Thats an awesome joke!

I bought a repro for a friends carbine last year. His father was 17th Airborne and carried an M1a1. We didn't like the blued metal or the sort of suede cheekpiece.
I parked the metal and found an old set of leather chaps, well worn and the right thickness for a cheekpiece. Modified some brake rivets and put it all back together. It looked much more authentic when done.
