i just bought this yesterday after school. dropped by and picked this sucker up along with a prowin piston. i installed it later in the night at like 11. everything was very easy to put in. it was recommended by one of the guys to switch out the oring on the piston head as apparently it doesnt create a proper seal causing loss of pressure. anyways everything is a VERY snug fit. after replacing the oring with the original one the piston takes a large amount of force to manually push into the cylinder. the cylinder head sticks on nicely as well. i didnt use the piston it came with as it is supposedly only able to withstand up to a spring of 1 joule. so installation was a breeze and i reassembled everything. took it outside to shoot and i noticed it sounded alot better than the stock stuff. noticably quieter. only loud thing is the motor... so i shot a couple on semi. and then i went to full auto. i got a higher rof i think its from the lighter piston but im not sure. after shooting about a 40 rounds off. i heard the gb give off a nasty errr. so i immediately stopped shooting. i took it inside and checked it out. it sounded like the piston was stripped or something stripped. so i took everything apart and checked. nothing. then i noticed alot of bbs stuck in my silencer. so the blockage caused the air shot out from the nozzle to be pushed back causing improper cycling of the piston. lets say i was very relieved that i didnt just waste 20 dollars on a piston. to say the least this kit is amazing. great compression. everything looks like high quality parts. give it a give it a 10 outta 10
