I'm looking to upgrade my aeg, so I purchased a PDI 300% AEG Spring. I was wondering what this spring is rated at, because now my aeg is shooting at a lower FPS. Below I have listed the airsoft parts I have with my current gearbox setup.
Deep Fire 7mm Gearbox
Deep Fire Bushings
SHS Cylinder Head
SHS Air Nozzle
SHS Piston
SHS PIston Head
Element Spring Guide
SHS Anti-Reversal Latch
Deep Fire Hop Up Bucking
Guarder SP150 AEG Spring
SHS Gear Set
Deep Fire H-hop nubs
Deep Fire Tightbore Barrel
SHS High Torque Motor
11.1v 1600mah 20cc Firefox Lipo Battery
Once I installed the PDI 300% airsoft upgrade spring, my FPS was 460 with .20g BBs. On the other hand, when I had the SP150 spring, my gun was going 500 FPS with .20g BBs. From what I have heard, this setup should be going 500 FPS or more.
I have actually heard people say that the SP150 spring can go 600FPS, but that is definately not true. 500 FPS is possible with an SP150 spring, but most likely you will not get that. A reason why you may not be getting the FPS you expected is because you need a beter air seal. You might consider getting a bore up set from a manufacturer such as Guarder or Deep Fire. Other than that, you gearbox sounds good, but If you want to get an even higher FPS, you can just get a harder spring. Many people are acutally suprised because they get a lower FPS than they expected with the PDI 300%.

Q. Which Airsoft Piston? A. SHS Airsoft Piston
The stock piston on my M4 recently stripped, so I was wondering what a good standard airsoft piston would be. I've been looking around, but I just couldn't decide which one to get.
Before my piston stripped, it was shooting around 385 FPS with .20 g BBs and about 330 with .25 g BBs. I have a 9.6 nunchuck style battery. I have SHS gears and an m120 AEG spring.
I'm thinking about getting a piston with full steel teeth or 7 steel teeth on it. Do you think this is good?
Since you are just looking to find a replacement for your AEG, you don't need to spend a lot. The pistons with steel teeth is probably a little over kill; at most your going to want a piston with a single steel tooth.
Some people would say you should get a G&P Polycarbonate piston, which is a great piston, but I think there are some better ones out there. If I was you, I would purchase the SHS Airsoft Piston with a single steel tooth. The SHS piston is not a polycarbonate piston, but it is instead made out of nylon. Nylon pistons have some advantages of a polycarbonate piston.
Another alternative to the SHS piston is the Element lightweight airsoft piston. The Element piston is a good pisotn at a decent price and recommended if you want to be as cheap as possible.
