I bought a scope for a new rifle that had not come in yet. 4 weeks passed and finally my rifle showed up. Mounted the scope and find the scope defective, will not hold zero. Get in touch with seller, northern shipments a seller thru Amazon and they say toobad it's over 30 day return period. Explain to them the situation and still too bad for you. Get in touch with Amazon and their guarantee department and they say TOO BAD you have to keep the defective scope. I have been a good customer with Amazon and that's the way they treat you. Never buy from them again and will report this deal to every reveiw site I can find. Buyer beware of Amazon and northern shipments.
