Gun Sights

Upgrade target acquisition with GrabAGun’s Gun Sights aisle. From classic iron sights to fiber-optic and tritium night sets, each option is built for faster alignments, tighter groups, and rugged reliability in the field or on duty. Flip-up and fixed Magpul MBUS pairs snap to any MIL-STD rail, while combat-ready rear/front combos from Trijicon and AmeriGlo drop straight onto Glock, SIG, or M&P dovetails. Suppressor-height sets clear threaded barrels and slide-mounted optics, and high-visibility fiber rods from Williams glow bright on turkey guns and rimfire trainers alike.

Filter by platform—AR, AK, handgun, or shotgun—and compare blade heights, dot colors, and dovetail cuts right on the product page. All sights ship factory-sealed with hardened finishes and laser-cut indexes to hold zero against recoil and rough weather. Add backup irons for a red-dot build, grab a bead upgrade for your scattergun, or outfit a defensive pistol with glow-in-the-dark dots—then drop loaders, cleaning gear, and spare mags in the same cart. Flat-rate ammo shipping and fast processing keep checkout predictable, and Shoot Now Pay Later! financing lets you lock in upgrades today and train harder tomorrow. From weekend steel matches to midnight home-defense readiness, shooters nationwide trust GrabAGun for gun sights that stay bright, stay true, and stay ready.
