I am trying to compile information on how these guns are assembled. I am interested in what lower, upper, barrel, etc is being used. Especially the barrel.
Please post pictures of MK18 MOD1s in military service with DD RIS 2 handguards if you have any. I am also needing any govt or factory information that says how these guns are assembled.
Please do not post pictures of your personal quasi MK18 MOD1 build or delve into any other side aftermarket topic.
I am only interested in real US military stuff.
