Awesome Lightweight Barrel


This barrel is the must use barrel for a lightweight AR Build! It looks good and is still quite accurate once warmed up. No wonder it is never in stock!

Awesome Barrel!!!!


I was amazed at the weight when I pulled it from the packaging. The only complaint I have was my own fault. It requires a .625" gasblock, I ordered a .75". So if you are replacing your standard barrel, go ahead and find a new gas block. I'm still breaking the barrel in. I've put about 200 rounds through it. Accuracy is good, even at hotter temps. No complaints at all so far. Faxon won my over with this one!

Light and accurate


Looking for a light weight barrel for an upper build for a female friend with some shoulder problems. Man this thing is light and I will say after about 200 rounds this has proven me that not only is it light, but it every bit as accurate as she needs. Glad I bought 2 barrels because I am working on my upper as I write this. Faxon has found the right combo in this setup.

Light weight


I couldn't Believe how light this barrel was When I received the box I didn't think it was inside because how light it actually was. Can't wait to get my build going. Tomorrow I will be pinning and welding the muzzle brake on.

Just some guy


Like this barrel very much. I haven't wanted or needed to return anything to Tactical link. I feel like they sort out the poor and sell only quality.

Holy Lightweight!


I had a 20" HBAR on my rifle. I swapped to this faxon barrel because I wanted a different setup. This barrel is amazingly light. It is accurate, but does heat up fast and the accuracy goes down from there. It does cool off quickly though. I do not suggest 'excessive rapid fire.' Id buy this barrel again for another build.
