This AR-15 upper receiver vise block is a high-quality, precision-machined tool designed to fit all Mil-Spec AR-15 upper receivers. This AR15 upper vise block is fabricated from hard-anodized aluminum; it features a quick-detach, modular design valued by gunsmiths. The device permits secure clamping of the upper receiver in a bench vise without risk of crushing, twisting, or other damage. Suitable for a range of maintenance tasks, it is particularly well suited to the installation or removal of barrels and leaves the receiver’s optics rail accessible for mounting accessories. The lower half of the block is placed in the vise and is rapidly attached to the upper receiver using the two supplied receiver pins; the upper half inserts into the receiver in the manner of a bolt carrier group. The two halves are secured together with the included steel bolts, providing full support to the interior and bottom of the Mil-Spec receiver rather than clamping to its exterior. The Vism Upper Receiver Vise block offered by combathunting.com incorporates a longitudinal bore brush guide to facilitate barrel cleaning. The unit is finished in blue hard-anodized aluminum for long-term durability.
