Ha! I was going to ask you if you belong to Calguns too. It is a very good site even if you are not in Cali. I have ordered from Exile for other repair kits but not for my 5.56. I have an Olympic Arms ( still on the east coast) at my brothers which I got in 1994 which is still N.I.B.,. I bought it when everyone said get one now or forget having one, then life got busy and set in the safe. The Ca. DOJ is very vague about their laws. The list that bans AR style, lists Olympic Arms but is says AR 15, CAR 15 and PCR, but my rifle is marked Model M.F.R., so some of the people on Calguns said I was good to go (still not sure) with a bullet button, but when I pick it up this summer I may just leave the stripped lower there and use my JD machine lower I got a while back. I am a little leary of calling the DOJ and ask them about it. I have dreams that they show up when I bring it into the state lol. Sorry for the long post I just wanted to explain what I was doing. Good luck on finishing the build.
