When putting my omega 300 can on the upper that does fit, the bolt won’t grab the next round, just rides over the top, bending it and of course failure to feed. Maybe a heavier buffer might solve that? Gun runs fine as is with no can on it. I attempted to put another upper on it and it just doesn’t close quite all the way preventing the rear pin from snapping in. Thanks for any input. |
| It’s a common problem on non-Colt RRs to have a top deck that’s out of spec, sitting too high. The lower needs to be brought in to spec and then reanodized. Intlmilco I believe will get the lower to spec and has an option for reanodizing. |
