if stupid aero precision would STOP the blem lowers for 55 bucks i could stop buying them. I mean if i have a lower i cant just leave it naked and alone and afraid right? I was doing fine with a 556 cmmg ar. then i found those blems bought 1 to see how bad the blem was.... was one single VERY TINY inconsistency and that turned into a 300blk. 2 months later here comes 2 more lowers. a 204 ruger and still up in the air with the other, im leaning towards a teppo jutsu 458. And once those are finished only god knows what calibers the hairs in my butt will want built lol.
