Great shooting barrel.
I have used several Faxon barrels, this one was a particularly good shooter with M855, 3/4" at 50yd, red dot, off a bag. The gunner and pencil barrels are soooo sweet. I dimpled this one for a gas block, just wish they came dimpled factory. Highly recommend.
USGood lightweight barrel
The barrel arrived in a beautiful gloss black and installed like any other barrel. It is noticeably lighter than other 16" barrels I've used. I don't have any complaints or concerns about it so far.
USFaxon 16" pencil barrel
This is an excellent barrel. No only every accurate but also lightweight. I definitely recommend this barrel.
USNice barrel
Accurate, light and sturdy...what else can one ask for.
USFaxon pencil barrel
Like all Faxon barrels I have the quality of the barrel is excellent. I haven’t shot it enough to make a judgment on the loss of accuracy when the barrel gets hot like everyone claims. Hot or cold it is as accurate as I will ever need it to be. It is pretty light and that’s what I was looking for , I think a tad bit over a pound.
