VTARUVB - Upper Receiver Block for AR-15
A modular AR15/ M4 upper receiver block for performing work on your upper receiver.
You may just use the lower vice block by itself by clamping the lower vice block to a bench vice and attaching the upper receiver to the vice block with the two included ¼” receiver cotterless hitch pins.
Removing the two outer hex bolts from the lower vice block separates it from the upper receiver block. The upper half of the receiver block slides into the upper receiver like a bolt carrier group. The lower vice block bolts onto the upper receiver block to fully support the inside and bottom surfaces of the upper receiver for installation or removal of a barrel. This prevents the damaging of the upper receiver from distortion/twisting/ bending of the receiver when installation/removal of a stubborn seized barrel nut. This also leaves the outside of your upper receiver completely open and free for mounting optics, sights, and accessories.
The upper receiver block also has a hole through the length of the block to act as a bore brush guide for cleaning out the bore of the barrel.
