Zero-Retention Tested
// 01 — Zero Retention

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.

Live Fire
5,000 round endurance — .1 MOA
Lab Tested
.01 MOA
Standard
Mil-Std 810F Method 514.5
Return-to-Zero Tested
// 02 — Return to Zero

Return-to-Zero Tested

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

Live Fire
(50) cycles / 5,000 rds — < .20 MOA
Lab Tested
(50) cycles — .01 MOA
Standard

Drop Shock Tested
// 03 — Drop Shock

Drop Shock Tested

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.

Result
.21 MOA RTZ post-drop live fire
Drop Height
1m & 2m onto concrete
Standard
Mil-Std 810F Method 514.5
Shock & Vibration Tested
// 04 — Shock & Vibration

Shock & Vibration Tested
