Colt Launches Its First Family of Red Dot Optics

Last updated July 2026 · By Nick Hall, covers optics and red dot sights for USA Gun Shop

Quick take: On June 30, 2026, Colt launched its first-ever line of electro-optics through a new division, Colt Electro Optics, based in Michigan. The debut family covers three red dot sights and a flip-to-side magnifier, all designed and assembled in the USA. It is a notable move: one of America’s oldest gunmakers is now competing head-on with established optics brands like Aimpoint, Trijicon, Holosun, and Sig.

• What it is: Colt’s first optics family — three red dot sights plus a magnifier — sold under the new Colt Electro Optics banner.
• Key detail: All three optics are designed and assembled in Michigan, USA.
• Specs: MRS-1 closed-emitter pistol red dot (1.85 in long, 2 oz, 3 MOA dot, ACRO footprint, 7075-T6 aluminum, $428); CSQ-1 rifle red dot with a large square window and multi-reticle system ($824); C3X-1 compact 3x flip-to-side magnifier (2.72 in long, 85mm eye relief, $604).
• Who it’s for: Pistol carriers, AR-15 shooters, and anyone who wants a red dot from a legacy American brand.

Colt steps into the optics business

For a company best known for the 1911 and the AR-15 platform, building optics is new territory. Colt has spent more than a century and a half making firearms, but until now it left the glass and electronics to specialist companies. That changed on June 30, 2026, when the brand introduced its first family of electro-optics through a dedicated arm called Colt Electro Optics, headquartered in Michigan.

The launch lineup is deliberately focused rather than sprawling: three red dot sights and a single magnifier. A red dot, for anyone new to the term, is an electronic sight that projects an illuminated aiming point onto a lens so you can keep both eyes open and put the dot on target — no lining up front and rear iron sights required. Colt is covering the two most common places shooters mount one, the pistol and the rifle, and adding a magnifier to stretch a rifle red dot’s reach.

MRS-1: a closed-emitter pistol red dot

The MRS-1 is Colt’s pistol-mounted red dot, and it uses a closed-emitter design. That matters for a carry optic. In an open-emitter sight, the LED that makes the dot fires across an exposed gap, where lint, rain, or snow can block it. A closed-emitter unit like the MRS-1 seals the electronics behind glass on both sides, so the dot stays visible in conditions that can wash out cheaper designs.

The MRS-1 measures 1.85 inches long, weighs 2 ounces, and puts a 3 MOA dot on target — a middle-of-the-road dot size that balances precision with fast target acquisition. It rides on the widely used ACRO footprint and is built from 7075-T6 aluminum, an aerospace-grade alloy known for its strength-to-weight ratio. MSRP is $428.

CSQ-1 and C3X-1: the rifle setup

For long guns, Colt offers the CSQ-1 red dot and the C3X-1 magnifier as a two-piece rifle package. The CSQ-1 is built around a large square window, which gives the shooter a wide, uncluttered field of view, and it runs a multi-reticle system — letting you switch between more than one aiming reticle rather than being locked to a single dot. MSRP on the CSQ-1 is $824.

The C3X-1 is a compact 3x flip-to-side magnifier that sits behind the red dot and swings out of the way when you don’t need it. At 2.72 inches long with 85mm of eye relief — the distance your eye can sit from the glass and still see a full image — it is meant to add reach for longer shots without permanently narrowing your close-range view. It carries a $604 MSRP. Shooters building an AR can compare options in our 10 best AR-15 red dot sights roundup.

Why this launch matters

Colt is walking into one of the most crowded corners of the gun-accessory market. Red dots are dominated by names like Aimpoint, Trijicon, Holosun, and Sig, each with deep catalogs and loyal followings. Breaking in means Colt has to convince buyers its glass can stand next to companies that have done nothing but build optics for years.

What Colt brings is brand weight and a made-in-America story — all three optics are designed and assembled in Michigan, a selling point in a category where a lot of product is built overseas. Whether the MRS-1, CSQ-1, and C3X-1 earn their asking prices will come down to real-world durability and how the dots hold zero, and that will take hands-on testing to judge.
