Tdi arms akst-ak47 buffer tube - Tdi Arms AKST-AK47 Buffer Tubes

This is a very well made and good-looking buffer tube. It works with mil-spec stocks and makes the AK platform more modular and flexible. It was a tight fit on my WASR-10 and required some tapping in with a rubber gunsmith hammer. I oiled up the inner receiver tang area and the tube mount to help it find its home. The receiver and tang holes lined up perfect on my rifle. Once secured it is rock solid and actually looks better than the AK itself.

That being said there is a lot of tolerance variations across different AK makes and manufacturers so what works on the WASR-10 may not work with a PSA, Arsenal, K-USA or whatever. I have a Romanian RH-10 and it was a no go for that firearm. I recommend doing a side by side to ensure the tube and receiver holes match up and the receiver will accept the buffer mount with minor tapping installation before taking the chance of marring the finish and not being able to return for refund.
