Whether it's "unfinished" or not depends on the goal I guess. If you intended to make a complete lever action blaster, then "unfinished" isn't too far off. If the objective was to prove the lever action concept, then it's finished.

In the grand scheme of things, I think it's unfinished. I mean, isn't the ultimate goal always something you can shoot someone with easily?

Anyway, to keep this from being a worthless post about semantics, I think to have the most fun with this, great ROF would be necessary. Something high capacity, so you can use the lever action over and over without fumbling with darts. Watching the way you fire it in the video, an RSCB looks like it would be extremely natural. The way you held it while using the lever already turned the barrel downward and shook it a bit, making reloading effortless.

I assume that the spring strength is causing you to prime it that way?

Are the spikes on the top integral to the design? I liked the concept, but it seems confusing and wonky to use in a battle. Not to ask too much, but could you post a video? Thanks.

I think he has a point. I mean, who could possibly guess why an unfinished, partially designed homemade would be confusing and "wonky" to use in a battle? You definitely need to post a video, because pictures and text clearly cannot convey the fact that it's unfinished and incomplete, making it unusable in the exact state shown.

I remember when people who were around for ~ 2 years could understand words.

Copper has an internal diameter that is too large for 99% of foam. It comes in 1/4" increments. Brass, on the other hand, comes in increments of 1/32", allowing a more custom fit for foam. Most foams fit either 17/32" or 9/16" brass.

If he asks why it can't be loose, that is because air will move around the dart. You need a comfortably tight fit for springers to build up pressure. Air guns should have loose barrels, but not so much that darts fall out, just for convenience reasons.

Copper is also pretty damn expensive.

Edit: Well, this post is pretty much pointless now, too late to the party. I'll leave it anyway.

You screwed yourself the moment you thought you had enough experience to mess with the innards of a Vulcan.

You're not plugging the pump, so don't even unscrew the shell. Just take a hacksaw/band saw/etc to the barrels, leave one inch stubs, remove the restrictive bits, and throw the CPVC in there. Sand down the inside of the stock barrels with a dremel if it doesn't fit.

I've never CPVC'd a 2k, but it can't be that much harder than the PETG ones I've done. 7 might take two hours, no biggie.
