The Wheeler Delta Series Upper Pic Rail Vise Block is purpose-built to securely hold AR-15 and AR-10 upper receivers during maintenance, assembly, and detailed gunsmithing work. Machined from durable aluminum with a black finish, it engages the takedown lugs on the receiver or clamps directly to a Picatinny rail on hi-rise and standard flat-top uppers, providing a solid, non-marring interface for critical tasks like barrel nut removal and installation.

This vise block is ideal for home builders and professional armorers who need a stable way to work on AR-style rifles, from routine cleaning and optic mounting to more involved barrel and handguard projects. Its multi-function design supports both AR-15 and most AR-10 style uppers, making it a versatile addition to any bench vise setup. Backed by Wheeler Engineering’s reputation for practical, well-made gunsmithing tools, it delivers reliable performance every time you secure an upper in the vise.
