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

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

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.

I put this on a PCC with a Holosun 510. It's not 'skyscraper' high touted by some 'operators' but definitely helps with a more heads-up stance appropriate for a short range defensive rifle. Had to adjust the quick release clamp on the Holosun as the Picatinny dimensions are narrower than the rail on my receiver but it definitely works. I got the FDE version and it's in the family of FDE although lighter shade than some components sold. For the price, it's very good. I'm not running iron sights so IDK if the tunnel on this mount interferes but I suspect it would not.

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.

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!

Installed this on a rifle and added a red dot. Works great.

The version I got was too short to make a riser for my Eotech but it was so nice I didn't want to send it back. I winded up using it on an offset mount to raise a pistol optic set adjacent to a LPVO.Even though I knew this would mean having to re-zero the optic, I didn't care. This provided better head position and was simply a better mount than the one I had. Essentially I spent money in ammo to keep it. That means I liked it.

Overall seems solid enough. Took off two stars for fitment and quality control issues.The mounting screw came prestripped, making it difficult to tighten and get a snug fit on the rail.Also, 1" is too high for a Holosun HS510C to be able to 1/3 co-witness fixed Daniel Defense iron sights. Disappointed since this height was recommended by the manufacturer for this purpose. Guess I'll hang onto this one and just order a .83" to try out for this purpose. Your miles may vary on this.
