Modifying 6920 upper
I have a question as far as this goes as well, better to ask in here than start a new post... I was a fairly competent mechanic before I became an EMT assuming I can stumble across all the barrel nut torque specs and I already bought a vice block dpms multi tool front site base block
how difficult of a change over would it be to put a 15'' nsr on this thing I have a 6920 as well? Is it simply as easy as punching out the gas pin front sire post pins removing the barrel nut, taking my barrel to adco (local to me ) have them pin the low pro gas block. I feel confident up to this point for sure... But re-installation is where I hear problems come in from head spacing... Is this something that can be done with out the proper feeler guages with the factory barrel easily?
