Good old fashioned BB gun fun with a modern SBR twist. The StrikeForce Magazine holds 30 .177 caliber steel BBs at the ready and is where the two CO2 cartridges (not included) go that are required to power the fun gun. Be sure to stock up on these extra StrikeForce Magazines and plenty UX Precision BBs as you will go through them quickly with the 1400 round per minute rate of fire. Super easy to load. Pull the BB follower down and load BBs through the loading port of the mag. Use a speedloader as an assist to speed up the loading process. Put a drop of silicone oil on each CO2 cartridge before inserting into the mag and never leave capsules in the magazine. It is best to remove them after each range or target shooting session.
