Hopup Chamber Screw for WE Hi-Capa Series Airsoft Gas Magazine - Part #32

"also works on glock we hopups

"If you're someone who likes to modify your hop up/chamber for your airsoft pistol, these will strip QUICKLY. I've bought at least 10 and have gone through all of them. Why? Because if you wan to tighten them, they'll strip with little to no effort of trying to make sure they're tight, especially when using a c02 pistol and want to make sure they don't come loose on you. These would be better if they were torques or flat heads, something that would strip less easily.

Pro's:
They hold your hop up housing together

Con's:
they strip really easily and loosen up over time
