The Griffin Armament Cantilever Mount is a rugged, precision-engineered optic mount designed for shooters who demand reliability, repeatable accuracy, and a proper cheek weld on their modern sporting rifles. Built from 6061-T6 aluminum, finished in black, and configured for 30mm scope tubes with an integrated 15 MOA incline, this model GSM1.335H30MM (UPC 791154083888) delivers rock-solid performance for AR-style rifles and other flat-top platforms.
If you’re looking for a 30mm cantilever scope mount with built-in 15 MOA for extra elevation at distance, the Griffin Armament Cantilever Mount is a smart, high-value choice for hunters, competitors, and precision shooters.
Purpose-Built 30mm Cantilever Scope Mount
This Griffin Armament Cantilever Mount is engineered around the needs of the modern AR shooter:
30mm ring size – Compatible with a huge range of popular LPVOs (low-power variable optics), mid-range scopes, and precision optics with 30mm main tubes.
Cantilever design – Pushes the optic forward over the handguard for proper eye relief, especially important on AR-15 and AR-10 platforms.
Optimized height – Designed to deliver a comfortable, heads-up shooting position and consistent cheek weld on flat-top receivers.
The result is a mount that positions your optic where it needs to be—without forcing you into awkward head positions or compromising on eye relief.
15 MOA Built-In Elevation for Extended Range
One of the standout features of this mount is its integrated 15 MOA of incline:
Adds 15 minutes of angle to your optic, giving you additional elevation adjustment for long-range shooting.
Helps keep your scope’s internal elevation turret closer to the optical center, which can improve tracking and image quality at distance.
Ideal for shooters who regularly stretch their rifles to mid and long-range and want extra “up” in their dialing capability.
Whether you’re shooting steel at 600 yards and beyond or dialing in for practical field distances, the built-in 15 MOA makes this mount a better long-range tool than a standard flat mount.
Strong, Lightweight 6061-T6 Aluminum Construction
The Griffin Armament Cantilever Mount is machined from 6061-T6 aluminum, a proven alloy known for its balance of strength, machinability, and low weight:
Durable yet lightweight – Adds minimal weight to your rifle while still delivering a robust, rigid platform for your scope.
Precision machining – Ensures proper ring alignment and secure clamping without distorting your optic tube when installed correctly.
Black finish – A tough, non-reflective coating that resists scratches and blends seamlessly with most modern black rifles.
This mount is built to withstand real-world use on the range, in competition, and in the field.
Solid, Repeatable Scope Retention
A quality optic is only as good as the mount holding it. The Griffin Armament Cantilever Mount is designed to:
Clamp securely to standard Picatinny top rails.
Provide firm, even pressure around 30mm scope tubes.
Maintain zero under recoil, so you don’t lose your point of impact after long days of shooting.
With careful installation and proper torque, this mount is built to deliver repeatable performance, even on hard-use rifles.
Ideal for AR-15, AR-10, and Other Flat-Top Rifles
The geometry and height of this cantilever mount make it particularly well-suited for:
AR-15 / 5.56 carbines and rifles
AR-10 / .308 & 6.5 Creedmoor platforms
Other flat-top Picatinny rail–equipped rifles needing forward-mounted optics and proper eye relief.
The cantilever pushes the scope forward to accommodate:
It’s a natural fit for serious AR builds that need a versatile optic setup.
Clean, Professional Aesthetic
In addition to being functional, the Griffin Cantilever Mount has a clean, professional look:
Black finish matches most receivers, handguards, and accessories.
Streamlined design avoids unnecessary bulk while still looking purposeful and modern.
Looks at home on both tactical-style rifles and refined precision builds.
If you’re building a rifle that needs to perform and look sharp, this mount checks both boxes.

Installation Notes and Best Practices
For best results when installing the Griffin Armament Cantilever Mount:
Ensure your rifle is unloaded and safe before beginning any work.
Place the mount on your Picatinny rail, generally bridging or just ahead of the upper’s receiver rail, then snug the base screws to align.
Set your scope in the rings, adjust for proper eye relief and reticle level.
Tighten ring caps incrementally in a cross pattern to recommended torque values (consult Griffin’s or your scope manufacturer’s torque guidance).
Confirm that there is no scope tube binding and that the optic maintains its zero after test firing.
Proper installation helps prevent point-of-impact shifts and ensures the mount provides reliable performance under recoil.
