Most Helpful Positive Review 10.5” stainless 300 blackout barrel
Amazing looking barrel. Shoots well. Had a slight issue where my Aero precision upper receiver feed ramps we’re slightly lower than the barrels feed ramps. Created a lip where the nose of the bullets would get stuck and not feed. Took a couple attempts with a dremmel and a grinding bit (think chains...

First time try. Works amazing well.

by Aaron L, Verified Owner from MD, United States Written on July 22, 2024
I used this Trybe Defense 300Blk barrel for a recent project. This was my first time using this brand and I already love it. Shoots very flat. I matched it with the Trybe Defense BCG and it works really good. I will be using this brand in the near future. Thanks.
Pros:
  • No Issues
Cons:
  • none can see
Best Used for:
  • Best use with compensators for accurate shooting.

Decent barrel for the price!

by RDG, Verified Owner from AZ, United States Written on March 15, 2024
I needed a barrel for an ar build i was doing in 300blk Trybe makes a decent barrel at this pricepoint. It does not come with a thread protector i installed a brake on it so no biggie but if you dont plan on suppressing or adding a brake youll have to buy one separate.

Great for the price

by FreedomEagle, Verified Owner from AZ, United States Written on January 15, 2022
Sturdy barrel that is hard to beat for the price. Have not had any issues yet. I probably wouldn't throw it on an expensive build but if you are building a sub $1,000 AR this will do the job just fine.
Pros:
  • Price
Cons:
  • None
Best Used for:
  • Mid range builds

Great looking barrel.

by Jon, Verified Owner from GA, United States Written on May 20, 2021
I have only test fired one round. So, I cannot comment on accuracy. What I can say is the barrel arrived in good condition with thread protectors installed on each end, and the finish, threads, and feed ramps look very well done.

The only issue noted is related to the receiver made by Aero that I am using. The barrel extension ramp cuts overhang the Aero Receiver Ramp cuts by a small amount. I have seen this issue mentioned in two other reviews, and can confirm it is a possible problem. However, after testing the feed of my preferred bullets from a Magpull magazine, I have noted that the bullet tip does not impact the combined ramp surface below the barrel’s ramp. So, it seems to be a non issue. This issue may actually be an issue with the receiver and not the barrel—-I do not know.

I will update this review if any remarkable accuracy (good or bad) is noted, once the entire build is completed.
Pros:
  • good price
  • well balanced
Cons:
  • None
Best Used for:
  • short range hunting
  • Short Range target
Would recommend: Yes

300 black out barrel

by brucekey, from VA, United States Written on February 13, 2021
This product has a great finish and accurate. I had it installed and swiped out a 556 barrel on my DDM4V11. (Daniel Defense) with a primary arms gen 3 scope. It is now my favorite riffle next to my 556 Spike Tactical pipe hitter.
Pros:
  • Great Price - BUY IT
Cons:
  • None
Best Used for:
  • Hungting

Great groups!

by trigerhapy, Verified Owner from TX, United States Written on September 25, 2020
Definitely happy with this purchase. After a brief break-in this barrel is giving me 1" groups at 100 yds using 120 grain Remington UMC ammo. With my hand loaded 190 grain subsonics it's grouping 1/2" at 100 yds. It's a hoot to shoot! Finish looks great and the fit is perfect. I didn't run into any feed ramp issues that another reviewer had. Maybe I got lucky with the upper receiver I used.
