I picked up a LSA 55 in .222 the other day--the first I have ever seen. It came out of an estate, and the youngest box of reloads in the guy's stash was dated 1995. The bore cleaned up perfectly; I have put a 6.5-20x Leupold on it for testing, but I am betting that it shoots sub .5 MOA. Too bad it is not a lefty.
