so i picked up a used M4 from the local candystore about 2 months ago. it already had a bunch of upgrades already on it such as: mesa urbino stock, carrier comp pic rail, and the magazine was replaced. i know the pic rail is carrier comp cause its stamped in the side of it, but the magazine isnt marked carrier comp...just what is below in the pic. my ? is, is it carrier comp or FFT? i figured its kip's because the rail was his so the magazine is probably as well.
btw, i paid 1450 otd for it. easily 98% and it shoots like a champ. i figured it already had $400 in good aftermarket parts in it (all parts i would have changed to anyway from a new one)....so i basically paid $1000 for a LNIB M4.
thx for the help guys
