Even the CRF models of the last 15 years seem to be finicky with ammo/quality/fit. I have seen good ones and bad ones.
I know I had experience with the coyote model. And I can say out of the box, you might as well ship to a smith to have the full treatment done. Lugs lapped, crown cut, head space checked and possibly reset, glass bedded, trigger adjusted. Then after all that, it was a good gun.
But I will say this, even though out of box it may not be great, you still have a great foundation for a rifle.
