This is a official licensed product of Colt including a spring powered M4 and a spring powered 1911. Both shoot 6mm bbs. The 1911 shoots at 210 fps with a mag capacity of 12. But the 1911 now has a loose trigger and can no longer shoot (broken). But the M4 is mint condition with only a couple of scrapes on the top of the barrel but other than that it shoots fine. The M4 shoots at 300 fps and has a mag capacity of 300. I am only charging the price of the M4 since the 1911 no longer works
