Unlike some other brands, we don’t use the word “value” as a euphemism for “junk”. Our CALF series red dots are perfect for the budget-conscious with reliability on par with more expensive optics. We take the time to test every product we send out to ensure you are receiving the best quality, period. The CALF X1 is optimized for full-size carry pistols as it is made of compact and rugged aircraft-grade aluminum. It features MOTAC (Motion Activated Illumination), the red dot will activate as soon as it senses movement, and go to sleep automatically when left still for 5 minutes. If you are looking for a new red dot for daily carry, you can't go wrong with the CALF X1. The CALF X1 will NOT fit guns using the RMSc(407k/507k) footprint, including the Canik TP9 Elite or SC/Hellcat/Ruger Max-9. If you are unsure what footprint your pistol uses, contact the manufacturer of the firearm before purchasing. Larger Window The Calf X1 features an extended 27mm wide window and is great for shotguns, rifles, or competition pistols where concealment is not a priority and faster target acquisition is desired. MDS MODE MDS Stands for Motion Deactivated Standby, Cyelee products will NEVER have an automatic shut-off, they can ONLY be shut off by manually holding the down/- button for 4 seconds. However while ON the optic is always checking if it needs to go into MDS Mode. If it senses no movement for 5-7 minutes it will enter MDS Mode, when it senses motion in MDS Mode it will display the red dot within a second. SPECS Objective Len: 27mm Illumination Settings: 8 for daytime and 2 for nighttime Windage & Elevation Adjustment Range: +/- 40 MOA Reticle: 3 MOA Red Dot Battery: 1 x CR1632 with up to 50,000 hours of battery life Operating temperature: -10°C to +60°C Waterproof: IPX7 Mount Type: Doctor Cut Ease of Shooting WINDOWSLESS WATERPROOF Tired of cleaning a filthy LED window when your optics red dot picture is obstructed and filled with brightly lit pieces of dirt? With Cyelee Optics Windowless Waterproof LED Emitter technology you will never have to clean your second LED emitter window again, and the optic remains fully IPX7 waterproof! When it's time to take a shot, you want the clearest unobstructed view possible, ditch the second tiny LED emitter window and go with Cyelee Optics Windowless Waterproof Technology for the crispest and most consistently clean sight picture. Daylight Bright When we say daylight bright we mean so bright you can't use the highest settings indoors. Utilizing a multi-coated lens for Red Dot versions to boost perceived brightness and battery life, our optics have multiple settings below what human eyes can perceive for enhanced low-light optic(NV) devices. But they are also bright enough for noon desert shooting, for use with high lumens flashlights, and for when the sun is bearing down on you, don't miss a beat. Shockproof Shockproof up to 1500Gs, what more is there to say? Our optics hold up to recoil, and it's not even close.

I actually do have this mounted on a shotgun, but it’s a Smith & Wesson M&P 12 which is a tactical shotgun that doesn’t come equipped with any sights. That being said, this red dot comes equipped with a picatinny mount and will mount on anything with picatinny rail. Happy hunting! **Q: Which Glock mos plate for a 45 mos?** A: Vortex Venom ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***R on September 6, 2024* ### ⭐⭐⭐⭐⭐ Review *by D***H on July 23, 2025* ### ⭐⭐⭐⭐ Review *by M***L on March 27, 2026* ## Frequently Bought Together - Cyelee Larger Lens Shake Awake Red Dot Sight for Pistol, Micro 3 MOA Reflex Sight for Doctor Cut(Calf X1) - DPP Titanium Rear Sight Dovetail Mount/Mounting Plate/Adapter Compatible with Glock Vortex Venom & Viper, Burris Fastfire, Docter - Loctite Threadlocker Blue 242 - Removable Thread Lock Glue for Nuts, Bolts, & Fasteners, Medium Strength Screw Glue to Prevent Loosening & Corrosion - 6 ml, 1 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/375557909-calf-x1-red-dot-doctor](https://www.desertcart.hr/products/375557909-calf-x1-red-dot-doctor) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-18*
