34mm/1.34 inch 4 Slot Scope Adapter Ring Mount Weaver/Picatinny Rails

Our Take

An adapter that puts a 34 mm scope ring on a Weaver or Picatinny rail — 45 x 20 mm, 46 g, metal. The 34 mm tube size is the whole compatibility question: it’s the big-tube class common on long-range scopes, and it will not accept 30 mm or 1-inch tubes, so don’t buy it hoping to adapt down. The ‘fits Weaver/Picatinny’ claim usually holds because the clamp sits in the middle ground, but confirm with your rail. If your tube is 34 mm, this is a simple, cheap solution to a mount problem that otherwise costs real money.
