This is a brand new multi-function SFB with side air and airsoft bullet platform that I developed recently. It is a very flexable 3 in 1 platform. You can do SFB and side air and softair bullet shots. The very unique design about this platform is all the nozzles are adjustable and turnable for easy fine tune and different needs. 
 
It will come with follows as standard kit:
1x 33cm x 6cm x 33cm x 6cm platform with 3 main and a side adjustable nozzle sets.
 
Note: Valves sold separately
