I just picked up a SIG 522. I got a Bushnell 3-9x40 scope for it for $80. I figured that was about the right price for that rifle. All i can say is this thing is a damn tack driver. I'm not sure folks really call rim fire's tack drivers, but i am grouping 25 rd's in a 2.5" circle @ 150 yards.
I have one question though. i know the SIG 522 platform is still relatively new, but does anyone out there make aftermarket accessories for them like the 556? I know at least most 556 parts will fit the 522, but they are usually expensive. I'd like to hear from anyone who has found some aftermarket stuff for their 522
