If you buy a Boyd's stock, take a real good look at it before you start fitting anything. I had one that was perfect, with no problems, but another had misalignment problems between the upper and lower inletting. Basically, the barreled receiver fit fine, and the magazine fit fine, but they were tilted in relation to each other so that the action screws could not be installed. A hint of problems to come is that the action screw holes in the stock were hogged out way oversize and off center. Unfortunately, I had already opened up the barrel channel for a huge barrel, and could not return it.
