AT3 Tactical PRO-Mount Mini Riser Mount - .83" and 1" - for RD-50 Red Dot Sight & Any Picatinny/Weaver Scope (1.0 Inch)

Tight fit super sturdy mount

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.

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

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.

I haven't put this riser to significant use yet, but so far, from mounting it alone, it feels really solid. It grips onto the rails nicely. It feels a little bit heavy though, and it uses a bit of a strange screw for mounting, which are my only two complaints so far. Other than that, it's a fine riser.
