FLP-02 "Booster"

This is the Booster, a double plunger pull-to-prime Nerf pistol with swappable barrels. It uses two Caliburn plunger tubes, and either two 6" or two 5.5" segments of K25. It has separate triggers for each plunger tube, and with the swappable barrels can be used for many different scenarios. Included are options for single, triple, RSCB, triple duck's foot, single Mega, single Mega plus two darts, and demolisher rocket barrels. The barrel swap system is pictured- in the front end of the blaster, two stubs of 9/16" brass are glued in, which mate into the barrel mount. The barrel mount can have 17/32" brass stubs glued in for a perfect air seal between the blaster and barrel.You will need two Caliburn plunger tubes, mainsprings (one 11" K25 can be cut to spring both sides), two small (5ishmm diameter) catch springs, six dash 123 O-rings (standard Caliburn/Talon Claw O-rings), two half inch segments of 9/16 brass and an assortment of #6 screws.
