I'm in the market for another .308. I already have a 21" DSA standard FAL and I'm considering a second. Of course I have to consider an AR type and also an M1A varient, however part of me thinks I should stick with what I know and what I have. At this point reliability is more important to me than accuracy at distance, so again I'm pointed to the FAL. This is my opionion mind you. Having said that, what is accuracy like between these two barrel lengths from a FAL. For comparison, my 21" will hold about 2 moa until it heats up and then creeps up towards 4 moa. I put this here cause I like MBR and its been a snooze lately.
