Everything you need to make every second count is available in one extremely versatile riflescope: the Mark 8 M5B1 scope. With an astonishing, 1.1-8x magnification range, shooters will no longer sacrifice precision for field of view. The illuminated front focal plane reticles subtend consistently at high and low magnification for the most accurate range estimating and range compensating available with today’s tactical reticle designs. Easily fine-tune your point of impact, while preventing accidental movement, with Auto-Locking Pinch and Turn adjustments. A 34mm maintube produces unparalleled windage and elevation adjustment travel, while the ability to bypass the zero-stop in the BDC dial makes zeroing a breeze.
