Howdy, partner. Meet the Holosun ARO-MRS-GR — your new rifle-ridin’, target-punchin’, never-backin’-down green dot optic. This ain’t your granddad’s red dot. The ARO (Advanced Rifle Optic) takes everything folks loved about the classic 403 and 503 series and cranks it up with a bigger 22mm housing and a new 1.63” lower 1/3 co-witness mount made to ride flush with Holosun’s magnifiers.

What’s under the hood? A blazing bright green Super LED backed by Holosun’s Multi-Reticle System (MRS) – flip between a crisp 2 MOA dot, a 65 MOA circle, or run both for fast target work and tack-driver precision. With Shake Awake™, your optic naps when you do, then fires up the moment your rifle moves. Battery life? Try up to 50,000 hours. That’s over 5 years of green-dot glory from a single CR2032 cell.

This optic’s got grit. She’s built tough from aluminum with a hard MAO finish, waterproof to IP67 standards, and shrugging off 1000G of recoil like a bronc buster on rodeo night. Whether you’re patrolling the perimeter, clearing a hallway, or ringing steel from 100 yards out, this optic don’t flinch.
