So I am having a small issue. AR15 failing to feed first round. Seat the mag, rack the charging handle and the round gets stuck between the BCG and the chamber. The ammo is Frontier 223. I swapped out three different mags and all had the same effect. Every round. However loading American Eagle 5.56 it has no issues. This is not a new build, just never used the Frontier ammo before. It's always been American Eagle or Winchester
I've looked at the feed ramps they look OK, seem to be a smooth transition from ramp to chamber.
Any thoughts?
