Hey guys, This is my second ATI installation. Aside from the usual dremeling necessary to get the receiver bolts to line up, the first one went fine. Did the necessary filing on the second, bolts line up and thread properly. However, any time the rear receiver bolt is tightened, the bolt handle will only pull halfway, then stick. Take rear receiver bolt out: cocks just fine. Place the rear receiver bolt in: works just fine. Start threading a tiny bit of the receiver bolt: still works fine. As soon as I screw the rear receiver bolt into it's cap, even just enough so that the bolt and cap will stay together, the cocking handle locks up again halfway. I'm certainly not overtightening because the bolt head and the bolt cap head aren't even close to touching the sides of the receiver cover. I've tried removing a bit of the inside stock material. No-go. I've tried spreading the back edge of the receiver cover so it wouldn't pinch so tight. No-go. So, as long as I don't tighten the rear receiver bolt AT ALL, I can pull the charging handle back. But leaving it like that I can easily turn the rear receiver bolt with two fingers and the cap will fall off with any encouragement. Yeah, I know, it's the ATI stock's fault. Not gonna ship it back. But I'm also not putting it back into the factory stock. A man has his pride, after all. Hopefully this is just something dumb/easy that I'm overlooking. Help, please. -'bridge PS I think a permanent thread on ATI stock install problems/solutions/experiences would be very helpful.
