first off let me say I'm a newcomer to the ar platform but not new to shooting-- so please bear with me.

So my last trip to the range I had three seperate failures to feed(shortstroking?). The fired casing ejects fine, but the next round would "hang up" between the feed ramps & chamber

--All three were from a different mag and all three were Remington umc 55gr fmj. I've shot plenty of this ammo before thru the weapon without any malfunctions. But as far as I'm concerned those three times were three times too many. I guess my question is what do I need to do to remedy this? Different buffer?

Specs on rifle:

armalite m15a4 -- 20" rifle
all internals are factory parts

thanks for the help
