Bullet nose up- S2 OR

Recommended Posts

Occasionally im getting this failure to feed, (nose up) ammo, a couple of questions, could it be the extractor - too loose or tight, feed ramp needs polishing  or mags (lips and spring ) basically bnib gun less than 300 rnds, this happen 2-3 times per 100 rnds, haven’t mark which mag is doing it,  give your thoughts , thanks

sounds like magazine feed lips to tight causing round to move at a 90 degree pattern rather than 45 degrees. might need some tuning of the feeding lips

It is missing all the graphics but the text is here.  A great article on bullet profiles, COL, and feeding.  You might be able to find a copy with graphics if you are a good googler.
