Been pondering this one since I bought the FM-15 11.5" in 5.56.
I'm not a 5.56 fan, however I like the FM-15 design. Anything to get rid of the buffer system in an AR15.
Anyway. My thoughts are that I could throw a 12.5" Grendel barrel and bolt in it, but my concern is the pressure at the port vs the lighter BCG of the FM-15.
Anyone have any thoughts?
Thanks
