Weighing in at just over 1 oz., the Nikon P-Tactical Spur red-dot sight is shockproof, waterproof and maintains power from one CR1632 battery for up to 15,000 hours of continuous use. The unit features Nikon’s Trucolor lens coating, which is claimed to remove blue color tones within the viewing area. A 3-m.o.a. dot within the aluminum unit has 10 brightness settings—two of which are reserved for use with night vision optics. The exterior features a glare-reducing, matte black finish, and the unit contains a removable Picatinny rail mount. Price: $220. Contact: Nikon Inc.; (800) 645-6687; nikonsportoptics.com
