Absolutely! Just need a "U" Cylinder and "U" trig to have complete "U" build! Maybe the cylinder is made from 17-4PH or titanium with the end welded on. Possibly with an "exposed hammer" pin to tell if gun is cocked. Maybe do something similar with the "U" trigger. Maybe with a magnet similar to the "M" trigger but prettied up.

Well I found a way to cut the length of the assembly in half. It's back to just slightly longer than most normal cylinder heads. The downside though is that I don't think I can fit the adjustable length nozzle in the shorter design. So basically I have 2 versions: one short non-adjustable length version, and one fully adjustable version. The benefit of the shorter assembly is just more swept air volume in the cylinder.

I also was able to bore out the nozzle ID on both variants pretty considerably, so that will help with energy output as well.

Even with the lower energy output of the current setup, the shot to shot consistency is pretty outstanding. Better than any setup I've had before. Even with lighter bbs it shoots basically the exact same trajectory every shot.

I'm not in the position to do proper testing of things, but I'd certainly be a customer!

Also, it'd be cool if ya took a mm top and added a rubber damper to minimize sound/vibration and wear between the front of the chamber and the cylinder head. Technically that's also a way to adjust the cylinder head length, just adding multiple/thicker dampers.

Took a while, but here's the updated one actually made. Now I'm just waiting on the seals and spring to show up later this week so I can see if it works.

Oh also, I finally figured out the threading. It fits all cylinders I own perfectly now.

That's pretty cool, almost like a regular cylinder head in terms of volume reduction.

If your results are good then maybe I'll try to make a variation that is compatible with my Wolverine BOLT, but I think it will be quite tricky.
Until then, I look forward to your outcomes.

Well the springs I'm using ended up being just slightly smaller in diameter than their drawing, so they are a little tight inside the assembly. Though I was able to grind a small amount off the spring to fix the fitment. Otherwise, everything went together really well.

This updated design is now my highest output (energy wise) and most consistent nozzle I own.

Time for some more pics.

Full cylinder setup:




This shows the amount of distance the nozzle is adjusting at the end of the stroke. Picture is take just when the nozzle base butts up against the chamber. The rest of the cylinder stroke will be pushed against the nozzle return spring, but the nozzle placement in the hop up chamber remains the same throughout the whole stroke.

I mean sure, lol.

If anyone wants one send me a message. It will probably be in the $120-$130 range.

If you did a bulk buy, could you get that price down?

Yes, though probably not a huge amount.
