"Bushmaster Modular Accessories System 3 Rail Gas Block Set" is what I have on my 16" BM upper.
I love it, but am now wondering how to remove it. I may or may not be having gas-system problems. (I'll find out tommorow).
If I have to remove the gas tube, I am clueless. From my understanding, I need to remove the gas block, but the documentation I can find is, of course, for the standard A2 block, not my BMAS.
Anyone have one of these and know how to remove it?
