The NcSTAR VISM Upper Receiver Block for AR-15 is a must have for weapon maintenance.  You can attach the lower half of the block to an upper receiver with the two provided receiver pins to create a stable base.  This allows you to clamp the AR receiver to a vise for accurate maintenance work.  By bolting the two halves of the upper receiver to the block damage from torque forces (twisting) can be prevented or mitigated during installation or removal of barrels from the receiver.  The block inserts itself into the receiver just like a bolt carrier group would go in smoothly.  The bottom half of the block can be bolted together with the top half using provided steel bolts.  This fully supported interior and exterior can also provide an accurate ground for mounting accessories and optics.  The upper receiver block also has a premade hole through the length of the block to act as a bore brush guide for cleaning out the bore of a barrel.  This block is constructed from blue anodized aluminum.  US PAT D870840.
