Yep, even with all the fleas it ain't half bad. I trimmed mine out and it shoots just fine. I don't have anything bad to say about a 580 with a trigger job and a bushing swap. I see they're still using M-14's in UKR. Imagine that. Kilt on the battle field by an M-14 or a Maxim machine gun for that matter.
The M-14 was just an improvement of the Garand. There is noting inherently bad about the design.
