so you're saying just keep wearing the gun out more? like I haven't had any malfunctions out of any of my shots all of them that i've shot, but the wear worried me, they look pretty deep, but i dunno. you can barely tell by moving your thumb over them, but def some difference in surface. I contacted LMT and they told me it was normal wear and all the piston rifles did that, which didn't really make sense. does this mean that I'm going to have to replace parts on it all the time just because it's a piston rifle? I bought the rifle on impulse not knowing much about the ar15 platform, mostly just shooting 10/22s and my glock 19, but the local gun dealer that I went to which is Clyde armory (
https://policeguns.com/catalog/) he sold me into the piston mentioning how it had the same function as the ak47, so basically the same reliability, plus my BCG would be a lot cleaner and cooler & all of this sounded wonderful to me being a noob, not realizing it seems like a gimmick and is only eating away at my rifle, which I spent a little more on because I wanted a solid AR rifle that would last and had a reputation.
