Wrench holster? :roll: Assume for opening the clean-out....

Your paint job effort is ruined by the duct tape wrap...why the duct tape wrap? A spray and pray combustion is not going to breech a 3" sched 40 chamber.

However, good job with the detachable breech loadable barrels. Welcome to Spudfiles.

breech is on the back of the barrel. to put it another way it is a way to load a projectile without a ram rod.

I meant breech in the verb form, not the noun. Perhaps I should word it differently....It won't blow up a 3" sched 40 chamber.....

Hey SF, "to breech" in english, is also a verb, which means to break through or overcome something. You are obviously familiar with the noun version of it.

Nice job for your first attempt at a combustion. Nice little spray n pray.

But like starman said, that duct tape just ruins the whole paint job. I would suggest hose clamps. Strong, sleek and reliable.
