Reviews & Ratings for FAB Defense Collapsible Buttstock Tube for AK-47
— 4 reviews — Page 1
So thank God for Chucky’s review because he is 100% correct that this buffer tube is in fact commercial spec.

This thing is garbage. Filed on it all day very carefully so it'll fit and no success. There's not enough plastic on the part that mounts to the receiver after filing down for fitment.it uses a tiny plastic wedge on a screw that expands your receiver out to hold itself in place with pressure. Spend the money and get yourself a mil spec buttstock. Thowing this thing in the trash.

I purchased this tube along with the FAB Defense Core-CP stock to install on my Saiga AK. Be aware this is a commercial-spec tube (not mil-spec). Its very well built and I really like the recoil reducing spring action. The FAB Defense Core-CP stock comes with adapters for commercial or mil-spec tubes so fitment was not an issue.
