Geissele Automatics 36Mm 1.54'' High 20 Moa Zero Compromise Scope Mount Black

The Geissele Automatics 36mm Zero Compromise scope mount is purpose-built for precision shooters running high-end optics on long-range systems. This 1.54" high mount pairs a 20 MOA built-in cant with an extended 2.5" cantilever design, giving you the reach to dial extreme distance and the eye relief you need without a bridge mount. If you're stretching shots far beyond typical hunting ranges or running precision competitions, this mount is engineered to keep your scope locked down hard and return to zero every single time.

Geissele machines the mount from solid billet 7075-T6 aluminum with line-bored rings sized specifically for 36mm scope tubes—no lapping required. The nut-and-bolt clamping system applies 1,400 pounds of force, tripling the hold of lever-based systems. You'll install it with basic hand tools and no torque wrench, yet it delivers the rock-solid repeatability that separates good mounts from great ones. The reinforced six-screw ring design and individually serialized caps ensure perfect alignment and absolute retention of your optic.

Built in Type 3 hard coat anodize, this mount handles abuse without compromise. Whether you're running it on a precision long-range rig, a competition build, or a hard-use tactical platform, it's designed to perform under conditions where failure isn't an option. This is what happens when a manufacturer stops cutting corners and builds a mount that actually lives up to its name.

Frequently Asked Questions

What 36mm scopes is this mount designed for?

The mount was purpose-built for Geissele's Zero Compromise ZC420 optics series, though the line-bored 36mm rings accommodate any 36mm scope tube. Geissele machines the rings to fit 36mm bodies without requiring lapping.

What's the 20 MOA cant for?

The built-in 20 MOA (5.7 MIL) cant tilts the optic forward, extending your usable elevation adjustment range. This lets you dial further distance without maxing out the scope's internal elevation travel, which is critical for extreme long-range precision shooting and competition applications.

Do I need special tools to install this mount?

No. The nut-and-bolt clamping system installs with simple hand tools commonly found in any gunsmith kit or garage. Unlike lever mounts, there's no torque spec to fiddle with, making installation and removal straightforward.

How does the 2.5" cantilever affect eye relief?

The extended cantilever moves the optic further forward on the receiver, giving you proper eye relief without needing a bridge mount. This is especially useful on short actions or when running longer-magnification scopes that require more distance from your eye.
