From orders that included this itemProduct description
The PRO-MOUNT is our improved riser for the AT3 RD-50 Red Dot Sight and all other picatinny-mount red dot sights. Lightweight, low-profile, and canted for faster target acquisition.
The new PRO-MOUNT riser is packed with premium features in a sleek package, without the high-end price tag. The cantilever design places your optic further forward, which makes guiding your eye towards your target even faster. The skeletonized body of the sight keeps weight low without sacrificing the strength you need for staying on target in rough conditions. And to keep things snag-free, we’ve switched to a bolt and lock nut for a tight fit that won’t get caught on your gear.
There are 2 options available:
- 1″ Hi Profile Riser – Raises your optic by 1″, which is perfect for a lower 1/3 cowitness on most red dot sights
- .83″ Med Profile Riser – Raises your optic by .83″, which is perfect for an absolute cowitness on most red dot sights.
