Zero-Retention Tested
GDI mounts retain zero during extensive live-fire usage and laboratory testing performed against shock and vibrational profiles that exceed military specifications.
Engineering excellence in research, development, testing, and functionality. Marksman Grade Engineered Mounts™ tested against and beyond MIL-STD-810 protocol standards.
We are veterans at our core and engineers by trade— committed to delivering excellence to our brothers and sisters serving the United States military, government, and law enforcement communities.
We are committed to engineering excellence and innovation in building critical lifeline product. This is our ethos in developing our Marksman Grade Engineered Mounts™.
GDI mounts are subject to extreme environmental testing to ensure maximum reliability and survival in the world's most demanding theaters of operation. Testing protocols current to active MIL-STD-810 revision standards.


GDI mounts retain zero during extensive live-fire usage and laboratory testing performed against shock and vibrational profiles that exceed military specifications.

GDI mounts return to zero following repeated removal–remount cycles during extensive live-fire usage while subjected to harsh mechanical stresses.

GDI mount attached to optic and host weapon with full magazine — no physical damage when repeatedly dropped (3x, sight down) onto concrete from 1m and 2m.

Exceeds MIL-STD-810 standards for 3-axis shock and vibrational profiles encountered during shoulder-fired, crew-servied, tripod / pintel mounted operator field handling, helo, HMMVEE vehicle transport (loose cargo).

GDI mounts are built to survive maritime operations and have successfully completed salt fog corrosion testing with no damage or degradation of performance after >96 hours of exposure per ASTM B117-90.
