The only reason that vertical grip is on my WASR10 is so I will have something to hang on to when I use the T6 bump stock from the shoulder. I personally hate vertical grips, but after my last bump session where I grabbed it tight when it got going and one finger slipped through the handguard slots and touched the barrel, well it it's almost healed now after 3 weeks!
That's as far as I am going to "Tapcorize" the M70. I would have prefered the FN original grip but the mounting is slightly different inside. It's made of hard rubber, not hard plastic as the Tapco version is. Still, it fits the hand better than any other grip I have ever felt.
And the T6 stock, well, who says an AK has to have a 2x4 hanging off the back of it? Plus this one is "spring loaded" for shoulder bumping assist. Plain and simple, it works! Like the Yugo rifles with BHO mags and notched selectors from the Factory, it's an improvement in my book and has Factory approval. If you look carefully both of those AK's have notched selectors and ALL of my mags are BHO's. It is so wrong to pull the trigger and hear, "click, you are dead".
