As some of you may remember I wrote a few weeks ago about the trouble I was having with an upper receiver that I bought from Model 1 Sales. The rounds were getting stuck on the feed ramps. Well I sent it back to them and they said they polished the ramps and tried the upper on Colt, Bushmaster, and Rock River lower and it worked perfectly. however when I got it back today and tried it, the rounds STILL get stuck, but only on the left side. I thought I saw a post a while back that was exactly the same thing. Can anyone point out the post and/or help me with this problem? I am at my wits end. is there ANYTHING I can do or should I send it back again and ask for a refund???

hope it helps



Do you think this will help? I have tried Sanchez, Center Industries, Colt, and Bushmaster. They all do the same thing.

Really check the left feed ramp. Since the right one works maybe they didn't do a very good job on the left feed ramp. Use a fine round file first then rubbing compound on a q-tip. Can make the ramp smoother than monkey s#!t. Just look at it real closely with a flashlight and operate the action real slow and see if you can pick up the problem.
