"I picked this piston head up for a budget DMR build i was doing. From the previous review i thought it would be well worth buying, however after receiving this part I can say with certainty that it is NOT. The part is CNC'd aluminum and has a nice attractive blue anodized finish, it appears to be of a good design and made well. The first problem i noted was that the main o-ring is 3mm too thin for the o-ring channel of the piston. This resulted in abysmal air seal an very poor fitment in the cylinder. The second problem i noted was that once i had gone out and gotten an o-ring that fit appropriately, the head created a vacuum that jammed up the gun. So it stands to say that either you deal with awful compression, or suffer through jams. If you want a budget DMR build i would suggest looking elsewhere, this part will only result in a headache.

"This thing is awesome. Double o-ring design gave my DMR build incredible compression. With an m130 spring my gun is shooting 430fps with .30g bbs with this piston head. Not even kidding. Great piston head at an incredible price.

My DMR build: Custom built SL9. Matrix high-torque motor, G&P high-torque steel CNC gears, Matrix aluminum piston, Matrix aluminum ball bearing spring guide. Matrix m130 spring, ASG ultimate aluminum cylinder head, non-ported cylinder. 6.01 JBU inner barrel (509mm), Mad Bull bucking. Runs off a 7.4v lipo, motor never even warms up. Not really pertinent to the review, but I felt I should share.

For a DMR build on a budget, this piston head is perfect. It's a bit of a tight fit in the cylinder, so lube accordingly.
