Tangent Theta 3-15x50 Riflescope, Model TT315M - Gen3 XR - mRad

This is a highly sought after scope, as the Model TT315M offers the best optics in the World at a reduced price.  This model has a 30mm tube, as is very similar to the Premier scope, when they were produced.  The Gen2 XR reticle is widely used and admired by long distance shooters.

As with many Tangent Theta scopes, price is usually not the biggest driver, it is availability.  This scope is so popular, that we are most often back-ordered.  Please feel free to leave your email address to be notified, or contact our office about deposit options to guarantee a place in line.
