LMT dosnt like steel?

[joe dierte]

I just finished putting a LMT Defender together, assembled lower, Auto bolt carrier, 16 inch 1/7, runs great on everything brass, but hates wolfe. I dont usually run steel but a friend brought some out this weekend and it was the first time my rifle had a issue. MY RRA mid length ate this stuff up, but it is all AR, semi carrier, 1/9, etc. Not a big deal but wondering why the steel was an issue.

Shouldn't be, check your parts. I'm an LMT dealer and while yeah things can happen the uppers I've ran have eaten everything thrown at them.

Thats why I wanted one, only thing i havnt checked is the gas port size, but everything else seems fine by switching parts between guns. It seems like a short stroke problem, as it dosnt pick the next round out of any mag, but it throws brass hard. Its pobably no big deal but I would feel better about it if it was a zero malfunction rifle. Thanks for any advice
