The XPower-M4 is designed to replicate the look, feel, and action of the real M4. With features that mimic the M4, such as shell ejection after every shot, paintballs force-fed by magazine, and the option of a collapsible or solid stock to disguise the CO2 cylinder, it’s the very image of the real M4. With the carry handle removed, the XPower-M4 can take any standard scope, sight, or mount on its flattop rail.
