Sturdy, gas-purged, one-piece 1" tubes house superior optics and are waterproof, shockproof and fogproof. The fully multicoated lenses deliver outstanding image clarity and brightness, and exterior lenses have an extra-hard coating to guard against scratches. The 1.5-5 model (shown) has short, capped turrets. The 3-9 and 3.5-10 models have tall tactical turrets that can be re-set to zero with a wrench. Exposed turrets have no caps to lose and easy-to-use, return-to-zero capability. Precise windage and elevation adjustment. First-focal-plane mil-dot reticles.
