Matrix T6061 CNC Aluminum Bearing Piston Head for Airsoft AEG Rifles

"This is a nice looking head. O ring is suppose to have some kind of special quality. But truth is all I can say is I put it in my G&G UMP along with nothing else. I went from 310fps to 330-335 fps. Again all I did was change out the head.

"i brought this piston head with "ICS Aluminum Piston for Extreme Upgrade" (from Evike.com :D)
the rubber piece seemed like 1mm smaller then form the one that i had, so i just swapped it, other then that looks realllllly nice just like other guy sad increases performance ... well its better that it wont brake with m150 spring for sure..

5/5

"whats there to say? i have this piston head in two of my guns and i love everything about it even down to the sound it gives your gun.

pros:
lightweight and durable
ball bearings
makes your gun sound awesome

cons:
polycarb piston head might be preferable to some
it makes your gun sound different (it sounds like a sharp crack compared to the muffled sound of other piston heads which i think is cool but some others think is bad)
ive had to tighten it in one of my guns once after about a week of using it but ive had it in for about 9 months or so since then havent had to tighten it since

"Great seal and fits perfectly. Very nice piston head and for a great price.

"High quality piston head with a nice seal and a good bearing. This is working well in my G36 and I will most likely buy it again for future builds.

"This is a very nice piston head. It has a very high seal / precise o-ring on it making the air seal perfect. The bearing on it allows it to spin smoothly for minimum unnecessary friction. The alignment of it inside the cylinder and it's fit on the piston is perfect.

One of the most recommended piston head to get out of the few I tried. (Systema, Classic Army and Deep Fire. The bearing on this is more smooth than the Systema and it is stronger. I would not get the CA or deep fire ever again for they are bad quality.)

"It's a pretty good piston head, but I think the O-ring needs to be a little thicker. It doesn't quite provide the best air seal with my cylinder. I purchased a Guarder one of the same design and it gave me the best air seal.

"I purchased this for my bothers CM041 which had a very poor seal. When I installed this piston head the compression was no better. In that case I just decided to leave the stock piston head. After that I tried it in my AK and a JG AUG and found they were much better off without this piston head. I've had good experiences with other Matrix products (especially Matrix cylinder heads) so I thought this would be a good product too. Dissapointed in this piston head.
