Wheeler 156888 Delta Series Upper Pic Rail Vise Block Black Aluminum Rifle Ar-15, Ar-10

The Wheeler Engineering Delta Series Vise Block is an innovative and versatile tool that is designed for compatibility with almost any AR-15 AR-10 or LR-308 upper receiver. The Delta Series vise block is capable of accommodating such a wide variety of AR-type uppers because it can be attached in 2 different ways. The first method uses a pair of steel detent pins to engage the upper at its takedown and pivot pin lugs with a set of properly sized and spaced pin holes provided for both AR-15 and AR-10 variants. The second option is to slide the vise block onto an upper receiver's Picatinny top rail and clamp it in place. Constructed of durable extruded aluminum the Delta Series vise block is the perfect device to hold an AR upper safely and securely within the jaws of a bench vise in order to perform regular maintenance or critical assembly/disassembly procedures such as torqueing off a stubborn barrel nut.Can secure any pic rail receiver by clamping the rail Durable extruded and machined aluminum construction Works great for aligning free floating tubes with pic rails to flat top upper receivers
