Max-11 feed issues

[MudRhino]

My max-11 is struggling to feed rounds. On average, it's only able to successfully feed a few consecutive rounds before jamming. It works fine with the factory upper. Gun has always been well oiled (have tried it with oil wiped clean, moderate oil, and dripping).

I've read about guys having issues with their feed ramps when running the max-11 and fixing it by bending the feed back slightly up with a crescent wrench and cardboard. On closer inspection, the gap between the feedramp is definitely larger with my max-11 than on the stock upper and when i feed a dummy round very slowly on the max-11 the bullet 'jumps around' a bit before entering the barrel.

Has anyone else had this issue and managed to fix it? Anything special I need to know before I attempt to (very slowly, carefully, and incrementally) bend my feedramp up?

Side note: I have an 86 model with the feed ramp welded on the right side of the gun, if that changes anything.

Thanks in advance.

What mags are you using? I read sometimes that there are barrel alignment issues. Richard usually responds in a fe hours or you can ask here: http://www.uzitalk.com/forums/forumdisplay.php?82-MAC-10-Talk

I have an 86 gun too and it runs flawlessly with the Max-11. I would reach out to the folks at Lage before attacking the issue with a crescent wrench.

What gr ammo are you using? What mags are you using?

I've tried 115 gr and 124 gr and I'm using steel magazines.

Check out this site to see if it helps a little. Especially, the pitch of the round when it sits in the magazine. Although, your problem may stem from a misaligned feed ramp on your max-11. Send it back for repairs. Lage are good peoples, they'll hook you up.

I had the exact problem as you. 86 dated gun. I bent up the feed ramp with a wrench. If you search on Uzi talk you can probably find my thread. I asked and got the measurement off the.base of the receiver to the top of feed ramp. Its just sheet metal and easy to bend.
