| I've added both a green follower and new USGI springs to a couple of my mags and am still having some FTL's with them. It's not every round, usually 2-3 per mag. I can't see anything on the lip that might be catching the round, they look just like the rest of my mags that function flawlessly. Anything else I can try? |

Does the problem happen the same time each time (i.e., on the 18th round)? What kind of feed failure do you experience? Any dents or rough edges on the inside of the mag body? If you use a ruler or similar tool, does the follower run up and down smoothly in the mag? -Troy |
| The follower does go up and down smoothly. It seems to always be on the first round, the 10th round and another one about 25 or 26. I had one round yesterday where the bullet had almost been pushed all the way back into the brass. The feed failure is that the round is just not clearing the mag. I have to pull the charging handle back and then release it again in order to pick up the round. Thanks for the help!! |

New mag springs, particularly the "+10%" power springs, are sometimes so strong that the bolt has difficulty stripping the rounds off the mag. This problem will eventually go away, but you can speed it up by working the follower up and down. This also helps smooth the follower's path in the mag. What kind of ammo are you using? Are your mags a little loose in the mag well (do they rock front to back)? The feedlips may be slightly bent too. -Troy |

I had a similar problem recently with a beat-up ol' mag. The curved area where the feed lips meet the back "spine" of the mag was slightly distorted. The more rounds the thing was loaded with, the rounds would start to "nose down" and barely clear the front edge of the mag. After fifteen or so rounds loaded, releasing the bolt would cause the rounds to slam into the barrel extension and push the bullet back into the case. I managed to sorta fix this one with needle nose pliers, but I'll gladly crush and save this mag when somebody starts selling replacement pre-ban mag bodies.
