Weaver Top Mount 90 Scope Mount – Black, Fits Marlin 39A
Weaver invented the cross-slot base pattern that the whole industry now calls a Weaver rail. Their mounting hardware has been the affordable, available answer on American hunting rifles for generations. One-piece mounts trade adjustability for rigidity. Everything is machined in a single block, so ring alignment is set at the factory rather than something you have to lap in.
It mounts directly to the receiver, so fitment is specific to the action it was machined for — check the fit before ordering. Aluminum construction keeps weight down without giving up the rigidity a mount needs.
This one is machined specifically for the Marlin 39A. Mounting hardware is action-specific, so confirm your exact model and generation before ordering — a base that is close but not correct will not sit square.
