Burris Optics 1/2 Inch Picatinny Riser

Does what it should, could be a tighter tolerance mechanically between rails to help keep the riser from sliding if screw loosen.

Exactly what I was looking for to raise my magnifer to match my red dot sight. These guys and gals are the best in customer service and shipping speed.

Good mount. Excellent value.

Great little part for a low price

I have bought Burris products before, had both good and bad experiences with them But you can't beat primary arms when it comes to good service. It's hard to review a small item like this, it works fine. I'm just glad Primary Arms is around when you need to buy something. I have never had a bad experience with PA.

I needed a 1/2" riser for my trs-25 red dot and this does the job. Seems like a little too wide at the base, but that's probably me just being overly picky.

I needed a mount that was effectively priced, this one fits well and solid once in place.

I ordered a Burris riser for my AR. The description: Burris Matte Finish 1/2 inch Picatinny Riser Tactical Mount provides 1/2-Inch elevation for mounting rifle scope rails. Most gun scope installations require two of these Picatinny rail risers. This Burris Scope Mount can be used in conjunction with the Primary Arms Micro Green Dot Reflex Sight on an AR15..... The mount will not tighten enough to securely stay in place on a Picatinny rail. Thinking that I might have the wrong one I tried it on a weaver mount...the bolts and slots will not line up on that mount. I contact primary arms and was talking with a very polite gentleman about the issue. During the conversation he stated that he was experiencing some phone issues and if we were disconnected he would call me back. He confirmed the contact info. After a few moments we were indeed cut off, I have yet to received a return call.

I would like to thank you for the consistent excellent service and quick delivery. I highly recommend Primary Arms.

So I opened the package and slipped the riser onto my rail. The dimensions were so off it rattled back and forth. I couldn't tighten the supplied 2 cross bolts down enough to keep it from moving and wobbling on the top rail of my AR. I tried to shim it but that didn't work so I put it in a bench vise and cranked down on it. Of course I over tightened it.I finally got it on (had to hammer it in place with a soft mallet. If I had to do it again I wouldn't. I would have paid more and got a better product with a better fit.

The fit and finish is very nice. I bought this for an optic riser, without knowing the exact height I needed. It turned out to be higher than I was looking for. But I am not upset to have it sitting in my parts bin for possible future use, especially at it's meager price.

This mount slides on over the rail and is clamped down with 45 inch lbs. of torque to keep it solid. No knobs to get in the way. Smooth and compact design. Solid. Highly recommend this as a semi-permanent mount.

Good mount. Excellent value.

Just as several others stated, it does not tighten up to the rail. Fully tightened it is still loose. Obviously this makes it worthless for sights of any kind.

As others have stated, you can't tighten this down enough to keep it from sliding around. Total garbage.

This product has a single major design flaw: it lacks a free floating half of its lower rail mounting section, which prevents it from clamping down tightly. Subsequently, this riser slides freely back and forth within the slots of your rail. <br>Unfortunately, getting it to "flex" to the point where it pinches your rail securely, by tightening the mounting screws alone, is nigh impossible, since the whole item is a single piece of aluminum, and the recommended screw tightness is 20 inch pounds. Of course, you can do what another bold reviewer did and squeeze it in a vise. Just be precise or you may be facing a whole new host of issues (read his review).<br><br>This would have been a great product, as it's affordable, solid, and aesthetically clean, but due to this single egregious design flaw, my review goes from 5 stars to 1.<br>It's a cryin' shame...

Extremely poor quality. Attempted mounting this on several picatinny rails from manufacturers such as Geissele, ALG, Midwest Industries, BCM, Del-Ton, Spikes Tactical, and Anderson all torqued to the proper specifications as shown on the package with the same result. The female picatinny portion is out of tolerance and the riser rattles loose on the rail. Tried tightening the screws down as far as I could, still no dice. Spend the extra money and get a quality riser or mount.

I bought two of these to mount trs-25s on an AR15 and a Kriss Vector (based on the previous reviews). First neither of them would tighten down on the rail no matter how hard I torqued them. Secondly it does not raise the trs-25 high enough for a 2nd Gen Vector to cowitness the Magpul MBUS sights through. I could deal with the lack of cowitness but the base simply would not tighten on the rail.

I didn't read the reviews before buying. I had the same problem as all of the most recent. It wouldn't tighten on the rail. The screws are small and the frame isn't flexible, being one piece. I had to take a hacksaw and cut the top slit higher to give it enough flex so it would clamp down.
<br>If you read almost all of the reviews for the past couple years, here and other places, it's the same problem. It's a real shame that Burris isn't listening.
