@@mattvanourney128 colt mags are unobtanium...i dont care what features the glock mags may or may not have. i will never buy something that doesnt take glock mags. will the upper work on a lower that take glock mags?
@@jonvenusti I have no clue if the gun will work on another lower. My comment is that glock mags have there negatives. Colt mags are easy to load and are available.
