Quote History Quoted:I was thinking about what I'd do if I found a cheap A3 stock, because I don't have a lathe either. I think I'd get some nylon rod of the right diameter. It's cheap and easily manipulated with hand tools.
Something like this. View Quote
Good find and cheap as well.
I was looking at these adapters last night. I figured I would cut off most of the material but leave the "lip" and then install it backwards. That lip would be away from the weapon and keep the tailhook from sliding backwards.
I am 2 months out from getting an MP5. If in that time the SB Tactical hit the shelves at $150 I might be tempted to sell the tailhook and A3. I have the folding SB Tac on an Z-5P and its been great.
EDIT: Since there is a hole people are filling it! Just found these guys. They will modify your
4 Position ATI stock only for $65. You add a tailhook.
