I want to build an inline that looks like the 9K32 "Strela" or the LAW. The only thing stopping me now is that the barrell diameter has to be same throughout the cannon including that chamber.s there anyway that I can build a powerful inline with the same pipe diameter throughout?

very very easy - If your tube is 4'10" long (correct for a Strela), simply stick a screw in the tube as a stopper aroud 3 and half feet away from the back, and seal up the back end. Not the most efficient of configurations but it should work.

edit: basically what you want is a narrower version of DR's basketball cannon

That means it stops the ammo from falling into the chaber right? On the [http://www.xonedesign.ro/fnxd/amc/]anti material canon[/url] it uses a bike pump...Is the AMC configuration better?
