Quite! If it shoots reliably it ought to be a good low cost alternative the the full bore version which in the new semi-auto version seems to have had some dramas.
I'd have gone over in much more detail, but i was covered in hydraulic oil most of the afternoon.
The heart of the action seems to be an adaptation of the AR-15 .22 conversion which isn't a bad thing. Magazines are stout. Barrel proper is not a "heavy" profile, but is more substantial than the .22rf clone of the MP-5. Generally nicer than the .22 MP-5s.
