Most Helpful Positive Review Surprisingly good
I was looking for an inexpensive tube for a budget build. This buffer tube is nicely machined. Very nice coating on the inside and very smooth on the outside. My SBA3 and SBA4 slides really smooth and clicks into the 8 positions nicely. Fluting looks great.
Most Helpful Negative Review It's a decent buffer tube but....
Decent buffer tube, has a really cool design, and didn't have any issues but one.... Unfortunately it's as deal breaker, I don't like being swindled. When you advertise a buffer tube made from 7075 aluminum but I receive 6061 aluminum, even if the product t good quality, it's not what you told me yo...

it looks great but the inside machineing is horrible

by twin armory, Verified Owner from TN, United States Written on July 3, 2025
I got two of these. They look cool and that’s why I got them because strike industries was $20 more. The Down side to the two I got was the inside of the buffer tube on both of them is a little rough. It won’t stop them from working it’s just an annoyance. It makes using Maxim defense ROLLER DELAYED BUFFER (RDB) SYSTEM for 9mm harder to charge back. The system is already hard to charge back but the added friction from the inside of these buffers tubes makes it even harder. I won’t return them because they still function and will work pretty well with a standard buffer system. And hopefully over time it will smooth out after a few hundred to a thousand rounds
Pros:
  • Looks great
Cons:
  • None
Would recommend: No

I have purchased a number of these and I really like them

by David Skaggs, Verified Owner from ME, United States Written on June 4, 2025
I have purchased a number of these 8 position buffer tubes and I really like them, they are well made and I like the ability to fine tune my length of pull on my rifles. If anyone else uses the rifles with these on them it’s the same story, they like the ability to select the best length of pull for themselves. My grand kids seem to be the ones that really notice the difference in the finer increments as opposed to the rifles my son has that are six position. Sometimes it’s the little things that make the biggest difference in life. Be safe, life is to short as it is without hurrying the process.

Not bone stock

by Bluoval75, Verified Owner from TX, United States Written on June 5, 2024
I like the look of the tube not just a round buffer tube. Texture is a little rougher than most but doesn't effect function.

nice for a flashy 10/22

by Q, Verified Owner from MI, United States Written on August 18, 2023
The blue color and fluting looks very nice but be advised that the fluting will open up clearances and allow your stock to rattle on the tube unless you apply something to prevent rattling. I used a bit of velcro
