Step 6: Barrel (Final)
Can you tell that you weren't fired yet, that's because we really don't care what you think about. But we do care about results, so keep working.
Cut out three rings for the barrel end.
The first ring is a larger thicker ring for the rear of the barrel. Chamfer one side to the thickness of the second ring. The second and third rings are the same size but the third is chamfered to the front of the barrel.
Paint and fill to make them smooth and space them evenly on the extended barrel, then paint the whole lot with black spray paint.
(You can use a matte or gloss finish)
