does anyone have one of these and whats you opinion of it? I have my eye on this and a raptor mini in .25
In my opinion, the Skyhawk/P15 action is more suited to .177 or .22 calibers. It might be a little anemic for .25 caliber. I have a .177 Skyhawk that I used for FT most of last year, but I now have a JSAR .22 Raptor on order for long-range/high-power shooting.
The Skyhawk does have a few issues. Mine shot just OK from the factory. The factory barrel had some issues so I re-barreled mine with a LW poly barrel and it now shoots very good/great.
The factory Skyhawk magazines never fed smoothly, so I have only used the Skyhawk with the single shot tray. I plan on sticking with the Skyhawk for FT - I do like it. When I shot FT with my Marauder rifle, I always used magazines. Same for my Marauder pistol.
I was hoping that Diana/SPA would address the magazine issue since it has been a known issue for a long time. I won't buy any more of their magazines until they fix them, but I decided this morning to at least fix the two that I had. The axle hole in the center array piece of the magazine is slightly off center, so that would be a likely place to make an improvement, but it would not solve a more fundamental problem - off-center tolerance stack-up. The solution is simple but it does require a new housing or modification to the housing. The torsion spring holds the pellet against the side of the stop, not at the center of the stop. Apparently, the designer did not take that into account when designing the Skyhawk magazines. I made a new housing with a 2 degree rotation of the stop to take up the tolerance. It now feeds very smoothly.

Really nice work. Must have taken some time to get all the measurements and design the 3D math. What material did you print it out of? I'm a bit concerned using PLA or even PETG because of how it softens in heat...which can happen if you leave the gun in the back of a car.
The Umarex Gauntlet has a similar issue with it's pellet door. It isn't quite as bad on the pellets because of the larger diameter lead in the breech. It causes more of a problem with the probe o-rings which scrape on the misaligned holes and shear off...causing blowby and allowing the bolt handle to flop around.
