Questions & Answers
Sirs, is the Faxon 10.5 barrel shipped with a low profile gas block and is it actually including a pinned compensator. Thank you for your input. Manufacturer Answer

This barrel ships with a pinned gas block, not a pinned compensator. Note, the barrel will ship with the gas block on the barrel, and the pin in a baggie within the barrel packaging, we don't pre-install it so you can get your barrel nut installed.
