Light Optimization Profile gives you the low-light performance advantages of a large objective riflescope, without the high mount. The 50mm VX-L mounts like a 36mm riflescope, yet delivers 48.6 percent more Total Light Throughout (TLT)! The lower mount also gives your rifle better balance, and the quick accurate aiming that comes with a low-mount cheekweld.
