In my opinion, a great price for a beautifully machined piece of aluminum. Fit on a Weaver Rail is very tight, need to tap on with a brass hammer. However, if you want something that won't move under recoil and don't care about having a quick detach, this is the mount. I am buying 2 more risers and stacking them (since they are so solid) to put on a .556 to replace a 1" quick detach riser I have on it now.
Pros: Rock Solid Mount, fits like a glove on a Weaver Rail
Cons: Minor - Need to be able to "slide" the mount on your rail
