The MTC Mamba UltraLite features a 25mm/1 inch tube which helps shave down some of the weight. First-rate multi-coated lenses that help light transmission perform as if it were one of the wider body tubes! Other than the MTC Mamba UltraLite's weight advantage, it incorporates some other great features, convenient magnifier, mil-dot reticle, semi-target turrets and flip-up covers.
