The American Defense 34mm 40 MOA scope mount is a quick-release lever-lock system built for shooters who need a rifle scope mount that stays put under recoil but comes off fast when you need it. If you're running an AR-platform rifle or any gun with a Picatinny or Weaver-style rail, this one-piece base with dual-lever design gives you the mounting security of a permanent installation with the convenience of tool-free removal and reattachment—ideal for hunters swapping optics between rifles or range shooters who prefer to store their scopes separately.
The core of the system is the lever-lock mechanism: depress the release tab and the lever swings open, letting the mount lift cleanly off your rail. The tighter you pull the lever, the more secure the clamp becomes, so recoil only locks it down harder. The locking bar on the side engages maximum rail real estate, while a crossbolt and two integral locking lugs prevent any creep across your rail under heavy firing. Whether you're left- or right-handed, you can orient the lever to lock toward the front or rear of your rifle to suit your preference.
Construction here is serious: five heavy-duty steel hex-head screws (three top, two bottom) clamp the vertically split ring halves together and hold your scope in an iron grip. The 34mm tube diameter fits standard rifle optics, and the 40 MOA base gives you elevation adjustment headroom for long-range hunting or precision shooting. Weight-saving cutouts in the ring and base trim pounds without compromising stiffness. An included flat-head screwdriver or even a coin lets you fine-tune the fit on oversized or undersized commercial rails for a no-slip hold.
This is the kind of mount that works just as well on a 6.5 Creedmoor hunting rig as it does on a 300 Win Mag or a 5.56 tactical build. If you demand reliable, repeatable scope mounting that doesn't quit when the gun goes boom, American Defense delivers.

The American Defense 34mm 40 MOA mount works on any rifle with a Picatinny or Weaver-style rail, including AR-platform rifles and other flattop guns. It accommodates oversized and undersized commercial rails thanks to the adjustable lever-lock fit.
Yes. The lever can be configured to lock toward the front or rear of your rifle, so you can position it whichever way suits your dominant hand and shooting style.
Depress the release tab on the lever and it swings open, allowing the entire mount to lift off the rail. To remount, align the base on the rail and close the lever—no tools required. The more you tighten the lever, the more secure the clamp becomes.
The 40 MOA base provides 40 minutes of angle of elevation adjustment built into the mount itself, giving you extra headroom for maximum-distance shots beyond what your scope's internal turrets can deliver. This is useful for long-range hunting and precision target shooting where you need to dial out elevation drops at distance.
