There is nothing wrong with the Turk Actions, they perfectly suitable for building a rifle. If you like you can rethread a Remington barrel to small ring threads. Can't do that on a large ring thread. $150 is a bit high for a sporterized Mauser, but not bad if the action is in great shape.

You might try and look for a VZ24. There are mountains of them around and they can be usually be had for under $100.
