TacFire TL021 AR-15 Upper/Lower Polymer Vise Block

Whether you're doing a complete AR-15 build, field-stripping for maintenance, or tackling a receiver swap, you need a way to clamp your receiver safely without marring it. The TacFire TL021 AR-15 upper/lower polymer vise block is a straightforward solution that lets you work on your rifle with confidence. Made from durable polymer, it grips your receiver securely while protecting it from the hard jaws of your bench vise — a detail that matters when you're working on precision parts that cost real money.

This block works with both upper and lower receivers and installs by fitting into the magazine housing from either direction, giving you flexibility depending on which component you're working on and how your vise is oriented. It's the kind of simple, practical tool that turns a frustrating clamping situation into a few seconds of setup, freeing you to focus on the actual work: whether that's reassembly after cleaning, barrel installation, or fitting custom parts. The black polymer finish resists corrosion and won't rust if it gets wet.

For home gunsmiths, competition shooters who maintain their own equipment, and hunters who prefer to handle their own maintenance, this is a small investment that makes every AR-15 project safer and cleaner.
