From the 508 mm barrel of the m16 , the fragmentation effect lasts out to 150 m to 200 m but the short ( 368mm ) barrel of the m4 develops a lower - muzzle velocity , pulling the fragmentation limit down to 50 m to 100 m M16步槍508毫米的槍管發射后,碎片效果只在150米到200米的距離內出現,而m4卡賓槍368毫米的槍管使用了低初速槍口,將碎片有效距離減少到了50米到100米。
