Optics & Sights

Top AR optics and sights from Sig Sauer, Holosun, Magpul and more.

A reflex sight and a solid pair of iron sights is what finishes off your custom AR build. Without it, your new black rifle or pistol is nothing more than a safe queen or wall hanger. We've partnered with three of the country's top optics makers - Sig, Holosun, and Magpul - to provide battle-ready backup irons and some of the highest quality reflex red dots you'll ever find.

 

Holosun Micro Red Dots for Rifles and Handguns

Holosun is a big name for two reasons: Quality and price. Their reflex sights sport anodized, mil-spec alloy aluminum housings with multi-coated lenses and easy MOA adjustments. Our staff, with personal experience handling Holosun optics downrange, agrees: Their optics provide some of the highest clarity, the best reticles, and the lightest and toughest units at a fraction of more expensive options from Aimpoint and EOTech. Check out their X2 MRS for your 1911 or Glock, or their MRS 2-MOA rifle red dot for your AR. Did we mention these units can run entirely on solar power?

 

Sig Sauer Red Dots for maximum accuracy

Sig Sauer needs no introduction. They've become a storied gunmaker whose handguns and rifles have seen service and combat for decades. Now they're broaching the red dot optics market with some truly high-quality but surprisingly affordable units. The Romeo5 is a hyper-accurate, compact reflex sight boasting no parallax error and up to 50,000 hours of battery life. Need some red dot action on your favorite Sig handgun or other piece? Check out the Romeo1 PRO, one of the smallest handgun optics on the market.

 

 Magpul BUIS Sights for your AR

Show up at the range with your AR's top rails sporting no back-up irons, and you might be laughed off the firing line. Trust us, you're going to want Magpul's BUIS sights, anyway: They're incredibly tough, compact, and affordable. Providing simply windage and elevation adjustments for a quick zero, they fold up and down with a flick of the wrist, locking into place without any tools.
