The WS-MCR in my opinion is the better of the two rifles. Both will shoot equally well, however the WS-MCR has some extra nice aspects that I appreciate.
That being said you won't go wrong with a WK-180C either.
Both rifles had less than ideal starts, including 3D-printed parts, very sharp machining edges, ultra-cheap cam pins, snapping pistons/cocking handles and castle nuts that hadn't been staked well (I've listed all the issues I recall, I am not saying both rifles had all of them it's a joint list)
This was in part caused by initially a very low price point ($1000 for the original WK180C), and later by both price pressure and a very significant pressure to manufacture as many as possible as the political climate was (and remains) high risk to semi-auto firearms manufacturers.
The teething issues caused by these factors have largely been overcome. Prices have risen to the point where higher quality materials are likely in use, enough time has passed for circa 19,000 rifles (combined WK180C + WS-MCR) to be made and competition in the form of new receivers, after market spare parts and comparable rifles such as the J180 and the NDS 18SC has put the pressure on to make things better. In addition thousands of Type 97s, Type 81s, IWI X95s, Kel-Tecs and far more have been imported. The WK180C and WS-MCR now have a much more limited window of time in which they are the sole Canadian producers of modern sporting rifles.
Kodiak the manufacturer of the WK180C offers excellent customer service. I can't comment on Wolverine's customer service for the WS-MCR as I don't own one, however my warranty claim with them is now running on 1 year with no end in sight and emails no longer being responded to. I can't comment as to whether that is representative of Wolverine and I think others should chime in with their experiences to give a more balanced view.
