Ensure you're not left out on the battlefield stranded without ammo, by picking yourself up an extra 600-round magazine for your LCT LCK47 and other compatible rifles. Simply fill the storage compartment on top of the magazine, and wind the gear on the bottom to feed BBs into the spring loaded feeding area. A full steel shell provides optimal protection for the internals while also adding to the overall realism. The specially designed finger grooves offer maximum grip and stability when hastily changing your magazine. Due to the design of all High-Capacity Magazines, they function better once they are broken in and the spring becomes more flexible and can be manually broken in by spraying some light silicone oil into the magazine and loading then unloading the magazine couples times allowing perfectly smooth function, every time. Run onto the battlefield confident you have what it takes to come out on top!
