Caliburn - Stubby Butt

CHANGE NOTE 03/31/19 - Updated to maintain quick-change function.

Just on the off-chance that someone wants to use the "GripStrike" with the Caliburn, this should allow that as it deletes the lower portion of the stock assembly.

Includes an optional "wrench" you can slide on under the head of the 1-3/4" length screw to lock the hex nuts.
