Optic Mounts You Can Rely On

Our assessment of the key failure point factors has brought us to the end-state conclusions that have forged our ethos in building an uncompromising system of mount interface devices.

Our committed understanding the critical mechanical and functional dynamics of how mounts fail, allows us to deliver a reliable ruggedized optic mount solution. Our mounts deliver.... EVERY SHOT, EVERY TIME.

Precision Engineered

Pursuit of Excellence

The foundation of superior performance begins with the relentless pursuit of engineering excellence.

Form, Fit, and Functionality take precedence......NOTHING LESS WILL DO.

Our engineering processes drive each product through the crucible of exhaustive research, development, testing and evaluation, to determine the merit of a design, and most importantly, its reliability and performance under the most arduous mechanical and environmental testing.

We evaluate critical performance parameters—downrange and in the lab, so those who put their lives on the line get the most reliable product available. WE GOT THEIR SIX.

We are about the RED, WHITE & BLUE.....UNITED in our Way of Life. Putting out Downrange when called on, Respecting our Elders, Protecting our Women & Children, Honoring our Veterans, and Building the most Reliable Optic Mounts on the planet.

We deliver an uncompromising commitment to build a superior mounting system and supporting the mission of saving the lives of those who go into harm's way.

Precision Engineered Mounts

Reliability - Every Shot....Every Time

GDI optic Mounts are precisely engineered and tested with combat proven functionality to maximize your marksmanship. We understand that Every Shot Counts, Every Time.

Performance

GDI’s precision engineered sight mounts are designed for rugged field use and reliable accuracy enhancing application on MIL-STD M1913 Picatinny / NATO STANAG 4694 accessory rails.

Our mounts have undergone extensively rigorous live fire, drop test, and environmental testing and evaluation that exceeds the performance capabilities of commercially available sight mounts.

Reliable Accuracy Matters: GDI mounts have exceeded stringent DOD testing requirements for performance by exceeding Mil-Std 810F Method 514.5

GDI mounts were originally built for military/LE use and are combat proven in the harshest of unforgiving environments. Our industry partners and end-user customers depend on our expertise. Whether for your profession or passion, you can rely on GDI’s superior design to get the job done right the first time.

Zero Retention

Standard scope mount designs come loose during live fire usage, during transport, and as a result of accidental dropping. Loosening of the optic mount on Picatinny / NATO rail due to the subjected shock and vibrational forces causes a loss-of-zero and loss-of-accuracy. The net result leaves the marksman with an unsecured and out-of-zero scope that compromises accuracy and survivability.

Return to Zero

Removal and remounting of standard scope mounts from weapon platforms (for cleaning, maintenance, or mission specific configuration change-over) utilizing various optic / imaging devices, causes a loss of the scope's zero (>1.0 MOA). Consequently, soldiers are potentially returning back to combat operations w/out-of-zero weapons. Logistics constraints in theater due to range availability, location, operational commitments, etc., make it unfeasible / impractical to re-BZO (zero) the weapon as needed.

Adjustable to Worn / Out-of-Spec Picatinny Rails

Rails vary in dimensions from manufacturer to manufacturer. In some instances, .010” - .020” oversized (or undersized). Our mounts are adjustable to these deviations in tolerances. Once adjusted, no tools are required for mount removal/remounting. No special tools required for initial mounting—adjustable w/ flathead screwdriver.

Benefits of Our Products

Non-Abrading / Non-Gouging Quick Detach (QD) lockdown mechanism

GDI ALQD™ (Auto-Locking Quick Detach) lever system prevents wear and damage to the M1913 Picatinny / NATO rails, whereas cam type QD lever mounts rely on friction, resulting in degradation of the rail’s dimensional integrity.
