Hello,
I have a NJ compliant LMT MRP CQB AR-15, which includes a Sopmod stock. The LOP is adjusted via a bolt that needs to be turned with a hex key. I'm wondering if it's legal to remove that bolt, and replace with a thumbscrew that will no longer require a tool to manipulate. The reason is because I am 6'4 and my fiance is 5'6, so naturally I would like to adjust it according to her height when she's at the range with me.
Thanks in advance.
