You pulled the adjustment lever down (away from the stock) and then tried to push or pull the stock and it did not move?
I have a NY compliant fixed stock. Trying to take it apart to install the FRS15. Can't get the castle nut off and how do you remove the stock pin? I do have the Tapco wrench but I can't seem to break it free. I do see that the castle nut has two "stakes". As you can see this is going well..........can anyone provide any insight?
Great chance to dump the crappy Tapco stock and upgrade to a Magpul or MFT.....just my .02
