Here's a great rifle with great power. Includes the Hop-Up system and shoots 0.2g pellets.
It has two pellet feeding systems. For the fun of motion and action, use the rotary cartridge magazine which holds 5 shells. The shell casing ejects after each shot. Going for the capacity and not the fuss, try the direct feed tube magazine.

Super 9 Pro has an increased muzzle velocity of 370fps (1.27J) with a .2g BB and an effective range of 117ft. Rifle is 47" long and uses a magazine feed cartridge for maximum realism. Magazine capacity is 25 rounds for direct feed, or 5 shells (included). This is a spring gun, which means it's powered by a spring and must be cocked for each shot. It's fast, clean, inexpensive and easily maintained; it requires no gas or batteries to operate. Also, spring guns are the toughest, most durable of all airsoft guns, because they're made with few breakable pieces. If you're looking for a fun, reliable airsoft rifle that'll look great and perform even better, you've come to the right place.
