Great lightweight option.

I used this barrel and the recommended low profile gas block with stainless gas tube on a custom side charger receiver. For a 13.7"-16" length barrel the mid length gas system is hard to beat. It behaves more like the original Stoner design with the 18" rifle length gas system thereby improving the recoil impulse and reliability of cycling. The barrel from Faxon is perfectly machined and fit as designed. Once I dimpled the barrel for the gas block everything stayed in place and has held up to numerous mag dumps. I plan on building this up to be a nice target rifle for my woman. Light weight and accuracy are the top 2 positives of this barrel. For this price I can't see a downside. Buy with confidence.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Light Weight AR Build

Building a light AR and purchased this Faxon pencil mid length barrel. It was packaged well and appears to be a quality item. At just over a pound its going to help get my carbine in the 4.5 to 5.5 lb range. The 3 star rating is based on its overall appearance, price and the service provided by AT3. I will bump the rating up or down when I get to put rounds down range. Thanks AT3 for excellent products and service.

Thanks for your feedback, EH. We're glad you're satisfied with your purchase - AB
