good piston head made of some durable type of polymer or plastic.
comes with a BETTER polished sliding washer system instead of the ball bearing washer that are prone to break under alot of stress or time.
Pros:
DURABLE, very consistent fps ratings, free spinning washer system in rear to make spring spin freely is effective (just grease or oil before installing) more durable than the ball bearing type on systema and prometheus. Durable plastic material shows no wear after inspecting 10,000 shots, High speed due to large tri porting, excellent price, performs just as well as systema and prometheus for cheaper.
Cons:
O ring should be changed to #14 hardware store buna o ring, but 90% of airsoft piston heads need this upgrade so its not really a con.
just recieved this piston head a few days ago, great product. the head is very sturdy and is kept in place by a allen-wrench type screw. the wieghts on the back are some type pf aluminum so it is not as heavy as it looks. the head is very strong(i accidentally stepped on mine witha pair of steel toe boots and it still works :D. the vents in the head also make for great compression, although i recommend getting a #14 O- Ring for it
Pros:
great durability
compression
2 free spinning washers allow for better spring flexability
Cons:
little on the heavy side for some
needs #14 O-ring
