One thing you may find with the SR22 as so many of the members that particpate in the rimfire section, myself included is that the SR platform grows old really fast. its a great looking piece but at the end of the day atleast for myself, liking to hit my targets at 150-300 yards I quickly sold my heavily modified SR and opted to build a more suitable bench rest style rifle using a DAR22 as my base still wanting to stay in the 10/22 world.
edit, my point just made
now of course I followed his old thread and part of that accuracy in my opion would be the fact that he was running a red dot and not a high powered scope. but really who wants an AR syle with a big target scope hanging off it.
