Just the standard- I talked to him after I ordered it and he machines all his stuff in-house. When I was waiting for my stuff he told me he was waiting on metal. Got the slightly longer firing pin for commie ammo. I've got a couple of 7.62 ARs and really all I had to do was bug J4 a little bit and open up the gas port hole a little and they both scream! I kinda like talking to the guy who actually makes the parts.
