I'm somewhat new to AR-15's. I have many magazines (C-Products 20 and 30 round) that I have bought over the past two years, but not tried to use until today. Most (10 out of 19 so far) will not feed the round (PMC Bronze 223) properly and it seems to me that the edge of the casing is impacting/hitting the front edge of the magazine just enough to cause a FTF malfunction/jam. The other CP magazines that do work fine, clearly look like the bullet is angled slightly more upward toward the tip and when you push them forward by hand they do not it the edge of the magazine. If you push the round forward with your fingers on the ones that jam, the case edge (where the case and bullet meet) hits the magazines and stops the round from moving forward. These jams can occur if I load full or short loads in the magazines. I cannot send them back, because I don't recall where I bought them.
So, do I file the front edge of the magazine down slightly? Or is there another suggestion as to what may be happening? I cannot post pics. |
