When one magazine just isn't enough. You can now pick up affordable spares for your 400e. Practice mag changes and other speed drills or just spend more time shooting. This spare magazine for the 400e is designed to hold 50 steel .177 cal (4.5mm) BBs. Not compatible with any other ammunition.

OPERATION The magazine is fed by an internal spring. To load the magazine, push down the BB follower first and then use a BB speed loader to fill the magazine. As the magazine becomes full, the resistance to load more BBs will become harder. Stop loading BB's when this happens. Do not overfill the magazine as this will cause it to jam and may damage the spring mechanism.

MATERIALS This magazine was engineered to reliably feed 1000s of rounds for hours of fun. It has a heavy duty steel housing. If jams do occur recommended maintenance is to place a single drop of silicone oil on the BB follower and leave it standing overnight. This will keep your spring properly lubricated and functioning for years to come.

STYLE  Classic M4 style design has been in use for decades.
