1/2" Picatinny Riser

This item serves it's purpose. I needed a 1/2" rise on a canted Optic. My issue with this item is that it is manufactured in such a way that there is a lot of clearance in the fitment. When mounted to my rifle it was loose. I needed to use a vise to bend the bottom to fit. I see no reason that this can't be addressed by the manufacturer. If for any reason I needed to remove this in the field I could not replace it as I don't keep a vise with me in the field.

In summary, it does serve it's purpose once I fixed it with a table vise. If this is intended in the design, it needs to be mentioned in the product description. Otherwise, it appears that Buris cannot manufacture a simple item to reasonible tolerances.

It slides into the main rail fine. The two bolts/screws that hold it in place are narrower than the grooves, so the riser moves. That definitely moves your scope when firing. So far, I can't find a riser that is snug.

This is very high quality, slides on to the rail and holds solid once tightened down. You may want to ditch the supplied Allen key and use a sturdy T handle key for the proper torque required to squarely secure the base in place.
