SHS High Strength Polycarbonate Piston w/ Steel Teeth for Airsoft AEG Gearboxes (Type: Standard / 16 Teeth / Black)

"This is a great piston. In fact, it was so great that I bought another one.

"Great piston, holds up nicely and is pretty cheap, had it for 6+ months and shows no signs of wear in my Echo 1 Genesis.

"I love SHS parts, and use them in most of my builds. This is a great piston, I even installed it in my CRB (did fix some overspin and gave more consistency). I have a noj swiss cheesed version in my 500fps DMR with 13:1 gears on a 40-90C 11.1 and it lasted for over 10,000 shots with absolutely no wear

"This is a great piston. I am a technician so I search for great pistons for my AEG work and this pistol is my go-to.

Test: 31~33 RPS with 11.1V 5000mah lipo battery (30C) and this pistol lasted 50,000 rounds without much visible damage.

"Used these in pretty much all my builds from standard builds up to DSG builds, swiss cheesed every one of them to make them a little lighter. Very happy with it and would highly recommend it.

"Great piston, really strong. It stood a few shots from a #135 spring, before the motor gave out. Sturdy, light and decently good looking, but it's no Angel Custom.

"These pistons are great absolutely the best pistons on the market great rack and strong construction. Its so strong a lot of people run these on dsgs (very high stress) and pre swiss cheesing!!!!!!

"Gonna keep it short and sweet. Best piston I've ever used. Don't ever get any other piston. This is the last piston I will ever buy. Rack is pre glued and is almost impossible to remove.

"So far so good. I have been using these whenever I upgrade a gun, have purchased about 5 now. As long as you glue down the rack and correct angle of engagement it should be fine. You can swiss cheese it too if you're feeling fancy.

and right now I'm testing it in a 10:1 DSG Set Up. But so far it's holding up just fine. I would recommend this piston to anyone.

"I have both the 14 tooth and 15 tooth pistons, Zero issue with the older 14 tooth one. My 15 tooth one how ever has fitment issues with siegetek gears. You have to shave down the ribs on both upper sides to fit it. (Not to be confuse with tight in the gearbox shell.)

Pros: strong for higher stress builds, price, 14 tooth has good AOE precorrection.

Cons: 15 tooth has fitment issues and AOE is not accurate-needs modification.

"Pros:
+ super light weight constructions

Cons:
- feels light it might break with heavier springs

"The end where the piston mounts is a couple of mm thicker than the G&G pistons I have to replace. Thankfully a local hardware store had the right pitch flat head screws I needed to attach the piston and head together. The weight is really good considering the full metal rack. This was a great time saver and was within a gram of my modified stockers. I had to add a spacer to get AOE back to acceptable. Looks very promising. doc

"It's a good piston I ran it in my classic army p90 for like 5 months and that thing shoots 30 rps, I put it in a classic army delta 12 and it broke but the same thing happened to the original piston so it's probably a aoe problem.

"Calling this a "High Strength Piston" is wrong. My 14.1 Siegetek gears kill these things. The amount of material at the back of the pick up tooth is not enough and always breaks after a while of use. Still finding one that can keep up with the fire rate I want to use but had to turn it down in my Titan to keep it from breaking them until i find that fix.
