I recently had a bad experience regarding their "Lifetime Guarantee" and likely will never buy another because of it. The problem comes when the model one has fails and it has been discontinued. THEN one must buy or pay the difference between that scope and some other model with dissimilar features, etc. Not good for the consumer, IMHO.
We are in trouble with scopes and scope makers, in my opinion. One leading brand no longer accepts warranty and apparently has turned their back, having been acquired by another company and there is no place now to buy a pure 6X competition scope that is what we traditionally knew. The TACTICAL lads have run us out of consideration I guess.
