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.

*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 was excited when I saw this barrel. I tinker with suppressors a lot and I'm always looking for the next best thing for tuning. I was able to set this up in an aero receiver set with a SLR gas block, lightest SCS buffer and a saker 556. That setup was the softest shooting upper I've shot. Very little recoil, nice pile of cases 6-7' away at the 3-3:30. BUT the gun ran absoultely filthy. After about 40rds, evertyhing was covered in fouling. I tried the superlative gas block with the blow by screwed out as far as it would go. I've got the adjustment screw touching the back of the suppressor now. It's not all the way open, but it's close. Even with the blow by that far open, the new setup ejects the cases 10' to the 1:30, that's with a SCS with 3 tungsten weights. I can't go any heavier on the buffer without getting creative and I can't open up the gas glock for the blow by without milling out a part of my suppressor mount. The gun doesn't shoot terrible but it's overgassed. The superlative setup does run a lot cleaner. Not sure a smaller gas port would help my situation but I feel like it defeats the purpose to have a barrel for "use of a suppressor long-term" with a large gas port on it. As an end user, it's easy to open up a gas port if I need more pressure. Whatever, you can't please everyone. Barrel has shot fine and I've had no issues with it or the install.

    If you are looking for a quality barrel that won't kill your build budget you will not be disappointed! The 11.5 is on my patrol rifle and I trust this with my life!

    I built an SBR utlizing this barrel. First time out to the range I was banging an eight inch gong at 200 using a red dot. I also ran a few mag dumps with the Fostech Echo Trigger supressed and unsupressed. FLAWLESS! I am so impressed and glad I bought it.

  • Fantastic barrel.

    This barrel is amazing. I was worried about the dwell time and due to being short on cash I opted for the low profile gas block even though Faxon recommends an adjustable one. Still works great. This went on a pistol build. Haven't had any issues as of yet. Runs like a champ. The craftsmanship on the barrel is top notch. It has a very nice finish and fit into my aero precision M4E1 upper receiver perfectly. I haven't been able to do any long range accuracy tests but at 25 yards this barrel will get you 1 inch groups or smaller if you're a better shooter than me. Not much else I can say other than I would buy this barrel again in a heart beat. Faxon was a new company to me. I will likely buy from them from now on when it comes to my barrel needs.

  • Excellent for lightweight SBR

    So far I've been extremely happy with this barrel. I used it to build my lightweight(ish) SBR and have absolutely no complaints. Since it is on an SBR, I'm not terribly concerned about long range accuracy but rather practical accuracy. I haven't shot it past 25 yards yet, but I have put about 500 rounds through it and have been very happy with the results so far. I highly recommend it for this use case.

    Swapped this into my SBR and shot 60-90 rounds through it surpressed. I run a spike ST-T2 buffer and I experienced zero malfunctions. . Barrel feels good in the hand and the weight feels great installed under my 10.5" Midwest rail. Would reccomend to a friend looking to surpress a rifle.

  • Finish and quality look great!

    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.

  • Great concept, not for everyone, excellent execution

    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
