Questions & Answers
Will this fit my glock 40 Gen 4? Manufacturer Answer

The TRYBE Optics Micro Red Dot is cut for the RMSc optic footprint. The variance among different pistols or even the same models can vary widely. OEM documentation is the best source to ensure a proper match. That said, if the firearm does not have the RMSc footprint, then the optic may still fit, but it would require an adapter plate that converts the footprint found on the firearm to the RMSc.

will this fit your Glock 17 trybe defense slide? Manufacturer Answer

TRYBE Glock 17 slides are offered with 4 different optic cut variations. The only cut that would accept this optic is the DeltaPoint Pro cut. However, while the optic will fit, it will not fill the entirety of the optic cut since it was designed for slimline pistols, not full size/compact pistols such as the Glock 17. I would recommend emailing us at Techsales@opticsplanet.com and letting us know which specific model slide you have, that way we can more accurately recommend direct fit optics to your slide.

Nice sight by Ran, Verified Owner, January 11, 2025
This micro red dot was easy to install and looks great. Nice clean low profile lines fit great in the holster and zero this thing in was a breeze. The price point made this little sight too attractive to pass up on. I fully recommend this sight

Dropped and Chipped Glass by Jacob S, Verified Owner, April 9, 2025
The red dot was easy to mount and get zeroed. It looks good on the Taurus GX4XL. But while performing maintenance on my weapon I dropped the slide and it landed on the corner of the red dot. There's no physical damage to the outside frame, but to my ...

Great Red Dot by EvoStevo, Verified Owner, March 13, 2026
I bought this because I was looking for a more budget minded dot to just put on a 22 pistol. I am extremely impressed. It’s great quality all around and has held zero after many hundred rounds. I wasn’t expecting it to be as great as it is but I’d bu...

Product Info for TRYBE Optics 1x21mm Micro Advanced Ruggedized Optic Red Dot Sight, RMSc Footprint

The TRYBE Optics 1x21mm Advanced Ruggedized Optic (ARO) Micro red dot sights have been ruggedized to withstand the violence of the fastest velocity pistol slides for a lifetime of dependable use. Our large fully multicoated window allows for an excellent field of view and maximum situational awareness from the draw or on the move, and our crisp red 3 MOA dot is the perfect size for precision work as well as providing an intense aiming point when speed is needed for defensive duties on narrow-slide primary or backup pistols. Light transmission is unparalleled due to high-tech glare-reducing and anti-scratch coatings that protect from damage as well as making cleaning easy. Oil and dirt wipe right off. Powerful daylight bright dot means a reliable aiming point no matter the time of day or target reflectivity.image

TRYBE ARO Micro has an RMSc footprint and low base height, allowing the use of factory height iron sights for cowitness, so you can ditch the higher sights that obscure vision as required on most other pistol-suitable micro sights. ARO Micro weighs just over half an ounce, so it will never interfere with slide velocity or pistol functionality.

Digital operation means easy intensity adjustments which are sleek and streamlined against your body when carried. Modern, precise W&E adjustments nuts do not require additional lock nuts to hold zero. Adjustments are accurate and reliable.

AutoLive motion activation immediately illuminates your dot, ensuring your sight is always ready for action. Standby mode activates after 2 minutes without movement to conserve battery life. Up to 40,000 hours of battery life when constant on at medium power.

Our TRYBE Optics ARO Micro sight is ruggedized, sleek, powerful, clear, attractive, and ready to mount on all your most important EDC defensive pistols. ARO rivals any sight on the market and provides pride of ownership and battle-hardened durability you can count on when things go South.
