Add 50 MOA of Elevation Without Changing Your Base

When your riflescope runs out of elevation at extreme range, the Nightforce Wedge Prism 50 MOA picks up where your turrets leave off. This precision-built prism mounts forward of your scope and optically shifts the incoming image by exactly 50 MOA, directly adding to your available elevation travel. It's field-tested gear for shooters who need more vertical adjustment than their scope provides — no base change, no compromise. Whether you're reaching across a canyon on a backcountry hunt or dialing to extended range on a steel course, this rugged optic accessory delivers the extra travel you need.

Recover Elevation Your Turrets Can't Reach

When you dial to the bottom of your elevation turret on a 1,200-yard shot across a basin and still need more, that's not a training problem — it's a travel problem. The Nightforce Wedge Prism 50 MOA optically shifts your image by a precise 50 MOA, adding that travel back into your usable range without swapping bases or adding error-prone shims. At Hunt Premium, we evaluate every accessory the same way we evaluate glass: if it doesn't hold up when the shot matters, it doesn't earn a spot in our catalog. This prism is field-tested by shooters who push past standard range and need their gear to match the distance.

Optical Shift Without Mechanical Compromise

Optical Shift Without Mechanical Compromise

Unlike a 50 MOA tapered base that changes your mounting geometry and can introduce stress on the scope tube, the Wedge Prism works purely through optical refraction. It installs forward of your riflescope and shifts the incoming image by exactly 50 MOA without altering your mount, rings, or scope position. That means your zero retention stays exactly where it should — season after season, pack-in after pack-in. For a shooter who has already invested in a rugged mounting system and a riflescope that holds zero through hard use, this is the cleaner path to extended range.

Purpose-Built for Extreme Range Shooting

Purpose-Built for Extreme Range Shooting

The Wedge Prism 50 MOA is designed for one specific scenario: when your riflescope's internal elevation travel is exhausted and you still need to get on target. Available in 50 MOA and 100 MOA variants, this 50 MOA version is the right call for shooters who need moderate additional travel without the image degradation that comes with heavier optical correction. It pairs directly with Nightforce riflescopes but works with any optic where elevation limitation is the bottleneck — not windage, not parallax, not magnification. If your shots are reaching past 1,000 yards and your turret is bottomed out, this is the piece that closes the gap.

Compatibility Check

Confirm your setup before ordering — this prism requires specific mounting conditions to function correctly.

  • Your riflescope lacks sufficient elevation travel for your intended shooting distance
  • Available mounting space exists forward of your riflescope on your rail
  • Your riflescope is mounted on a compatible rail system

When You Need It

The Wedge Prism is not a general-purpose accessory. It solves one specific problem: your scope doesn't have enough elevation for the distance you're shooting.

When shooting at extreme ranges, many shooters find their riflescope lacks the necessary elevation travel. The Nightforce Wedge Prism is offered in 2 variants, 50 MOA or 100 MOA, that install forward of the riflescope to increase the effective elevation travel. The Wedge Prism optically shifts the incoming image to the riflescope by a precise elevation value, which directly adds to the available elevation travel within the riflescope.
