I had that same problem with the collapsable stock on my Saint AR15 also, I couldn’t get it loosened up so I put a Magpul stock on it. It has since been sold.New SA AR-15 SAINT Victor.
My collapsible stock is incredibly tight and requires me to use two hands and a lot of muscle to move. Is there any way to loosen this thing up so it slides easily?
Tried to free it up with a little lubricant and it didn't work.
Thanks.
