I'm having trouble finding the following parts for my gun:

5" to 4" Converter
5" Threaded Cleanout
5" Threaded End Cap

Any suggestions?

No I have a 4" chamber but the end cap and other stuff are 1" bigger. Isn't that how most guns are? Also I found a 5" to 4" reducer on Amazon for $3 surprisingly enough.

I'll check out sprinkler.com. Thanks!

P.S.
Does it sound like I'm making my gun wrong?!?

I've seen diameter and schedule info on 5" pipe on Mcmaster, but they don't sell it (apart from 5" flanges, which are kind of useless without 5" pipe or fittings). As far as I can tell, 5" pipe is about as common as 3.5" pipe, which is to say practically non-existent.

If your chamber is 4", why don't you just buy some 4" fittings for it? They will be far easier to find and cheaper than 5" fittings.

I'm realizing that I'm retarded and you're right. Is 2.5" PVC hard to find? Fittings and piping?

You will more than likely have to get it offline. It's not a common part that is needed, let alone pressure rated (if you're using it on a pneumatic).

Yeah I'm in Texas. We have home depot and lowes here. Will they have it? Also my gun is combustion.

Are tennis balls worth shooting? Or should I do a 1.5" instead? Also does 2" or 1.5" potato "slug" shoot further? I would guess 2" cause it has more mass. What do you'll think?

do you have a irrigation specialty store around?? if so you can go there and get some cam locks so you can have interchangeable barrels and they will carry sdr21 1.5" which is golf ball barrel size and golf balls are fun to shoot
Yea, that's definitely going to get you at least a tazer.
