I had a difficult time getting a mount/rings combo for my 308 Win Striker that would both fit my scope (Burris 2-7X) and work well. I tried multiple combinations, including Leupold Quick-detatchable (Weaver style) base/rings (didn't fit as it needed extension rings they don't make for the Weaver style :roll: ) and Weaver extension mounts w/ Weaver rings (scope moved 1/16" every 12 shots ) before I finally sent it to SSK Industries for their T'SOB mount & rings. Then, their rings (med) weren't high enough. Ended up buying 3 Burris high Z-rings and used w/ the T'SOB. I've been satisfied w/ this set up. If I had it to do over again, I'd probably first try the Weaver 1 piece base (it has multiple slots in it) and 3 Burris Z-rings. Look at the dimensions of your scope very carefully before ordering your base/rings. Some scopes, especially a short one like the Burris 2-7X, don't allow you much room in which to place rings, especially if you're using more than 2 rings. Longer scopes, such as the Burris 3-9X and 3-12X, are easier to mount. For a 242, I'd think 2 rings would be sufficient. After using the Burris Signature rings to mount scopes on the last few Contender barrels, I've decided these are my favorite rings. Gary T.
