Chucks is right - FAB Defense Collapsible Buttstock Tube for AK-47

So thank God for Chucky’s review because he is 100% correct that this buffer tube is in fact commercial spec. After measuring it numerous times and with different tools it measured consistently within the 1.16 parameters which is most definitely commercial spec. Having said that it is still a fantastic piece of equipment which when coupled with the proper commercial spec stock will give you a better recoil and less of a bruising when shooting at the range for long times. Thanks Chuckie and Ethan get your facts straight.
