AT3 Tactical PRO-Mount Red Dot Riser Mount - .83 or 1 Inch Height - for RD-50 Red Dot Sight & Picatinny Reflex Sights

1. Height Choices for Optimal Alignment • .83-Inch Riser: This lower profile is perfect if you want to maintain a compact look and a closer cheek weld. With this height, the optic sits closer to the bore, potentially enhancing precision, especially if you’re shooting at close to mid-range. This setup is often preferred by those who want a low-mounted optic for better control and a more natural shooting position. • 1-Inch Riser: Elevates the sightline a bit, which can facilitate quicker target acquisition, as you won’t need to lower your head as much to align with the optic. If you plan to co-witness with iron sights, the 1-inch height typically allows for absolute or lower 1/3 co-witness, depending on your setup. 2. Compatibility with Your Optic and Blackout Recoil • Zero Retention: The PRO-Mount is crafted from durable aluminum, which means it can handle the recoil of a Blackout caliber. This is especially important on shorter barrels like yours, where the recoil impulse can be more concentrated. The mount’s design minimizes movement and loosening, so your optic maintains zero. • Secure Fit for Various Optics: Though it’s designed with the RD-50 in mind, the mount is generally compatible with other red dots that use a similar footprint, so you should get a solid fit for your chosen optic. 3. Quick and Easy Setup • The AT3 PRO-Mount is designed for easy installation, so if you’re looking to set up quickly or swap between mounts, it’s convenient. It requires minimal tools and time, making it user-friendly even for less experienced users. 4. Additional Considerations for Your 8” Blackout • Weight Distribution: With a short barrel, maintaining a balanced weight is essential to prevent front-heaviness. The PRO-Mount is lightweight, so it won’t shift the balance of your compact Blackout setup. • Sighting & Parallax-Free Advantage: The AT3 PRO-Mount with an optic is an advantage on a Blackout when you’re aiming for rapid, close-range targeting. The sight picture should stay clear and easy to acquire quickly, especially beneficial if your Blackout setup is geared toward quick engagement distances. This mount could be a great choice to complement your optic, offering versatility and durability tailored to a powerful, compact setup like your 8” Blackout.

Very nice coating. Very durable, brings the sight to eye height quickly. Slightly smaller than expected but that's definitely a good thing.

Tight fit super sturdy mount

I recently purchased the AT3 Tactical PRO-Mount Red Dot Riser Mount in the .83-inch height for my AR-15, and I couldn’t be more pleased with its performance. This lightweight cantilever mount is a fantastic addition to my setup, offering a perfect absolute co-witness with my iron sights. The skeletonized design keeps the weight down to just 1.1 ounces, which is ideal for maintaining balance on my rifle without sacrificing durability. The machining quality is top-notch, with a sleek black anodized finish that looks great and holds up well against wear. Installation was a breeze, thanks to the included Allen wrench and the single Picatinny rail slot that ensures a secure, snug fit. The cantilever design pushes the optic forward slightly, making target acquisition faster and more intuitive, which I’ve found especially helpful during dynamic shooting scenarios. What really stands out is the value for the price. The PRO-Mount delivers premium features—like recoil resistance and a low-profile, snag-free bolt and lock nut system—without the high-end cost. It’s compatible with my AT3 RD-50 red dot sight and other Picatinny-mounted optics, adding to its versatility. After several range sessions and over 300 rounds, it’s held zero perfectly, even under rapid fire. AT3’s lifetime warranty and excellent customer service give me confidence in this product’s longevity. For anyone looking to elevate their red dot sight for a clean co-witness and improved ergonomics, I highly recommend the AT3 Tactical PRO-Mount .83-inch riser. It’s a reliable, well-designed mount that punches well above its price point.

Mounted on a AR15 platform. This mount raises the red dot optic so as the optic aligns with my left eye, while shouldering form my right side. (I have a problem with my right eye) So far , after 100 rounds, the mount remains firmly attached to the picatinny rail and optic. Added bonus - looks very cool and comes with a very reasonable price.

Purchased once before wanted another one to match the same on all my AR's.I just wish they would make OD green color.

Using Holosun HS512c, this .83 mount is so far above the MBUS, is a ZERO cowitness. You cant see the irons at all. That was the only reason I purchased this thing.

Needed a high rise weapon mount for picatinny rail. Picked this beauty up for a good price. Materials are quality and it is light, 1” variant. Already slapped it on my rifle and mounted a reflex sight onto the top. Very happy with purchase!
