This Faxon 10.5 inch Pencil Barrel is the lightest and most accurate pencil barrel available for sale in a short barrrel package.

RTB has teamed up with Faxon Firearms to deliver this premium barrel at a very competitive price point and with free shipping!

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.

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.

5 of 5 I like your products and attitude. March 4, 2019
Reviewer: out4trout from West Jordan, UT United States  
The barrel is fantastic.  Very very accurate for a 10.5 incher.  Additionally it is light.  I used this on an AR pistol build and it fills the bill exactly. RTBA is a great place to order from.  Fast accurate shipping at a reasonable price.

5 of 5 Just what I was waiting for May 27, 2017
Reviewer: Rob K  
Been waiting (and writing for) Faxon to come out with a 10-11"  pencil profile barrel. I've used a handful of their 16" pencil offering and have been extremely pleased with how well they function, and, how much heat drift they have.

Got the new build out to the range for 2nd time today. Very pleased with its functionality and quite pleased with how little heat shit it experiences when running hot. All my range friends that were out today liked it and were very surprised at how little it weighs in the full build-out.

Using a MI lightweight, AIM low-mass BCG, and a SLR Sentry 6 so I could tweak the gas to run well with that low mass carrier.  

I'll definitely be picking up a few of this barrel in the new future to update my wife and eldest's pistol upper builds.
