16" Light Tapered, 40 S&W, 4150, NitrideFaxon
Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle-to-grave, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.
Quality is imbued into our barrels from the start. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.

*Note - Faxon Firearms advertises its barrels by their legal length. Pistol Caliber Carbine barrels have the chamber built into the barrel "extension" area, which makes them about ~1" shorter than centerfire rifle barrels.
I had been looking to build a 40 S&W upper. Did some searching and found this on sale. Great deal, nice fit and finish. Will definitely come back to Faxon for future builds.
Bought this to try a PCC build for indoor range use and new or young shooters. Barrel has been fired to fifty (50) yards with 1 1/2 inch groups off hand about as good as i'm able to shoot anyway. Cleanup was fast and easy. Only negative for my build was lower chamber rim needed a little breaking of the edge to prevent three point jam, not much just gentle noticible chafering. Would buy again and may as another shooter has asked for assistance in building him one.
