I had some smith work done on my .300 win also had a sightron scope installed while there. I got the rifle back and had some scope questions so I called Sightron. In the conversation I learned that the allen wrench(supplied by Sightron)wasn't in the box. Wrench is for the target turrets. They promptly shipped me two out right away. I got them yesterday. They were great to deal with. The scope looks great I hope to test it tonight.
