Manufacturer’s Notice
This ammunition is optimized for use in short-barreled .300 AAC Blackout platforms, generally
10.5″ barrels and under. Subsonic ammunition performance can vary depending on barrel
length, twist rate, suppressor design, and firearm configuration.

Suppressor Use Notice:

This ammunition is designed with suppressed use in mind; however, users should always confirm safe firearm setup before suppressor use. Before attaching a suppressor, verify projectile stabilization and safe operation by firing unsuppressed and inspecting targets for clean, round impacts. Confirm suppressor alignment and barrel concentricity prior to use. Do not continue firing if keyholing, unusual sound signatures, point-of-impact anomalies, or signs of projectile instability are observed. Always follow suppressor manufacturer guidance and ensure all components are properly installed and torqued.
