2件 30mm 瞄準鏡環，中型輪廓鏡座，適用於 Picatinny/Weaver 軌道

The medium height was exactly what I needed for my bolt-action rifle, and the 6-bolt screw design really locks the scope down tight. Even after a box of heavy loads, nothing shifted—no need to re-zero. A solid, no-fuss mount for the money.

Bolted these onto my .308 and the six screws per ring held the tube dead solid through a full box of cartridges. The medium height sat my 50mm objective just barely above the rail, which is exactly what I needed.

The six-bolt design on each ring clamped down evenly and securely on my scope tube with no shifting at all. I mounted these on a heavy-recoiling rifle and they held zero perfectly through a full range session.
