I've known a few people that never got polymer lowers to fit mil spec parts and uppers. This includes 80% kits and factory finished polymer lowers.

I had to alter a factory finished poly lower to get it to work, trigger pocket was all fucked up. I still don't trust the buffer area to hold up, so I'll only use it on a dedicated .22 build.
