dave. i highly doubt that the military will want me compromising the integrity of the M-2's barrel. my luck it'll weaken a spot enough in it for it to explode, lowest bidder and all. i think i am going to get some new QC push handles and gravers and see what i am play around with up there. i am a problem with getting both hands working together so i am not sure how good i can get with a hammer and chisel
