This is one hell of a hop up unit

This increases your FPS on your gun, SOOOOOO MUCH, its literally unbelieveable.

I used to use a crappy SRC hop up unit with a systema buckling, area 1000 piston head, and an alluminum piston with an m120 spring, and was very innefficient, it chroned about 330 with a .25. not good with an m120 spring

But THEN, I got THIS HOP UP and it boosted it up to about 360 with a .25, from just switching the hop up chamber, and then in conjunction with a tokyo mauri piston head, polycarb piston, and an area 1000 upgraded cylinder, my gun now gets about 380 with a .25 gram bb.

HOWEVER I DID RUN INTO A PROBLEM, when switching the hop up, and the piston head

Since the hop up chamber seals the air compression very well, it is harder for the gun to suck back air. I was using a systema air nozzle and since the tokyo mauri piston head doesn't have any holes, sometimes it woudn't suck back any air, or in other words, would dry fire every time even when there are bbs in the gun, or the bb would just roll out of the barrel.

I fixed this by cutting out the X shape on the systema air nozzle, that is found on the tokyo mauri, and (I think) classic army air nozzles. Having a regular O on an air nozzle is a bad idea, and I don't know why systema makes them that way. Another easy way to fix this is to replace the systema air nozzle with a tokyo mauri air nozzle, they work just as good. Can always trust tokyo mauri, and you can definately trust Systema, except for the one thing about the air nozzle.

Overall, GREAT BUY, you will NOT be dissapointed with this hop up unit, at least I wasn't
