Total AR noob here trying to remove the stock to install the ACR stock and adapter.
I just want to make sure I am doing this right: To remove the stock I need to loosen the castle nut and slide the retainer back to remove the buffer tube that is not actually a buffer tube is that right? The castle nut is quite tight on my rifle, I already marred the soft aluminum threads a bit with the armourer's tool. Next step I can think of is to put the pistol grip in a vise for support and maybe heat the castle nut area with a heat gun assuming it has loc-tite on it.
Am I missing anything here about how to remove the darn thing?
