I thought about shrouding the whole barrel, but I'm still working on the mechanics of it.Something that crossed my mind that I would really enjoy doing is trimming the break back to where it's just at the end of the barrel and then porting the barrel just behind the break. Just 2 or 4 1/16" holes to let just a little pressure vent. Then I would build a sleeve to shroud the whole barrel, sealed at the back. The barrel would be light, look like a bull barrel, and it would work as a integral semi-(*^%.
