Is it worthwhile to upgrade a Leupold M 8 fixed power 6x36 or 8x40 AO to M 1 turrets or should I just stick to the friction dials and get a LR duplex instead? I’m not really a long range hunter but would like the option to shoot to 500 yards or so.
I tried to have Leupold install an LR Duplex in an 8x, and there was an issue - I don’t recall if the reticle wouldn’t physically work in that particular scope or if the subtensions would be way off...have had them tell me both on different scopes and I don’t recall which with the 8x. Anyway, the LR Duplex didn’t work properly with the 8x.
If you get M1s installed, there’s a chance the adjustments won’t be exactly MOA. I’ve had several and the exact amount of adjustment varied by scope. Just had to shoot and see. And the scope still could crap out, don't really trust them for serious dialing.
Long way of saying save your money, leave the Leupolds as they are, especially the old good ones that work correctly, and buy an SWFA 3-9.
