Compatibility: These mags will fit both the FX Impact M3 and the M4. The M3 mags also fit the M4's. 

The FX Impact M4 we have redesigned the high-capacity magazines. The new magazines are made from a different and stronger material and have a new internal mechanism to ensure the inner drum will rotate smoothly even when fully loaded with some of the heaviest slugs on the market. The magazine retains the same shape and size, the inside of the lid has been slightly grooved to accept longer projectiles.
