I have a primary arms slx 1-8 it's relatively new i got it replaced with warranty about a year ago and have only used it maybe twice since then. I painted it to match my rifle,zeroed it and it's pretty much sat in the safe. It's in an aero mount, warranty travels on to the new owner as far as i understand but you may have to look into that a little more. For more pics/details shoot me a message here or at dobby937 at protonmail dot com.
