"Very well made. It fits perfectly and functions flawlessly along with my other angel custom parts. It comes with different o-rings, an allen wrench, and tabs for where the pump pushes on the piston for the CYMA 870. (the CYMA 870 cylinder is a slightly smaller diameter than a tm design and the piston is slightly different) I would highly recommend you pick up some locktite as the piston arms are held in by tiny screws (this is what the allen wrench is for) and so are the tabs. The piston heads seem to get a pretty good air seal in the cylinders. I can't vouch for any fps increase or decrease as I dont have a chrono but my range appears to be about the same. overall I'd recommend it, its well made, won't break with stronger springs, and should increase reliability if nothing else.

"weighed original piece ..was 25 grams..the angel custom is 51 grams...i swiss chessed some of it 46 grams..i had to sorbo the inside of the tri cyinders..was shooting 325fps..the new set-up is at 300fps..when i weighed them i already knew i was gonna lose a little fps with the angel cutom being has pdi piston heads for the trishot and 5 different inner barrel sizes but they only fit in the marui hop up unit..they will be a very tight squeeze in a cyma,clone,or a fabarm trishot
