I currently am just a target shooter. This will probably be my long distance rifle. I haven't made a final decision what it'll be used for as of yet.
I just like the challenge of working with my hands and building things. This is one of those things that I can truely say that I built it myself (more or less...).
In reguards to the adjustable/single shot style, my ADAMS AR15 has it, and was just throwing it out there as part of my considerations. To have one of these "hot rods" of either caliber in a single shot is kinda lame, but hey, to each their own. Variety is the spice of life, and I don't want to limit my available options.
Also I don't know what kind of, and how many options are out there right now.
