These mounts are suitable for some applications, and unsuitable for others. A dab of green or blue Loctite will resolve any concern regarding the windage screws loosening, provided you first degrease the screws. An advantage this style of mount has is that small windage adjustments can be made, using the windage screws, allowing the windage turret to keep it's mechanical center. Once the correct windage is acquired, the port side screw never needs to be touched again, and can be made permanent with epoxy or red Loctite.
A disadvantage of this mount is the temptation to treat it as a QD, and twist off the front dovetail ring using the scope as a handle, risking damage to the scope tube. Some of these dovetails are pretty tight, so the ring should be installed and removed with a thin wrench. If you are going to use that rifle for different applications, requiring several different scopes, repeatable QD rings are a better choice; but for use with a single scope, the mount is very strong and reliable. You can spend a great deal of money on scope mounts, without getting a stronger mount.
