Most Helpful Positive Review Epstein didn't kill himself
So i used this on a AK with the strike force adapter. It looks very good and matches the B5 grey color nicely. Ill buy another if i do a grey theme again. Shipping time from Optics wasn't bad either.
Most Helpful Negative Review Aluminum is very soft
I would avoid this buffer tube due to the 6065 aluminum. It is way to soft and the threads strip very easily when tightening the castle nut. Had to return the one I purchased and went with another buffer tube that was 7075 aluminum and didn’t have this issue.

Great fit and color.

by AJ, Verified Owner from CO, United States Written on April 15, 2025
This fits perfectly and the color is great. I'm trying to get this build to be as close as possible to same color for all components without having to paint them all and this is really close to Brownells aluma Hyde coyote.

Way out of spec

by ThyToaster, Verified Owner from KS, United States Written on March 25, 2025
I bought this tube expecting it to be milspec as the name suggests. The 6 position holes were poorly drilled and the tube wasnt concentric. It was thicker on the bottom which was letting the buffer sit higher and slip over the retainer. This could just have been a fluke in the production chain, but milspec is literally the bare minimum so it's pretty disappointing when it falls short.

No notch for the retainer spring

by Spence, Verified Owner from OH, United States Written on October 4, 2024
This has no notch for the buffer tube retainer spring. So you have to screw the buffer tube into where it will hold down the buffer retainer. If because of the way this one works it was holding down the spring but not by enough according to my range time. Major Malfunction while shooting, the spring came out while the BCG was in the tube. This ejection, caught the BCG not allowing it to come forward. Upon examination, this buffer tube won’t allow another turn because it hits the peg and won’t allow 1 more full rotation. So you have to back it up by 1 spin. The placement holds down the retainer spring but it not enough, the vibration of shooting will set it loose in less than 5 shots.
Would recommend: No

Notch not machined for retaining pin

by Stan, Verified Owner from NC, United States Written on August 16, 2024
The buffer tube was not machined to have a notch to catch the retaining pin. It’s going back and I will order a better quality part. Tried to save a little money, but you get what you pay for.
Pros:
  • The finish looked nice
Cons:
  • No quality control
  • Not a complete product
Best Used for:
  • Paper weight In its current condition.
