Holosun HE515GT-RD Black 1x20mm 2 MOA Red Dot/65 MOA Red Circle Multi Reticle Sight

The Holosun HE515GT-RD is a compact 20mm red dot sight built for shooters who want versatility without the bulk. This multi-reticle optic lets you toggle between a precise 2 MOA dot for tight shots and a 65 MOA circle dot for faster target acquisition—all with a button press. Whether you're running it on a rifle, pistol, or shotgun, the 515GT adapts to your shooting style and lighting conditions without compromise.

Built from CNC-machined titanium, this sight is tough enough for serious use while staying light enough to not slow you down. The parallax-free design means you can shoot from different eye positions without worrying about zero shift, and the streamlined housing keeps your sight picture clean. Holosun's Shake Awake technology automatically puts the optic to sleep when still and wakes it at the first movement—a battery-life game-changer that keeps your CR2032 running for up to five years. The flip-up lens covers are clear, removable, and don't obstruct your view when mounted, and the integrated kill flash cuts down glare for low-light work.

Shooters choosing the 515GT appreciate the straightforward push-button controls, the efficient LED that works in sun or shade, and the solar fail-safe that keeps the optic running even if the battery dies. It's a no-fuss red dot that rewards accuracy and speed in equal measure.

Frequently Asked Questions

What's the difference between the 2 MOA dot and 65 MOA circle reticle?

The 2 MOA dot gives you a tight, precise aiming point for precision shooting at distance. The 65 MOA circle is wider and better for faster target acquisition and shooting at closer range. You switch between them with a button press, so you can match your reticle to your shooting situation.

How long does the battery really last?

Holosun rates the CR2032 battery for up to 5 years of runtime. That life extends further thanks to Shake Awake technology, which powers down the optic when it's not moving and wakes it again at the first motion—you're not burning battery sitting on a shelf or in a safe.

What platforms can I mount this on?

The HE515GT-RD is a 20mm red dot and works with any standard 20mm rail system. You'll find it on AR-15s, AR-pistols, shotguns, AK variants with Picatinny rails, and other rifles and pistols equipped for 20mm optics.

Will this optic zero shift if I move my head around?

No. The HE515GT-RD is parallax-free, meaning your point of aim stays true regardless of your eye position behind the optic. You don't have to hunt for the exact cheek weld to stay zeroed.
