Modern Full auto PCPs

Been a while since I was into PCPs, now I see things like selective fire PCPs shooting pellets instead of just 4.5mm steel BBs.

Is this just iterations of the Huben full auto PCP? Hows the main mechanism work?

Look who's still active
The Mordax is "hammerless", my understanding is that the internals are very close to the
Huben

Figured so! I found some animations for the Huben but I'm sure you have a better understanding of it than me? The Huben seems to not have a bolt nor nozzle? Just oring seal on both sides of the mag?

Correct, it fires directly from the magazine. In fact one difference between the Mordax and the Huben is that the former has a removable magazine, reportedly this leads to air loss on firing because it does not seal as well.

Oh so Huben uses a fixed magazine? So much for pellet chambering depth and such. 2k dollars for a plinker lol
Came across your full auto blow back 4.5bb gun on GTA, I suppose that can be refined into a selective fire version with a more complex trigger group. What's the power you were getting? And how many shoots per fill?

I've seen mixed reports on accuracy, some people are getting good results.

Indeed, and if you want something ready-made there are plenty of paintball marker trigger groups that would do the job just fine.

I never measured shots per fill but it was certainly more economical with air than a BBMG
Velocity was limited to below 500 fps for legal reasons but it was capable of much more. Need to make a larger caliber variation at some point.
