I cannot recommend specific scopes or mounts for the AK-47, as that would depend on your intended use. However, here are a few general tips on selecting AK-47 Scope Mounts:
- Make sure to get a mount designed specifically for the AK-47, as the mounting requirements are different from other rifles due to the AK'sunique receiver and dust cover design.
- Opt for a sturdy, high quality mount from a reputable manufacturer. Some good options are RS Regulate, Midwest Industries, and Ultimak. Avoid cheap mounts as they can lose zero or fail under recoil.
- Consider whether you want a side mount that attaches to the AK's scope rail or a top mount that replaces the dust cover. Side mounts tend to hold zero better while top mounts allow for lower 1/3 co-witness with iron sights.
- For magnified optics, make sure the mount raises the scope high enough for comfortable viewing and provides enough eye relief. Higher mounts usually allow for better cheek weld too.
- Make sure the mount properly fits your AK variant - AKM, AK-74 or Yugo patterns, etc.
- Follow all instructions carefully for installing the mount and maintaining proper torque specs on screws. Use thread locker.
- Confirm the mount is on securely and does not shift or wobble when installed. Test for adequate clearance and eye relief when mounting your scope.
Those are some tips to help choose a solid AK-47 scope mount. Always use caution and proper safety practices when installing optics and accessories. Let me know if you have any other questions!
