"put this in my Cybergun F.A.M.A.S. DMR and it makes great compression and absorbed a lot of force from the cycle and made the gun really quiet compared to stock. the only polymer part is the red part, EVERYTHING else is METAL!! :) nothing bad about this product, highly recommend

"Put into a JG P90 and it fit perfectly. Great product and materials used. Paired with a ASG v.6 cylinder head and a good nozzle i am hitting 380 to 390 with an M90 spring. about a 30 to 40 fps jump. It silenced my gearbox slightly and you hear a pop more than a bang. Highly recommened product.

Fit just right
Fps boost
Silenced my shots pretty well

"I bought this piston head and an ASG ultimate silent piston head for my custom SL8 DMR build, and performed great. Quieted the gearbox, increased fps, was generally awesome.

I had a couple problems with mine, though. First, the screw kept backing out, causing the piston head to separate from the piston head. Not a big problem, probably an easy fix with some thread locker. Second, the aluminum ring around the head cracked, which messed up compression and also caused the threads to strip. Now, my gun shoots 430fps with a .20 at 16rps, so it may have just been too much for the head. Either that, or it was a just a bad head.

For a regular AEG (400 fps or less) I highly recommend this piston head (paired with the ASG cylinder head). Its inexpensive and highly effective. For higher fps applications, I recommend going with an aluminum head.

4 out of 5 only cause mine broke.

ASG Ultimate Ball Bearing Polycarb Silent Mushroom Piston Head for Airsoft AEG
The polycarbonated piston head is equipped with built-in pressure bearings to reduce friction from the spring. The piston head is ventilated where holes in the piston heads ensure that the rubber seals are pressed against the cylinder when the air is compressed. This gives optimal compression of hte air seal and minimizes wear and tear on the rubber seal. The mushroom head piston head also provides a stealth gearbox operation where the aluminum piston head will create a sharp snap sound when fired.
