Don't skrimp on optics, buy once cry once! At 1000 yards you need proven repeatable adjustments and clear glass. That SIG is a fine rifle don't ruin it with sub par optics. Wait and save if you have to it will be worth it in the end. 750 doesn't go far these days, it can be done for that but save a little more and you'll thank me later. Most of us have been down the same road your on, I never use to think a nightforce or razor could possibly be worth that kinda money, I worked my way threw scopes from 500-1500 before I finally listened to what the experienced long range shooters were telling me, took me 2 years to get a nightforce, another year to get the razor, I lost a lot of money along the way on optics that didn't fit the bill, I fought my way threw competitions, struggeled for repeatable long range accuracy, then finally took the plunge and never looked back. I can't afford to put them on all my guns but it seems like they are the only 2 guns I shoot now at least for a couple more years. There are alot of great optics outthere, you know deep down inside what you really want. Good luck.
