I have Talley extra low on a Glenfield model 30 with a VX3 1.5X5 and also a 336=A with a 2X-7X in Talley extra lows with no touching the rear sight issues. If your sope is 40 MM or larger you might be well served with med height rings. The Talley rings kept the weight off the 336 rifles as compared to another scope base/ring options.
