BURRIS - Picatinny Riser Mount 1/2 Matte

I bought 2 of these mounts to install a Red Dot scope on my AR build. You will have to take the screws out completely and move the charging handle back out of the way and slide them on the rail from the rear. These are not traditional 2-piece mounts, they are solid 1-piece construction. I initially snugged them down carefully with the included T-15 Star ended Allen wrench. They would not tighten without some wobble left in them, hence my call to Burris. The Rep. told me that the recommended torque is 45/in.Lbs. but that is generally not enough to snug them down. He told me in their testing that generally over 100/in.Lbs. of torque was needed to tighten sufficiently. He recommended NOT using the included Allen wrench and use a T-15 Star bit screwdriver. I completed the installation and they tightened down quite well. Solid as a rock now. No stripping of the screws. He also told me that if they broke they would replace them no questions asked. The sight height is now perfect for Co-Witnessing through my Red Dot with my Magpul rear flip up sight to the standard A2 front sight.

Poor mounting design. Cross bolts should be beefy hex head. Impossible to get tight without stripping bolt heads. However was able to use bench vise to squeeze mounts so that the cross bolts could tighten the mount for a tight fit. Be careful not to squeeze the mount too much and have to pry the mount open to fit on rail. Good concept but poor design.

The mount is not true Picatinny, the footprint is larger and it will not tighten on the receiver rail. I torqued to the screws to the recommended 20 foot pounds and it is loose and moves forward and backwards. The screws cannot be tightened further without stripping, so this riser is essentially useless trash. as soon as I opened the packaging and saw the “Made in China” sticker on the bottom I knew this wasn’t going to be a good accessory. Disappointed because Burris claims to be a Colorado company. At least I now know not to buy anything else from them in the future.

It does fit to a Picatinny rail dovetail but the clamping screws do not fit the spacing groves on a Picatinny rail. Therefore I could not recommend this product for a Picatinny rail mount project. Also problematic is that this product does not have separate side clamping piece to attach to the rail. This could make your mounting project much more difficult.

without a movable clamp to the pic rail, the entire riser must clamp itself to the rail. however, it is an alum casting without any ability to "spring" at all and it is at least .050" oversize to begin with. After tightening the hardware you can grab the riser with your fingers and rattle it back and forth. (side to side)
