|This stock is of excellent quality. The holes are pre-drilled with steel threads for the screws and is very secure.
The only reason it gets 4 instead of 5 bullets is the size. I have an old Norinco AKM and the spacing doesn't fit my tang. However, it is such a sturdy design it only needs the base screw and this thing is rock solid.
It required a small bit of filling to fit my stamped receiver. I had a different tube from another company on before that was so flimsy, and the screw holes were just drilled into the polymer, they eventually wore on consistent fire and came loose. I've put about 500 rounds through the gun with this new one and it's still perfect, thanks to the metal threads.|
