Bought .25 compact semi-auto with PCP only suppressor, several months ago.
Build quality was acceptable I'm a machinist and picky. Equivalent to high-quality for china parts, similar to Evanix build quality. Sear design is a backward paintball semi mechanism, functional, and built solid. (elongated pivot hole in trigger instead of in sear, works fine and has added benefit of no vibration as in old paintball designs). Some screws were loose, tightened them. I thought I had a problem with the bipod rail but looking at pictures that must have been something else since it doesn't seem to have a bipod rail and I no longer have the gun.
Consistent velocity and pretty good accuracy only fired 3-4 mags.
Hammer slides on a central rod (great design no hammer tilt or spring binding) and activates the valve that parallel but below the hammer centerline (like Logun MKII)
The sound was acceptable but louder than my buddy would like but he makes and refines hair curler LDC's for all his toys and has higher standards for sound than I do.
The semi-auto mechanism is based on a piston in the shroud that slides on the barrel. Probably over gassed for reliability as it has rubber bumpers at both ends of travel near the cocking handle. If you remove the suppressor it will still function reliably but will get much less air for the recocking, probably the reason for over-gassing.
The magazine is similar to Marauder but has a clearance slot for the rod that re-recocks the action. If Marauder magazines fit you could modify them (they do not). Uses a magnet retention system for the magazines, would probably work well with a little refinement either on their part or the purchaser.
I called about adding a reg to be able to use the bottle a full 4500 psi. They said the semi's don't work with a reg. I disagree, I have no issues with regulated semi's of which I have several. I do think that it was their way to say their plenum is too small, did not verify as I was returning the gun.
The bottle was smaller than advertised and it was shooting 800 fps, not 950 as advertised (probably a typo due to many eBay listings and purchasing the compact vs the full size). This caused the return.
I hope this helps someone make a purchasing decision.
Cheers,
