Poseidon Striker Hop Up Chamber Kit w/ Air Cushion Inner Barrel for ISSC M22, SAI BLU, Lonewolf, & Compatible Airsoft Gas Blowback Pistols
(Length: 84mm)

"Worked beautifully on a WE ISSC M22, though the sides of the hop up unit needed a bit of sanding to fit. Took all of 30s and I was set. I also got the 97mm barrel on accident but hey it's dead accurate with .25s out to 150 ft and hitting man sized targets at 200 ft so I can't complain much more than that.

"I love this hop up assembly. It allows my We G18 to shoot precisely at a 200 ft range.

"One and done drop in

Generally, WE Glock hop ups are good on their own, with the only mods being needed generally being the inner barrel, bucking and the hop wheel

This one however makes it more convenient to adjust hop with clicks, also the Poseidon design helps with accuracy, but has better accuracy with the bucking being changed for a maple leaf one.

I was able to get .32s (which are the heaviest BBs you can use in a standard airsoft gun before getting into sniper bbs) to hop perfectly.
