Installing a stock onto your car buffer tube requires no tools, and can be done quite easily. I'd reconsider using it. I think your playing with fire.
Yes, you could be if you can't explain what the extra butt stock is for. It's the same thing for the Glock carbine kits. The stock just attaches to the Glock's extra grip well, after you install the 16in barrel. However, I will go the extra mile and buy a pistol tube. By the way, even with the pistol tubes, you can still slip on an A1 or A2 stock.
