I finally got around to somewhat finishing it (no optics yet).
Bushmaster lower receiver
SPR pistol grip (not pictured)
CMT flattop upper with laser etched T markings
CMT chrome-lined bolt carrier assembly and bolt (bolt has been Magnetic Particle Inspected (MPI) w/ charging handle
Bushmaster varminter free-float tube with bipod stud
Bushmaster 20" HBAR chome-lined barrel
I've milled the old FSB down, but haven't finished it yet.
The plan was to turn this into a varmint gun, so something in the range of 4-12x50 or something for the top, and a bipod.
