Hop up bearing KWC USP 45.
 

Sorry for title, KSC USP .45, Ok so im having trouble finding this tiny ball bearing. Checked redwolf, and many other sites and they only have the part for the G17. I dont know if that will work or not. Anyone know where I could find one of these, or have a extra one for sale?

I lost mine too. I am not even shure if the gun had one istalled in the first place...just use something else instead. I put a round link from a dogtag chain into the chamber. You can also take a tour throu your lokal hardware store..maybe they can provide you with a ballbearing that fits.

I have the same problem, try getting a 3mm metal ball. Tirador once sent me a replacement ball but it's too small and has no effect. I've also work half good fixup with a hopup nod from an AEG and with roll of electric tape.

The problem with this hopup system is that it's non-adjustable. If the ball isn't the perfect size, you'll end up have either too much or not enough hop effect.

...another reason why I now only trust Marui when it come to gbb.

Good luck

My USP's hopup is most definitely adjustable.

I lost that ball from my KSC G17 as well. I made my own with a drop of solder. Works fucking awesome. My Glock will outrange many AEGs.

How do you adjust it?

The gun comes with a tool you stick through the breach and turn.

KSC guns defiantly have adjustable hopup. and the beauty of it is they stay adjusted, rather than the TM system of little dials and wheels and un-do over time.

Damn you Amos!

Hopup goes where?
 

I also made my own ball. I get alot more effect than I did without it, obviously, but it doesn't seem adjustable. It might be that it's too small but I think I put it back together wrong. The exploded print isn't much help so I was hoping maybe someone here could explain to me what goes where. (A bit of work, but I'd really appreciate it).

Thanks
