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 in-house, 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.

    Great Barrel for the price

    Posted by Kyle on Sep 6th 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.

    EXCELLANT BARREL, EXCELLANT VALUE

    Posted by Unknown on May 17th 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!

    Incredible Find!

    Posted by Thumper on Mar 24th 2016

    I was looking for the shortest barrel with a Middie gasser, and this one is perfect! Just one word of caution - given the short dwell time, you must be ready to utilize an adjustable gas block (whether DI or Piston) and spend some time adjusting the system to work reliably. This will especially be true if you plan on any QD-Type Silencer mounted on it. A fixed mount silencer is probably your best bet if you are going this direction... This is the only barrel for nearly all of my shorty builds now!

    Awesome SBR barrel!

    Posted by Unknown on Mar 15th 2016

    This is exactly what I've been looking for. I wanted to replace my BCM 16" mid-length lightweight upper when my SBR got approved. It's running perfectly so far (300 rounds) with an SLR Sentry 6 adjustable gas block (setting 7 from closed) and Surefire Socom muzzle brake with Federal XM193. Running an m16 BCG and standard CAR buffer. My rifle now 14 oz less (9oz is barrel, the rest is from the lighter handguards) than before. Even with the reduction in length and velocity, accuracy is about the same. I can still bust clay pigeons at 100 yards with ease. With the brake, the blast and flash are obnoxious though. Still waiting on my Socom 762 mini. The value of this barrel is outstanding. Even considering the cost of an adjustable gas block, it's still cheaper than a comparable chrome-lined barrel from BCM. This is THE barrel to get! On a side note, I killed a brand new titanium drill bit trying to dimple and pin the gas block. A cobalt bit and drill press was needed to get through the QPQ finish.
