For my college graduation, my mother(YES MY MOMMY) got me a new Scar 16. I almost fell over. I want to get a new pmag for it, and after some googling I noticed that the new GEN 3 ones are suppose to be very scar friendly, however I was reading that the older ones could cause damage to the gun itself. Does anyone have any experience with the new ones? Do they work out with the scar without any modifactions? Or if anyone has any better ideas for mags I'm open to suggestions.
