Description

Simple problems demand simple solutions. AT3's Pro-Mount risers do just that, offering two different heights for cowitness with backup sights, while remaining lightweight and appropriately rugged.

Simple problems demand simple solutions. AT3's Pro-Mount risers do just that, offering two different heights for cowitness with backup sights, while remaining lightweight and appropriately rugged. The Pro-Mount risers work with wide variety of micro red dots that attach to Weaver or 1913 Rails. Depending on your personal preference for sight height, you may opt for the 0.83" Riser, or the 1.0" Riser. If you like your sights all on the same plane, or don't plan to use backup sights, the 0.83" Riser is a good fit. It's what most folks tend to prefer. If you prefer a less obtrusive view with backup sights deployed, or find yourself hunching to get a good sight picture, the taller 1.0" Riser may be right for you.

  • Great coating. Perfect high quality mount
Style: .83 Inch - FDE
Very nice coating. Very durable, brings the sight to eye height quickly. Slightly smaller than expected but that's definitely a good thing.

  • This is a perfect budget riser.
Style: .83 Inch - FDE
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. ... show more

  • Doesnt co-witness whatsoever
Style: .83 Inch - FDE
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.

  • Smaller than expected / top notch construction grade
Style: .83 Inch - FDE
Very solid build, but I underestimated the size of the top picatinny area. Unless you have a small optic, or something to put on top, measure how many bars on the picatinny you will need in advance. I would have loved to keep it, very strong build, but I didn’t want my optic to hang off the edge. Not advisable for Eotech or Holosun optics ... show more
