I recently acquired a .223 RPR and already had a Weaver T36 that I would like to mount on it. I would prefer to use Burris rings with the inserts, but the set of high ones I have will not allow the front of the scope to clear the rail. Would a .5 inch riser work well or should I just purchase new rings? If I need to purchase new rings or 1 piece mount, what would you suggest? I should mention that for now my range is limited to 200 yds. Thanks in advance for any suggestions.
