Not easily adjustable - Mission First Tactical Restricted State Compliant Buttstock

I ordered this stock new. I like the design. When it arrived, I found that it was cut open and look to have been returned. It did not come with directions. After playing with the stock for a little while, I realized there isn't a spring on it. There is a pin that locks into the buffer that freely moves up and down. It's down when you get it. Then you set your length. Push the pin into place using the lever/button. An opening will align in the stock, and you will see a pin hole running through the stock and the pin you just moved. Next you take a separate pin and push it through the stock/pin that locks into the buffer. If you need to adjust it for someone else, put it away, etc., you have to remove the pin. Drop the other pin to unlock it from the buffer. Move it then reinstall the pin. Thers is nothing easy about it.
