Even though it's probably going to be quite a while before I can start, I'm already planning my next AR build. It's going to be an SBR of some kind, either a 9"-10.5" .300 Blackout or an 11.5"-12.5" 5.56, that's optimized for use with a suppressor.
One possibility I'm considering, especially if I choose to go with a shorter-barreled .300 BLK, is a PDW-style stock assembly. I think the concept is interesting and they look really cool, but I don't know much about them. I know they pretty much all require at the very least a custom buffer, buffer spring, and receiver extension, and some require custom BCG's as well, but that's about it. Would they negatively effect reliability? Are they actually useful (for storage and transportation), or are they just a gimmick? Does anyone have first-hand experience with an AR PDW stock? Is there anything else I should know?
As always, thanks in advance.
