Most Helpful Positive Review 350 Legend Faxon Barrel
Excellent customer service. Super fast shipping. Competitive price. This barrel was for a build and I must say I am beyond pleased. Very well-made and very accurate with factory ammo. I wanted a light rifle for hunting and the Gunnar contour fit the bill. The rifle handles very well and consistently...

Most Helpful Negative Review Missing information
This barrel is made for rifle ramp uppers or big bore uppers, not m4 ramps per faxon as I found out after assembling and test firing. The barrel sticks past m4 ramps and destroys soft tipped bullets when chambering. It also wasn't dimpled for gas block install which would be nice. Apart from that th...

It's a big bore extension with a single feed ramp.

by Kevin, from IN, United States Written on October 19, 2025
So it will not work in a standard AR upper. It is also NOT meant for a 308/AR-10 upper. Just trying to clear things up for others. There are other 350L barrels that are not big bore extensions yet still have a single feed ramp - and these will work in your standard upper.

350 legend

by rick, Verified Owner from WV, United States Written on February 14, 2025
works ammo through with no jams. I believe it's due to the single feed ramp instead of standard m4 type.

Accurate barrel

by Dalton Atwood, Verified Owner from OH, United States Written on September 28, 2024
The barrel with the big bore feed ramps makes it reliable in the ar platform. Im shooting a .6 moa @ 100 yds. I own alot of faxon barrels and they never disappoint

incorrect gas length-Pistol, not carbine!

by D, Verified Owner from TX, United States Written on December 28, 2023
I can attest that this barrel is pistol length, not carbine length like it says. Unfortunately I didn't find this out until I assembled the gas block, gas tube, and attempt to install on the barrel.

Other than this, it seems to be well made. I can't write a review in how it shoots as I was given incorrect information. If this barrel is anything like other Faxon barrels, expect a break-in period.

Very accurate and easy to install

by Jmanz6, from MI, United States Written on September 29, 2023
I purchased this barrel for a 350 Legend build for deer hunting in Michigan. The barrel was high quality and was easy to install. The accuracy has been great too.

Does not fit M4 upper

by Johnnie, Verified Owner from MI, United States Written on November 26, 2022
Nowhere in the product description does it state that this is for a .308 style M5 upper. It doesn't fit my Aero M4E1 upper. Pretty disappointing finding this out during assembly. Hopefully the return process isn't too painful.
Pros:
  • None
Cons:
  • Missing information

350 Legend - 20" Gunner - Well worth it

by Mike, from MI, United States Written on October 25, 2022
Bought this and a BCG to replace the GLFA factory original. This barrel has a much smaller gas vent and I was skeptical with cycling. To be sure I did dimple the barrel although Faxon suggests barrels should not be to avoid corrosion opportunities. I'm currently a few hundred rounds and have cut group sizes in half. I will definitely lean towards Faxon products for my next AR build.

Avid hunter, Light gunsmithing

by Thor, from MI, United States Written on December 1, 2021
Sub MOA 16” Gunner profile 350 Legend barrel ***** the Gunner profile barrel on AR platform rifle with Faxon carbon fiber handguard is the absolute most comfortable rifle I’ve ever carried. I would recommend this ultralight combo to anyone thinking of hunting with an AR platform rifle.
Pros:
  • Lightweight, excellent balance
Cons:
  • None
Best Used for:
  • hunting

Good Barrel

by Slow Fat Guy, from NC, United States Written on November 13, 2021
Bought for an easy to carry brush gun for AR platform. So far so good. 200 rounds through on first day at range with zero problems. Grouping between .9-2.5 MOA at 100 depending on ammo. I have a 16” 6.5 barrel just like this and it is very accurate. These gunner profiles have good balance of weight.
