american tactical, about 600 bucks but you get interchangeable chokes, barrel selector, selective ejectors/extractors. And its pleasing to the eye and balanced well. Accepts Beretta/Benelli Mobile chokes
I have several higher end loopy 's, a Nightforce NXS. Arkens are just as good IMO and 1/3 the price.
