HELP cant find right parts need anyother way to make it

[brettdotcom14]

sorry for making so many threads lately but i need help

ok this is what i wanna do:

4" x10" chamber

and interchangeable barrels

2 1/2...1 1/2 and 3/4

so i was going to have the chamber reduce to 2 1/2 then put a little 2 1/2 pvc pipe to a female adaptor then have a male adaptor on each barrel, but i cant find a reducer that goes from 2 1/2 to 1 1/2 or 3/4. so does any1 have any other ideas on how to make this?


actually i know how i could do it but i dont know if it would work right.

i was thinking going from a 4" chamber reduced to 2" then alittle section of 2" pipe to 2 1/2?

is it ok for me to go small to big or will i lose power?

its fine to go from 2"-2.5", i assume you're going to have a 4"-2" reducer and then a piece of 2" then a 2" female adapter, and have 2" males aon all your barrels, thats fine, but i think the 3/4" will be too small to give good performance from a 4" chamber
