Heya Parks,, Thanks for the reply!! Already has 2 coats of primer,,& yes Im gonna paint it flat black!! Yes the main tube is PVC,, the end cap is Poplar,, the "thread end" is Brazilian Cherry,, VERY HARD wood!! The sleeve is copper tubing drilled to fit perfectly snug on the Disco/Crosman Brl. Epoxy holds everything together. Shure takes ALOT of work to alighn everything just right!! I have it down pat now. After ALOT of final sanding & paint,, the last step is to epoxy it to the brl. permanently. This is a CRUCIAL step,, as final alighnment is critical!! I have made a few of these types of muzzle breaks now & can assure you,, the final step is of the utmost importance,, you only get one shot at it. Unlike "Profesionally Made" breaks with only grub screws holding them on,,If I mess up,, the break will be destroyed completly if I decide to remove it!! Trust me, been there!! (Just wood splinters & epoxy left on the end of the brl.!!) Course,, I do have a spare brl. for my Discovery if I mess up!!LOL!! Tim.
