Sensibly Armed AR-15 Upper/Picatinny Rail Vise Block
The Sensibly Armed AR-15 Upper/Picatinny Rail Vise Block is one of the most innovative AR vise blocks on the market. It is designed to securely hold basically any AR upper receiver with its non-marking surface. It will secure AR-15 uppers by engaging the takedown lugs on the bottom of the receiver. 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 nylon construction ensures a secure hold, as well as a non-marking surface, essential for removal and installation of stubborn barrel nuts.
