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.

Buffer Tube

Everything is great about this product except there’s no cut-out for the buffer retaining pin to sit in. I was able to use a file and make one.

Exact fde color

by Moose, Verified Owner from IN, United States Written on July 31, 2025

Great buffer tube, doesn’t leave slide marks from stock, and exact FDE color. No 50 shades of FDE here!

AR 15 parts

by Wolf, Verified Owner from NY, United States Written on July 22, 2025

Great part fits exactly like it should the coating on it is very good. Processing of the order was a little slow in my opinion

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.
