So I was at the range today to zero my Noveske & LMT...the Noveske ran like a champ but my LMT 14.5" wouldn't feed at all with various kinds of ammo and magazines. I had to charge each round manually.
Is it likely that it needs a H buffer and new buffer spring? Any recommended brands? All the ammo and mags ran flawless in the Noveske.
