308 AR-10 / SR-25 Upper Receiver Vise Block Armorers Gunsmith Fixture
This high quality armorers tool is made from NO-M.A.R polymer to protect the lugs and rail of your upper receiver. With care and proper handling you should be able to install any standard barrel designed to fit flat top AR type 308 receivers.This fixture will allow you to work on your upper with the bolt and charging handle installed or removed, while clamped firmly in any shop vise that opens at least 4 inches wide. You can clamp it vertically for cleaning  or horizontally for barrel work with the use of the flat top rail cap, to protect your weaver rail from scratches and abrasion. This fixture comes with two Lexan poly carbonate Anti-Torque plates (pat-pend) to positively locate your upper securely in the fixture during gunsmith work. The Anti-Torque plates will allow you to securely work on your receiver on top of your workbench without the worry of scuffing or scratching your receiver and give you a firm hold to steady the receiver on any flat surface. The upper rail block is extra thick and is the full length of your receiver providing great full support when held in your vise. Your vise may have jaws that are smaller in width than your receiver, this block set will allow the pressure from the vise to be evenly distributed to the full width or your receiver, increasing the holding power and decreasing the risk of deforming your receiver by applying too much force on too small of an area. The patent pending Anti-Torque plates hold everything together, not only simplifying installation into your vise, but also eliminating the chance of block rotation during barrel removal or installation.
