I like my Mordax a lot. Need to shoot it more than I have so far.
I don't ever plan on using mine as a pistol. If I want to shoot a PCP pistol, I like my Manul best for that.
So as a short, foldable, handy carbine, I wasn't too worried about the length of the big honking Huma Mod 40 I put on the muzzle. Or the extra ~1/2" of LOP I get with the Magpul rubber butt pad on the stock.
My Sidewinder Compact, also in .22, is pretty loud from the action. I was pleasantly surprised that my Mordax was NOT. So that big mod allows the gun to be shot quietly and comfortably, with just a pfffut. I love it! Maybe just easier to moderate the sound since this gun produces a lot less power as compared to the Sidewinder?
I've just shot in my back yard, so I only fill to 250-260 bar and refill after each mag. I like that the gun gives me right around 800 fps with FX Atomic hollowpoints, even with that short little barrel. And the SubMOA barrel is very accurate. I think that the zero eye relief scope (MTC Viper) works really well in this application, providing plenty of magnification and a wide field of view, very comfortably.
It wouldn't bother me at all if these guns were semi-only, and lost the full auto. But it is fun once or twice, or when someone hasn't seen/shot the gun before.
I bought the gun pre-owned through AoA, and its operation has been flawless. I don't think that I've discovered anything about it which causes me to regret the purchase.
