Nice Scopes - Burris has been good to me over the years / B-Plex is for distance shooting - nice. Burris 3-9x40 B-Plex Mat ...... take a look
3-9 because you can't shoot what you can't see.
If you trade the rifle - keep the scope.
Burris Sig Rings with Inserts for me.
~~~~~~~~~~~~~~~~~~~~~~
Can not go cheap on a scope, rings or mount. Movement & Parallax - both make your rifle shoot like a scattergun even with you doing things perfect / has driven many good riflemen nuts.
