“What’s up with the Century head space problems?Is the trunnion stretching or the bolt lugs wearing fast?”
The RAS-47 has issues with heat treatment and hardening. I would say a few or some rifles only, but Century won’t say which rifles are affected. The locking lug on the bolt are deforming and creating enough of a gap to make some rifles go boom the wrong direction. I’ve counted six over over the last year and a half. Rob Ski from AKOU could give you the accurate numbers.
From what I’m reading and being told, it’s the soft steel in the bolt. The lugs are both wearing quickly and bending. In some cases it’s the front trunion doing the same thing along with the bolt, being soft and wearing quickly.
Several have verifiably grenaded.
The Century apologists and those suffering from cognitive dissonance will steadfastly refuse to believe the overwhelming evidence that Century is cutting corners on the quality and heat treating of those parts. They will cite guys like James Yeager claiming to let students fire the RAS-47 and have 10,000 rounds on a dozen rifles, no problem. That’s cool but it doesn’t actually refute the documented kabooms nor address Century’s response to individuals with kaboomed rifles.
If Century Arms had succeed initially, I would own several of them. Their C39V2 (in english that’s a milled receiver ak variant) seems to be slightly better but not enough that I would shell out for one and fire it up next to my face. Others obviously see things differently.
Without getting into the cast vs forged nonsense, the long and short of it is that Century Arms metallurgy apparently isn’t up to the job.
They might be better than IO though...
