I quickly asked about that as well. They do make them in small runs. however, it will need to do a lot of stock work to make it fit. because the barrel is threaded on and doesnt use the vblock the dimensions are completely different. you wont be able to get a synthetic stock at all. it either has to be laminate or solid wood and you need to get a gunsmith to inlet and probably bed it for you (unless you are very handy and have the proper tools). its a whole other ballgame.
IMO there are many other factors which will impact the accuracy much more than going with a threaded receiver over standard. the first of which is obviously shooter skill followed by ammo. unless you are planning on shooting $0.50/shot match ammo you wont notice a difference in the slightest. going with a dlask barrel and receiver isnt like ruger standard. the tolerances are a lot tighter. just getting a standard barrel installed is a job in itself. the fit is so tight that even without the vblock installed you could probably fire off a few rounds before the barrel started coming loose. if you want to go that route and are ok with the price i would instead just order a kidd supergrade build from the US and have it imported into canada by irunguns. however, you will be more than satisfied by the non-threaded receiver.
