So I'm refinishing/building my AR10. I end up running into some fuckery with the rail not being able to come off over the gas block, which is low-pro under the rail. So after loosing the screws and attempting beat the block off and failing miserably, I decided I will just buy another block and cut the current one off.
So I get it cut off, and realize there is a red hard material around the gas-block seat on the barrel. Looks just like dried red loctite.
Has anyone ever seen or heard of this being done before? Freaking new to me, and really wondering if that's common practice in some shops. It's a Noveske barrel on an Armalite AR10, so someone custom built the thing. Anyways, very odd to me.
