Wheeler Delta Series Upper Vise Block for AR-15 and AR-10 uppers
The Wheeler Engineering Delta Series AR Upper Pic Rail Vise Block is designed to securely clamp virtually any AR upper receiver in a vise. It holds AR-15 uppers by engaging the takedown lugs on the bottom of the receiver and, when reversed, holds most AR-10 type uppers in the same way.
It can also clamp any Picatinny rail on hi-rise receivers, standard flat tops or many other firearms with an integrated rail, by sliding onto the rail and clamping it. Machined aluminium construction and precise tolerances ensure a secure grip, essential for removing and installing stubborn barrel nuts and for many other jobs.
