So I’ve been doing a whole bunch of research and trying to figure this the hell out, hoping you guys might have some input.
My goal is to have a custom barrel made, the custom aspect includes cutting 2” off and rethreading, and dimpling behind the gas block.
Where I’m running into trouble is that i want to nitride the barrel. I’ve come across threads discussing this and half the people say they have it done no problem, and the other half say that their barrel extension became loose afterwards and at best was a PITA to fix, at worst a total wash. From my understanding the problems occur if the extension is a different metal type than the barrel and the heating/cooling of the process loosens it up, and/or if the extension wasn’t properly torqued to 150 ft/lbs
I contacted H&M nitriding who have done a ton of barrels for individuals and OEM stuff, and they said doing the whole barrel is GTG.
Has anyone had a full barrel nitrided with success? The other option could be get a rifled blank and have all the mod work done, then nitride, then have extension installed + gas port drilled.
No smiths I’ve contacted will do the barrel cut/dimple on an already nitrided barrel because they say the hardness will destroy their tooling equipment, which only leaves the options I’m looking at here. I don’t mind spending the money, I just don’t want to end up with an expensive piece of worthless metal.
Appreciate any advice/knowledge you may have
