excellent product

Pretty good quality just what I was looking for Works well

To be clear, you do receive TWO rails. They are quite solid and screw on fairly easily. That said, the reason for one deducted star; I'm pretty sure, you need a WIDE flat-head screwdriver to "lock" the screws tight! The included Allen wrench appears pointless. I even remember using a butter knife sideways to tighten the screws. Hand tightening these, is just not a smart idea. You'll NEVER get them tight enough to stay in place for sure.

Ii got 2 different piccatiny profile risers. 1 is 1” and the other was 1/2” riser both for $19.99. Good price. I wasn’t sure which one would fit me better but now I know. I have an extra, but that’s okay. It fit my scope and I’m happy with my purchase. Very easy to put in. It wasn’t heavy at all. Is very durable . Can’t complain

Be careful not too over tighten the screws they break easily. I also suggest blue lock tight they will loosen quickly if you don’t.

Positioned scope for easy sighting in.

I was sent 5 of these when I intended to buy 2. There are 2 cross bolts on each riser, intended to locate it and secure it to your rail. One of the bolts on each riser is intentionally milled to half diameter which reduces its strength by at least half. One of the cross bolts notches on each riser is mislocated and does not match the spacing of a typical rail. Thus, the reason for the milled bolts. Sure enough, when torquing the first riser to the rail, the bolt sheared before it was tight enough to secure the riser. Having learned from that breakage, I didn’t torque the second riser nearly enough to feel confident it won’t launch into outer space. I cannot recommend these risers while I’m returning them and wanting a complete refund.

Perfect.
