Has anyone got the 6mmbr to feed right in an ar15. If so what mag and what mods were done to it to feed. i am working on a 30br ar15. I am hoping to get a slightly heavier bullet (10 to 15 grain increase) at the same speed as a 6.8.

I am using straight PRI 6.8 cases but, 1st generation.
They feed well enough that I had a triple that sounded like a 3 round burst.
Very light Geissele trigger:D

One thing that helps with mags is bending the top loop of the spring up where it contacts the front of the follower and the hook at the same time while the spring is verticle.
