I had a UTG on a Hogue stock...it required quite a bit of whittling and cutting of the fore-end to get it to fit. You have to profile the fore-end tip to match the shape of the original Ruger carbine stock, with barrel-band. IIRC, it also needed a thin strip shaved off the top edge of the barrel channel on both sides. That stock is gone...I now have the UTG on an original wood carbine stock reamed out for a bull barrel and like it very much. It comes with a bushing that is used with the original-profile barrel, and removed for use with a bull barrel. Not exactly military-grade hardware, but lots of fun and worth the price.
