Questions from
@PathFinder (the list part seemed to mess up the response format??)
**Does the Kimber action bring the same advantages a pre-64 M70 does in terms of reliability, or not? Is their trigger mechanically similar?**
I don't have much experience with M70s, but Kimber actions have been very reliable with a couple of caveats.
Early, pre-25K serial numbers commonly had some feeding issues, so avoid those if you’re buying a used donor. Kimber redesigned the feed rails somewhere between 21K and 25K and fixed that.
I've had light firing pin strikes on one. Kimber sent a stronger fp spring unit and that was cured. So very fixable if you were to run into it.
Their trigger is very different from a M70 trigger, especially the older M70 trigger. I think their triggers a very good. Their safety works a little different internally. They have a couple of patents on the changes they made.
**Any aftermarket detachable magazine bottom metal?**
Nothing aftermarket that I've seen, just their Hunter magazine.
**Any reasons to stay away from the Kimber? Certainly no prefits is one disadvantage, as is the lack of aftermarket support.**
None other than what you've listed, in my opinion. If you want lightweight, there's very little that competes with their actions.
