I own over 50 airguns and rifles. I use a Laserlyte bore sight to initially sight the rifle. They make a sight for .177 to .22 Cal and a .22 to 50 Cal sight. It fits in the end of the barrel. Make sure it's snug when you adjust it and remember to remove it before you fire the rifle. see http://www.laserlyte.com/Laser_Bore_Sighter/LBS-1722-140/index.html

Yes, you can mount a scope on a Remington 582 .22 cal. rifle. You will probably need to take off the plastic rear sight. And more than likely you will need high bases if you put on a 1" diameter scope.
I believe this rifle was imported by Excam. Look on left side of barrel below the rear sight. Is your rifle a semi-auto, take down? I am looking for a magazine for this rifle. Thanks. Wayne Bailey
