The Ultimate Vise Block from VISM and NcSTAR

When you're ready to take that next precision AR build seriously turn to NcSTAR for the tools you need. The VISM Upper Receiver Block for AR-15 represents the newest innovation for building out your upper receiver. It's a modular two piece design that that can be used in many different ways for a new build, routine maintenance or basic cleaning. You can use just the lower half of the block by using the receiver pins to quickly attach your upper for maintenance work. Using both halves together will prevent damage from the torque and twisting forces of barrel installation. The upper half of the block inserts into the upper receiver like the bolt carrier group. When bolted to the lower half, this unit fully supports the upper receiver inside and out to protect your investment. Running thru the middle of the upper block is a hole that serves as the ultimate bore guide for cleaning your barrel of fouling. This is the perfect vise block for every application. Before your next AR build, make sure you have the VISM Upper Receiver Block from NcSTAR.
