3/8インチ11mm→7/8インチ20mm ダブテール→ピカティニーアダプターマウント ロープロファイル 11mm→21mm ピカティニーライザーマウント (DV11-9S)

Installed this on my air rifle and the Picatinny rail lined up perfectly with my red dot. The fit on the 11mm dovetail is snug with no wobble, feels solid.

The low profile is perfect — this mount barely adds any height, so my red dot sits right where my old scope did. It locks onto the 11mm dovetail securely with no wobble, and the Picatinny section lined up exactly for a clean install.

Exactly what I needed to put a modern red dot on my vintage .22; the low profile keeps everything sleek. It clamped down tight on the dovetail with no wobble, and the Picatinny section feels solid.
