The InfiTac PA03 Glock MOS Pistol Adapter for FMP13 & FML19 is a precision-engineered mounting solution that allows InfiTac FMP13 and FML19 red dot sights to be securely installed on Glock MOS (Modular Optic System) pistols. This adapter bridges the gap between Glock’s factory MOS cut and InfiTac’s optic footprint, providing a stable, low-profile, and reliable mounting platform for shooters who want to run InfiTac optics on their Glock handguns.
Why Choose the InfiTac PA03 Glock MOS Adapter?
Many Glock owners choose the MOS system for its versatility, but not all red dot sights are directly compatible with the Glock MOS footprint. The InfiTac PA03 adapter solves this compatibility issue by providing a dedicated interface between the Glock MOS slide and InfiTac’s FMP13 and FML19 red dot sights. Precision machined from high-quality aluminum and finished with a durable hard coat anodizing, this adapter ensures a secure fit while maintaining a low mounting height for optimal co-witnessing with iron sights. Whether you’re building a competition pistol, a home defense handgun, or a duty-ready Glock, the InfiTac PA03 delivers the stability and reliability needed for consistent optic performance.

Performance and Build Quality
The InfiTac PA03 Glock MOS Pistol Adapter is manufactured to exacting tolerances to ensure a precise and repeatable fit on Glock MOS pistols.
