In about 200 rounds of 115gr WWB or Federal, I've only had 1 FTF. However when I tried WWB 147gr JHP (crap, I know, but had a box in my safe) or IMI 158gr subsonic, I have a FTF every 2 or 3 rounds. Has anyone else had problems with these types of ammo, or is it possibly something else such as the barrel feed ramp? The jhp were clearly getting stuck on the feed ramp and damaging the mouth of the round. I'm not too concern about those, but I was disappointed about the IMI fmj.
Here's my build: Cmmg dedicated 9mm lower Cmmg bcg Mvb stock with their 9mm buffer Mas defense 9mm side charging upper Ballistic Advantage 5.5" 9mm barrel Psa (metalform) mags AAC Ti-rant 45m |

I had a lot of fail to feed problems with the BA 9mm barrel I had. I swapped it for a faxon barrel and it's gotten a lot better. Shot about 100 rounds yesterday and had one ftf on the last round of a mag.
I also switched to a heavier 10oz buffer and I think that helped as well |

Failure to feed - Rounds look like they are getting hung up on the feed ramp.
As for the buffer and stock, I have an MVB Arc stock. It's a short buffer that uses 2 springs. The buffer is proprietary, I think it's 5.3 oz. I could weigh it tomorrow to confirm. Trigger and the rest of the LPK is Spikes. Thanks |
