This barrel is worth buying for a light and durable build - Faxon Firearms 5.56 NATO Gunner Rifle Barrel

I love Faxon barrels. This one does not disappoint. It weighs very little compared to the rest of my gun and that helps with overall balance when shooting. It's tricky to use my Superlative Arms gas block because the gas block is set up so in front that it butts up against my ASR muzzle device. I am not able to adjust the gas without removing the muzzle device every time. Other than that, the 11.5 inch barrel is perfect for my needs and it locks into my upper receiver snuggly without having to fight it like some other barrels I have owned.
