The Wheeler Delta Series AR-15 Upper Vise Block Clamp, model 156444, is purpose-built to hold AR-15 upper receivers securely while you work. Made from high-pressure, solvent-resistant polymer, it surrounds the upper with non-marring support so you can torque barrel nuts, install barrels, or perform routine cleaning without risking damage to the receiver finish.

This vise block is optimized for both left- and right-hand Mil Spec A2 uppers with carry handles, as well as modern flattop receivers. The included receiver insert with gas tube alignment system helps keep the gas tube properly centered during barrel installation, simplifying builds and maintenance. Ideal for home builders, armorers, and dedicated shooters, it offers dependable workholding in the shop or at the bench and reflects Wheeler’s reputation for practical, well-engineered gunsmithing tools.
