Didn't the Prism barrels get cloudy pretty quickly?

The main barrel tube would have a 1" OD and a 3/4 ID throughout. Insert would have the ID you want and a 3/4" or slightly larger (not sure what threads you're cutting) OD to fit snug. Can have it run just a few inches down the bore.
Otherwise treat it like a Carbon fiber barrel. Aluminum back /polycarbonate front. Rear is control bore, 1" OD stock, main barrel is 11/16 ID by anything with can find <1" OD.
bore 1" stock to accept polycarbonate front, thread for marker threads on opposite end.

We have a local here who made up a couple...can't remember if they were full barrels or just tips. They were EXTREMELY quiet, but they clouded up really fast, like one day of x-ball fast.

Huh, I wonder why. They would certainly be interesting to see!
skibbo - Sounds like a good idea. I may well nick it.

Blame the new guy........
Have you tried contacting Bayer directly about their poly-carbonate (Makrolon)? I found them incredibly helpful in past production. At one point in time they were producing poly carbonate tubing for the food industry. I have vacuum molded poly carbonate, works well as long as you pre-cook it to avoid bubbles forming during molding.

The clouding would be due to fine scratches, if you look at poly carbonate wrong it scratches, unless it has a scratch resistant coating.

And then the problem with polycarbonate after it scratches is that they tend to propagate and cause failure I have a love/hate relationship with polycarbonate as a material.
