench vise. Molded from durable polymer in a black finish, this vise block prevents marring, distortion, or damage to the receiver's finish and critical machining while you work. The block fits into the magazine housing from either the top or bottom, making it quick to swap between upper and lower work, and it is ideal for routine maintenance, detailed repairs, and full assembly.

Engineered for the AR-15 platform, the TL021 lets you hold stripped or completed uppers and lowers with confidence. Whether you're installing a barrel nut, swapping a handguard, pinning a gas block, working on a lower parts kit, or simply performing detail cleaning, this block keeps the receiver stable and level so you can apply torque without worry. Quality construction and a low-impact polymer design make the TL021 a staple for any AR-15 workbench.
