ASG Ultimate Ball Bearing Polycarb Silent Mushroom Piston Head for Airsoft AEG
by Mark H. Date Added: March 11, 2013
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.
