I have the 1712 and I use the Leupold scope mentioned but it's boosted to an 18X40 power. I have solid steel (or whatever they are made of) millet angle loc rings and I'm a number of OZ's under weight. How much??? I forgot and if some one dosen't give you a more precise answer I can get it weighed.(I made wieght in 4 state matches this year) I will tell you this, I can leave the scope caps on and weigh in with a loaded mag and still be under. I think the digital scale says the rifle with scope and mag is at 8lbs/5 ozs. I do know there are 6 of us shooting this rig at my local club with various scopes and mounts from millet to BKL riser blocks and high rings and no one has any weight issuies.
Buy the rifle and scope mount it any way you want, should be good to go. Could be wrong but I haven't heard of anyone having a problem with that scope and making weight.
Sorry to ramble,
Geo
