I have been doing a lot of reading and searching but it still seems to be a lot of apples and oranges. If anyone would be kind enough to pass along any info on whats best for the money I would appreciate it. I am basically looking at building a handy 300-400 yard and in carbine. Something that is just as handy clearing a building as going out to 300 yards or so. I have pretty much settle on a 16 inch barrel with flash hider just to avoid the paper work. Probably a aimpoint type sight. Rest is pretty much open. Really looking for the most cost effective parts that are still reliable.
