Hello,
I’ve got a 16” MK1 REPR that has given me fits and I’m hoping somebody may have an idea of what to try next. Rifle will fire first round without issue but it will absolutely short stroke, barely eject the round but usually not travel far enough back to even sort of grab the next round. Will do this with all different types of ammo and all different types of magazines. After doing it once or twice in the first five shots, usually will do this two consecutive times on shots 2 & 3, the rifle will begin to run normally. Have tried different buffers and springs with no improvement. Gun has been back to LWRC literally at least 5, maybe 6, times over the last several years (first was for accuracy issues in 2016 and subsequent trips were all for this issue) and i get “it worked fine with our lower” or “need to put factory buffer and spring back in it” when I had only changed buffer and spring in hopes of getting some functionality. Local gunsmith took a look and he doesn’t see anything that jumps off the page. I wouldn’t let him get too deep since I didn’t want to do something to possibly void/alter the warranty. Even being so frustrated with it, I cant ethically sell a gun I know has issues so here I am. So here’s some details:
Has the original 2 postion gas block on it
Buffer springs feels as if there’s some sort of binding up issue at the read of the travel. Nothing overly harsh, but it’s different than the first 2/3 of travel.
Gun has less than 200 rounds through it
I’ve run the gun dry and it’ll do it and run it sopping wet with oil and everywhere in between and it makes no difference.
