Gun not working properly?

Well I got brand new upgrades for my gun. New gearbox, hop-up, moter, and now wireing. The last time it was put together and chronoed its max was 320fps which is a complete disapointment for spending $150 on those parts. Any one got ideas or suggestoins?

one thing u could do to add som fps is strech the spring out some

Ya but the spring is a M130 spring, ive been trying to get close to making a semi automatic sniper rifle/ light machinegun.

sorry i dont know any thing about springs but im going to guess and say thats good and my idea wouldn't work on it

what parts do you have in the gun, and who did your upgrades?

u sure its not a 130% spring instead of an m130

All the parts came within the gearbox and the gearbox is a JG Golden Eagle Enhanced M130 Gearbox for M4 / M16 Series Airsoft AEG from evike and the motor is a matrix magnum motor and the hop up is a Prometheus NEO Strike perfect HopUp Chamber for M4 series Airsoft AEG. All should have worked.

its hard to diagnose without actually having it in front of me. if your only shooting 320 fps then your obviously losing compression somewhere. you should be able to tell if your getting good compression by just seperating the upper and lower and dry firing it into your palm, if compression in the cylinder is good, then check your bucking

Ya I found the problem. I dont have the right bucking for the gun.

Order a bucking! Duhh(: JK will, hey will u got a cell?

Ya and for a little comfort to every one im getting a new spring to replace the M130 so the gun isnt shooting like a sniper rifle.

Does any one profesionaly install parts in a gun or do work on guns? Im getting a new spring and wireing kit and I dont whant to risk doing any more harm than posible.

ya i got a guy who does it give him a call and hell do most work for $15-$25 heres his number (850)-867-7020 he is going to lower the spring on my aug a3 for me give him a call tomorrow

Awsome you are amazing thanks.

np i found him on here in 1 of the chats
