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.

The buffer tube is a good affordable piece to complete your build, I have ran about 500 rounds so far with zero issues. I will buy again for my next build.

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.

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.

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.

High quality and light weight. Good fit to the adapter I chose. Also matched up well with the SBA5 pistol brace. Definitely recommended.
