Check out the "Sig Rifles" subsection of the "Armory" on ar15.comHas anyone ever removed the end cap from the back of the receiver on a SIG 556 pistol? If so, how did you do it and how tight was it torqued on? I got my form 1 back for my SBR and I need to put a stock on it. I'm thinking of making some sort of spanner wrench to remove it. Thanks
I AM ALSO IN THE SBR PROCESS FOR MY P556, I MADE A WRENCH FOR IT, THE END PLUG IS VERY TIGHT, I'M THINKING ABOUT MAKING AND SELLING THE WRENCH, I DON'T KNOW IF THERE IS A LARGE ENOUGH DEMAND.
