This is a project I started concept art for in 2019, but never actually started work on until May of this year.

 

This blaster works via a front-primed plunger tube & plunger, with a bent barrel and sealed end that redirects air to shoot out of the stock 1995 Crossbow's barrel area. I used a widened Kronos catch with a 2nd catch spring, and a lever/linkage bar system to activate the catch. The linkage bar goes back to a polycarb trigger.

 

This blaster is getting ~150 fps out of an 8 inch CPVC barrel with 2/3 of a [k25].

 

If (when) I do this mod again, I will most likely use a Rainbow catch to use a [k26], perhaps a wider plunger tube, and probably integrate a brass breech onto the top (maybe with a 3d printed cover/casing/spacer?) instead of just a 1/2in PVC/CPVC coupler.

Nice and old school. What stop the plunger from hitting the end of the tube when you fire? Anything?

Nope. Couldn't come up with a backstop other than a foam buffer, but I ran out of foam. So there's just nothing. Hasn't been a problem so far though!

I wonder if you could come up with some sort of pully systems, so that it could be a pump to prime?

I am actually separately working on (brainstorming right now) a pump action 95 Crossbow, but it won't be this front-tube design. It will be a standard back-prime with priming bars internal (external if I can't make them fit) that go to a loop around the priming bar at the back. Still brainstorming though.

Brilliant idea that allow you to use the original bore-above-plunger setup without the tube-related losses.
