I’ve been searching all over trying to find if this topic has been broached but have found nothing. I’m looking at the possibility of running heavies through an M1A and don’t want to pretzel the op rod. I keep looking at the ported and adjustable gas plugs over at Midway but have zero knowledge in this area. All my trusted sources have passed on so now I’m kind of floundering. Does anyone here have experience that they could pass my way to keep me from doing something butt ignernt. That’s the only thing I can assuredly pull off unsupervised is something stupid.
