Radian Weapons Guardian + SIX BUS | Glock MOS | H0016

The Radian GUARDIAN + SIX BUS optic mounting system secures and protects pistol red dot optics on Glock MOS slides while offering integrated iron sight redundancy. Machined from 7075 aluminum and finished with a hard anodize, the design provides top, front, and side impact protection and a low-profile sight picture. The system employs the STUD-LOK threaded stud/nut mounting interface for increased thread engagement and shear resistance, and TRU-SEAL with pre-installed O-rings to maintain a watertight seal at the mounting plate.

Its design is suitable for everyday carry (EDC) and competition shooting where a robust optic mounting solution and a reliable backup sight option are required.
