Did a search and I couldn't find a thread on this already. I know there is a discussion of the new finish version of the Gunsite, but I think this is a completely different rifle.
Ruger has released a compact bolt gun similar to the Gunsite that is chambered in heavier calibers for guide gun service. Has a muzzle brake, adjustable buttpad, etc.
It's a cool-looking gun, but how fast could you cycle a bolt in the intense, close-quarters circumstances a guide gun would be used in? Haven't all guide guns been lever-action previously? Maybe not, I'm pretty ignorant about rifles.
Here's the gun:
