I just put together a 6.5 grendel AR and it is extremely hard to chamber or extract a round, is this something that will just smooth out with use or is there something I can do to speed it along.
No gas tube or gas key so that's not it. It's got lots of lube, could need to be broken in. How could I tell if it's the extractor or locking lugs? I am using Wolf Ammo, it's what I could find.You could try polishing the chamber with some Flitz after ruling out everything else first and don't overdo it. If that doesn't work it will cost more to fix it than to get another Bear Crap Arsenal Barrel.
List of other potential problems that could cause this.
Misaligned gas tube,
Out of spec gas key, (had this happened with a factory-built AA grendle)
Out of spec. extractor,
Lube and break-in time
Mis aligned locking lugs (factory problem)
Headspace (Factory problem)
