Most Helpful Negative Review Poor customer service
I’ve built several AR’s but can’t get this 300 BO to function correctly. I’ve made several calls and emails to Odin and each time I’m assured a RMA is in the works, yet nothing. Everything points to a manufacturing defect, but who knows since I’ve yet been able to return it. Extremely disappointed in Odin’s customer service.

Perfect addition to my build!

by Michael W, Verified Owner from KS, United States Written on February 1, 2021
It works as designed. I haven't had to adjust the Gas yet on my 300BLK, shoots perfect suppressed or unsuppressed. Not for a sub-MOA rifle so I have zero details. But the price was great when I purchased summer2020. It was well packaged for shipping and mint condition when it arrived.
Pros:
  • Price
  • Gorgeous
Cons:
  • None
Best Used for:
  • Target & Competition Shooting

Top notch quality

by Ken M, from FL, United States Written on August 20, 2019
I recently purchased a DDM4 rifle in the 5.56 caliber and needed a 300 blackout barrel. I opted for the Odin works barrel because of the reputation and reviews online. I have to say this barrel was delivered fast and the craftsmanship quality is fantastic. The stainless steel looks like it is polished no tooling marks feed ramps are fantastic. As of this review I have not had a chance to take it to the range but with a borescope I can tell you the quality is even on the inside of the barrel. Will definitely look at other products from Odin works in the future.
Pros:
  • Quality of craftsmanship
  • Included adjustable gas block
  • Price compare to a Daniel defense barrel
Cons:
  • None
Best Used for:
  • EVERTHING

Great 300 blackout barrel

by Magnum, from GA, United States Written on October 15, 2018
Purchased the 10.5” barrel version to go on a licensed sbr. Barrel was delivered quickly and comes in a protective plastic tube with foam rings. I installed the barrel and left the gas block at it’s most open setting. Function was perfect using full power and subsonic ammo. Even using only a trijicon mro with no magnification. 1 got 1” groups at 50 yards. I’ll turn down the gas system a bit, as it threw empties about 15 feet. On my current setup with a slim midwest industries carbine length handguard, i would need to remove the handguard to adjust the pistol length gas system, unless u have some very long hex keys. Odin has a video on their website about how to adjust the gas block. Note that it comes with a gas block, but you must have a pistol length gas tube.

Robust and easy to install

by Kevin, from VA, United States Written on August 13, 2017
The barrel is the perfect twist for a sub-sonic load. The low profile gas block also enables you to have a small rail which a suppressor can easily fit within it. The only downside is if you desire the barrel to be blac it must be cerakoted as its current sheen sticks out.
