Battle-ready optics and sights for your AR-type rifle, pistol, or handgun.

The sights you look through are just as important as the rounds you're sending downrange. After all, you won't get MOA groupings (or even hit paper) without a good red dot, scope, or at least some back-up irons. We've partnered with top makers like Sig Sauer, Magpul, and Holosun to afford a quality selection of compact, shock-proof, weatherproof, do-it-all red dots and reflex sights.

Quality AR Optics From Sig Sauer and Holosun

We chose these two optics makers for their ability to product compact, hyper-accurate red dots that can take a beating in all weather and conditions. The Romeo MSR from Sig Sauer affords shooters with an ultra-compact red dot sight that provides unlimited eye relief and zero parallax error. Twelve brightness settings are available - 10 for daytime and 2 for night vision. Over 20,000 hours of battery life is provided on a single CR1632. It's all topped off by an aircraft-grade aluminum housing that sports an IPX-7 waterproof rating.

Want unlimited red dot life? Grab the Holosun 2-MOA Solar Red Dot instead. It provides similar performance and features while also providing solar-powered operation if your battery ever dies. Included is a "Smart" brightness setting that can adjust automatically to your shooting conditions via the shock- and waterproof solar panel atop the optic's housing. It, too, features full waterproofing (IP67) with a one-piece aluminum housing and a precision optic ran by a single battery with up to 50,000 hours of performance, no solar required.

Quality Handgun Micro Red Dots

Want to trick out your completed, custom 80% 1911 or 80% GLOCK-compatible pistol? We've got you covered in the optics department here, too. We partnered with Sig and Holosun to bring you their lines of handgun red dots and sights, providing the same level of battle-rifle performance and power in units that barely take up any space on your slide. Check out the Sig Romeo1 PRO or the solar- and battery-operated Holosun X2 for your pistol.

Compact, Tough Backup Iron Sights

No AR's finished until you've got a set of reliable, no-batteries-needed backup iron sights (BUIS). We've collected some of the best and most affordable BUIS units from Magpul, and rugged mini flip-up sights, made from mil-spec aluminum alloy with a hardcoat anodized finish. These back-up irons will easily interface with your choice of red dot or optic, providing a simple "just-in-case" solution for sending shot groups downrange accurately.
