Went to the range yesterday after my mags have been loaded for a couple of weeks (again). and I am still getting some feed issues. No More FTE's- just 2-4 rounds per mag feed north of the chamber putting them perpendicular, which gets wedged when the bolt closes in on it. The best mag is my original- the one with the angled follower. The other 3 were purchased from the factory and have the 'stepped' follower. My feed ramp is breaking in- still some paint after about 400 rounds. Mags all have the same lip widths as per my 'analog' calipers. Time to send it in? last chance tips before it goes to Ohio? thanks!
