Compact 9mm Platform Built for Control

The Eagle Eye kit delivers a short overall length while maintaining the ergonomics and modularity of the AR platform. The 8.3-inch barrel cycles reliably with 9mm ammunition and the medium profile keeps weight manageable. The nitride finish on both barrel and bolt carrier resists corrosion and simplifies maintenance compared to standard mil-spec finishes.

Glock Magazine Compatibility

This build uses a 9mm bolt carrier group with an external extractor designed to feed from Glock and Colt magazines. That means you can leverage existing Glock magazine inventory and enjoy the cost savings of widely available ammunition. The kit is configured specifically for this magazine ecosystem, so feeding reliability is built in from the start.

SBA3 Brace and Pistol Configuration

The SBA3 brace is adjustable and provides a stable shooting platform for accurate follow-up shots. The kit ships with the brace installed and ready to use as a pistol. This configuration keeps the build in pistol status under federal law, requiring no tax stamp or NFA registration.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. Verify all local and state regulations regarding pistol braces before assembly and use.
