Re: Would you buy a polymer AR lower receiver?
believe me, I put a lot of stress on the lower receiver!
Alloy is plenty light enough for me and has worked this long, I'm not gonna stray from it.
The carbon 15 is hilarious to pick up at 3.9 lbs but an Aero precision/Mega arms lower is only $140 and less worry.
That being said, I know there are plastics out there that are extremely tough and could do the job but I want metal personally.
