Just got a .45 Hawken w/ a Tasco replica brass scope on it, just wondering if any of you guys have ever had one of these brass scopes and how it performed? Scope is 32 1/2" long and 3/4" dia. fixed 4x. Windage adjustments made via a screw assembly on the rear mount, elevation is adjusted by shimming under the front mount. Previous owner said he never got a chance to play around with it. Thanks for any input guys.
