Lug-Lok Upper Vise Block from Real Avid uses the superior strength of the
barrel lugs to securely and safely firm the upper receiver of an AR-15 in place
while you are working on your firearm. This unit works to render blocks that
are clamp style completely obsolete. The block is tough aircraft-grade aluminum
and it won’t mar your weapon. The block will also slide through the upper part
of the receiver and straight into the star chamber of the gun’s barrel. As opposed
to blocks that are clamp style, this block from Real Avid takes the torque
pressure off of the parts that are prone to damage and puts the pressure
instead directly onto the steel lugs. This creates a much more stable and
works by the pins, which are adjustable, holding the block directly at the
right working angle while the lock knob makes sure your upper receiver is kept precisely
where you need it to be. This block allows you to smartly work to improve your
weapon by keeping it secure and not damaged. It comes featured with the ability
to torque muzzle brakes and barrel nuts without causing harm to the upper
receiver. The lugs are precision milled to firmly fit into the star chamber.
This version will fit the .223/5.56 AR-15. The block has vice pin retaining
holes and lock knob retaining holes. There is an alignment flange and 2 vise
pins that are stainless steel.
