I have had most of them except the Armalon. I've ended up getting the newest generation of Addley mount. Made in Canada and the rail is long, almost up to the receiver ring...so you can mount big long modern scopes with it.
I like the way they mount up. And you can use a Mk II flip sight so you still have irons.
I changed the screw he included to replace the ejector screw out for a buttplate screw, which has the right pitch. (not one mount I've encountered has the right screw with it- apparently none of the mount makers have ever heard of BA screws) They all expect you to reef the wrong screw into your receiver, thus changing the threads...

Personally, I like a screw to go in with your fingers, then I know it's right.
S&K are good but too short IMHO. (and you lose the irons)
Cad Technik sit so high, you basically have a chin weld.

(but you keep the irons, and the mount is quick release with 2 thumb screws, leaving you with irons)
B Square are pretty good. Very lightly built though and made in China as I recall. I had to change out all of the fasteners they included. You can use a Mk II flip sight with it.
