Owners of the Faxon Sport in .300 AAC Blackout tend to appreciate the compact package the 10.5-inch configuration delivers, especially for use with suppressed subsonic loads. The Faxon barrel is a common upgrade target on other AR builds, so receiving it as the stock barrel on this pistol is a recurring positive in owner feedback.

The KAK Shockwave brace works well enough for most, though shooters with larger hands sometimes swap it out early. The M-Lok handguard gives enough real estate for accessories without adding unnecessary bulk to the overall package.

Value perception on the Sport is generally positive relative to comparable AR-pattern pistols in .300 AAC Blackout. The main criticism is that some buyers expect a complete, range-ready setup and are surprised to find magazine selection and optic mounting left entirely to them.
