[QUOTE="bamban, post: 2073429, member: 17722"] When I harvested my 23 inch AR Grendel barrel from a 26 inch take off bolt gun 6.5x47 barrel, I machined a couple of used GI M16 bolts for the 0.135 deep bolt to headspace with. I figure if I ever shear any lugs I have a spare, worst case I could always modify a couple more. I bought the Grendel extractor. This is what the repurposed barrel did first time out. The load is 31.4, not 31.9 as my buddy interpreted my note. Target is NRA SR target, range is 200 yards. PoA for the 2 groups were the # 8s on both sides of the black I used a BAT Machine 1.000 barrel extension that is .300 longer and .8125x20 instead of the standard .8125x16 thread. The BAT BE mated nicely to a heat to fit Bravo Co blem upper receiver [/QUOTE]
