The NcSTAR AR-15 Ultimate Tool Kit is stored in a padded case and this essential kit has everything you need to work on your M4 carbine, AR-15 rifle, or pistol. This tool kit is perfect for Gunsmiths or any person who repairs, modifies, or builds AR15 rifles. It includes modular AR15,M4 upper receiver and lower receiver vise block constructed from blue hard anodized aluminum for performing work on your upper receiver or 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 0.25 in receiver cotter less 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, or bending of the receiver when installation or 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. This tool kit includes Pro Series AR15 Barrel Wrench, Pro Series AR Lower Receiver Wrench, AR15, M4, M4 A1 and A2 Front Sight Adjustment Tool, AR15, M4 Handguard Removal Tool, and AR15, M4 Magazine Well Lower Receiver Vice Block/Mag Block.
