How do you modify the CPS 4100?

Post by JCSoaker » Mon Apr 09, 2007 6:00 am

I have no idea how to modify a CPS 4100 to make it super powerful.
The red stopper prevents it from being opened and seperated into halves.

Any ideas?

For a list of modifications that are unique to certain water guns, check out each water gun's review page. Also, we had a thread about which modifications can be done to which water guns that you can check out. I'll just tell you which modifications can be done right now though to save you some time. In the future, please save us some time by getting the answer yourself. ;)

Some good modifications for the CPS 4100 include colossus, nozzle drilling, and the backpack modification. / Please read this before emailing or PMing me

Do not ask me water gun questions by email or PM. Please post the question at the forum. Private questions and suggestions are welcome by PM and email. Also, I do not sell or buy water guns online.

Hmm, I actually had a bit of trouble searching back when I had to open mine up for repairs.

The only solution is to saw of the red cap - it's glued on. Just take a metal saw of some type and start sawing at the red/gray seam.

Once you get over the shock of actually sawing off part of a CPS gun, you'll have fun :) . It was no choice for me, as the gun's trigger was broken anyway and the pressure chamber was full. I had nothing to lose by opening up the gun.

You probably have a Mark 2 CPS 4100, so do a trigger reinforcement before the trigger breaks. Trust me on this, if you have the Mk.2. It's going to break sometime.
