This Faxon Firearms 5.56 AR-15 barrel features an integrally machined 3-port muzzle brake, so you don’t have to send your barrel and muzzle brake off to a gunsmith, spend extra money, and wait a crazy amount of time to get your barrel pinned and welded to meet the overall 16” length. This gives you the lighter weight and better maneuverability of a shorter barrel without having to go through the NFA. The muzzle brake also features a slim outer diameter, so you can easily install and remove gas blocks. It features a mid-length gas system and gunner profile that reduces weight towards the muzzle while being more rigid near the chamber.

Faxon is always good

Great light weight and accurate way to have the shortest legal (without paperwork) barrel. Faxon makes great stuff and PA is the best place to buy ar-15 parts.
