Slong Airsoft "Airproof" Aluminum Piston Head for Airsoft AEGs

"Been teching my own airsoft guns since 2010

I will never use another piston head again.

This is the one. Previously I was pretty stuck on Maxx double o ring head, but for the air volume this can't be beat.

As stated in another review, take your O-ring and heat it up with either a blow dryer, heat gun, or just a lighter run around it a few times and let it cool before installation.

I've used countless different piston heads and I'll never go back to a different one

"Fantastic piston head, great machining, and a perfect air seal. When you get it out of the package, take the o ring off and stretch it over a cylinder. Heat it with a heat gun or blow-dryer and let it sit! It fixed the FPS issues I was having.

"The air seal that vomes with this piston head and this cylinder : https://www.evike.com/products/68361/ : is absolutely insane. Buy these parts with a double o-ring clinder head and you'll be all set for a while.

"Good product and does the job.

"Great piston head.
Great tolerances
Good o ring
Great for full cylinder in my build

"Amazing piston head, recommended for any high speed setups. The air recharge is great and keeps you firing with the most air volume in your cylinder as possible. Doing high speed setups recharge and sealing are a must to make it work the best.

Great part
