Designed for those looking to save weight while still allowing for the use of a suppressor long-term, the BIG Gunner is ideal for suppressed shooters. All for just about a single pound!
Behind the gas block will be a Government profile tapering to a shoulder and 1.1" journal .625 gas block. In front of the gas block, the barrel will continue straight to a 1/2x28 muzzle with full shoulder.
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.
Faxon manufactures all our barrels in Cincinnati, Ohio under our ISO:9001 and AS:9100 quality certifications.
*As this barrel is likely to be used in full-auto applications, we are opting to stick with a 5.56 chambering to ensure absolute safety for our customers.
**Due to the short dwell of the barrel, the gas port will be larger than most barrels. Customers are encouraged to use an adjustable gas block for optimum functionality.
I haven't installed it yet but other Faxon barrels we've used are very accurate and the finish on them is top notch. I expect this one to be the same. Unknown on 15th Dec 2016
I was intrigued by the idea of a mid length gas sbr and was excited when I saw faxon firearms, my favorite barrel manufacturer, implement it in a 11.5 form factor. This is as short as a mid length gas system will allow.
I decided to pair this with one of the newer superlative arms piston systems, and wow am I glad I did. I was initially worried about gas port size and if the short dwell time with a piston system, but it has worked out great. First time out I was able to dial the gas adjustments in quickly and found that the recoil and violence of the action compared to my 10.5 carbine direct impingement was greatly reduced. In combination with the bleed off function of this piston system really makes for a soft shooting well balanced rifle.
Accuracy is equal to my other faxon barrels, barrel length considered. No problem with 8 inch steel plates out to 200 yards (about all this rifle will ever need to hit). Thanks for your hard work faxon! Keel up the good work Nick Wood on 22nd Sep 2016

For the price this is an excellent barrel. Lightweight and the finish is spot on. I will try to be as critical and fair in this review as I can.
There is no need to a gunner profile for a barrel this short. A regular GI profile would have been fine, the weight reduction for the inch and a half of barrel after the gas port is very little savings. This does allow you to use a smaller gas block, but the smaller diameter, also means you can't use existing gas blocks and the selection of adjustable gas blocks at this diameter is poor. I feel like the gunner profile for this barrel has more cons than pros. I wonder what rigidity and strength are sacrificed at the end of the barrel for such a minimal weight reduction.
I do not think I need to describe the weight of this barrel, it is an absolute must to use a GI profile or Gunner profile for an SBR or pistol build. Forget about using a heavy barrel, you'll be front heavy and slow, any accuracy gains you'll receive will be negligible with a short barrel in my opinion. I avoid pencil barrels as I like to have a suppressor on my front end and I don't want my barrel to bend during moderate use.
I am not terribly impressed by the accuracy so far, though I've only shot enough rounds to tune my gas port and get this zeroed with my sights and optic. I am not disappointed with the accuracy either, remember when going SBR the typical goal isn't to have a rifle that can hit steel at 500+, it's to make a compact rifle that is light in the hands and can hit targets within 100-200m (or closer).
This barrel will fit the requirements, the finish seems durable, the accuracy is acceptable (I expect that using mk262 I may be able to squeeze out more consistent shot groups).
Good luck, I do not think most users will be disappointed with this barrel at this price. Kyle on 6th Sep 2016
We are using Faxon Barrels exclusively on our Takedown SBR AR rifle builds. While I planned these as last ditch close in personal defense weapons, I was surprised at the accuracy we're getting out of this short, light barrel! With an adjustable gas block (as recommended), a Titanium bolt carrier and short muzzle brake, these guns are a pleasure to shoot!
I can recommend Faxon Barrels without reservation!
