shaker I see that SEI M14 on GB was built on a Poly Tech receiver, I've been reading good and bad about Poly Tech, is this generally a hit or miss receiver or more hit than miss? I guess LRBs the best and then there are the betters like USGI and others. Poly Tech is just good huh?
...but LRB has had its issues.
I rate them in this order:
1) Any SEI receiver
2) Poly Tech & Norinco
3) LRB
4) All others
