Wheeler 156888 Vice Block AR Upper/Pic Rail High Rise

This innovative AR vise block is designed to securely hold basically any AR upper receiver. It will secure AR-15 uppers by engaging the takedown lugs on the bottom of the receiver. By reversing the direction it will secure most AR-10 style uppers in the same manner. In addition it will secure any Pic Rail on a hi-rise, standard flat top or many other integrated rail guns by sliding onto and clamping the rail. The durable machined aluminum construction and precise tolerances ensure a secure hold essential for removal and installation of stubborn barrel nuts as well as a variety of other tasks.

Specifications and Features:

• For use with a securely mounted, 6" or larger bench vise (sold separately)
• The block's Picatinny rail dovetail clamp is a precision surface. Care must be taken during use and storage of the block to avoid damage to this surface.
• Clamping items into the block's Picatinny rail clamp may result in minor surface or finish marks.
• The Picatinny rail clamp is not limited to upper receivers alone. It is compatible with any other part that has a Picatinny rail interface.
