Review: Good Quality, Holds Zero - Lightweight and rock solid. Comes with a torx wrench and a spare mounting bolt in case you strip one. It looks good on the rifle and doesn't move under recoil or from moderate bumps. Good quality finish holds up well. Excellent mount for Bushnell TRS 25 and Primary Arms mini red dots. With Magpul MBUS sights, the 0.83 inch riser gives you a nice lower 1/3 cowitness. The sights sit below the dot in the lower third of the glass when looking at the dot alone. The 1.0 inch riser will just barely cowitness, but you can only see the very top of the front sight blade when using the iron sights with MBUS and the aforementioned red dots. The 1.0 inch riser was too tall for me, couldn't see enough of the front sight post, and much of area around the post is blocked by the emitter with the TRS 25. I've not tried the 0.75 inch riser, but I suspect it offers an absolute cowitness with the TRS / PA / MBUS setups. Pro Tip: If your iron sights are zeroed in, you can easily zero in your red dot without firing a single shot. Just look through your iron sights in perfect alignment while adjusting the elevation and windage of the red dot so that the dot sits on the top center edge of the front sight post. Make sure you are looking through both front and rear sights in perfect alignment when you do this. This works regardless of the height of the mount or type of cowitnes, and some people think this is cowitnessing. It is not the same as an absolute cowitness, which might explain the conflicting info on riser heights and cowitness. All correctly zeroed iron sights and red dots will appear to be cowitnessed when looking through the iron sights, regardless of the height of the riser. However, with a lower 1/3 cowitness, the dot is also visible above the sights when you move your eye above the iron sights.
Review: Too Tall For Back Up Iron Sights - Good Quality and Design, But need to read more for an issue with being too tall if using iron sights for back up. …the product is well deserving the highest rating of five stars… it is manufactured in Taiwan and reflects the years of experience manufacturing quality tools for the trade industry (unlike cheaply engineered by PRC companies like Monstrum) this is the second one I purchased to be used as riser block for a RDS on my ARs. The first was the .5” height and it was installed on an AR carbine with a Vortex Defender ST with Magpul BUIS as backup sights. The set up is comfortable with the Magpul carbine stock and is “co-witnessed” with the iron sights. I now find I don’t crawl on my stick as much as when younger and wanted to try a hight mounted sight… so I ordered a taller one fir my other gun. My second one is the .83” height… to mounted on the same type gun and sights… when installed, found height very comfortable for my head position… BUT, the height took the iron sights out of play… the front sight was no longer visible… eliminating the back up function Was going to order the .75” version but decided to go with what already a known workable height (.5”) Maybe with a different RDS with a bigger window the higher base may work… not with the Vortex Defender ST

### ⭐⭐⭐⭐⭐ Excellent for the price - perfect height & light weight
*by V***D on October 17, 2025*

Works as advertised, was a breeze to install, and holds fast. I used blue loctite on it, so I'm not worried about it coming loose. Love the .83" height for co-witnessing. Overall, it's a great budget riser. I use mine with a Bushnell trophy micro-dot.
