Modified the excellent source file to fit Milspec diameter Buffer tubes, and have internal space for airsoft batteries or wiring. Requires one M8x16 Flat Point Set Screw to lock in to the holes for adjustment on the buffer tube, and 2 M8x16 Low Profile Socket Head Screws to attach the buttplate.

8mm tap is recommended for cleaning up the printed holes and tapping the locking hole.

Added a version for the LCT RPK-16 stock tube
