I keep coming back to this idea, I really like the thought, but couldn't come off the money for any of the options I listed here.
First thing to go was the left handed bolt. I can run a right hand bolt just fine, I just liked the idea. Besides, if I hate the gun, a right hand bolt will be easier to sell.
That got me to a Mossberg MVP Patrol, but I put my hands on it and it was pretty awful to run. Just a lot of play in the bolt, enough that I could easily induce malfunctions in feeding from a mag, also a "meh" trigger, and a overall cheap feeling.
After that I came off of the .308. That cartridge did two things: It made it hard to get the 16" barrel I wanted from the factory, and it made mags expensive and capacity limited (AICS), proprietary (Savage), or proprietary, low cap, and shitty (Ruger rotary mag).
I reread all your advice on here about what I was *really* likely to be shooting, and I shot my friend Ben's rifle, and decided for east-coast US, .300 BLK will do me. There's a wide variety of available loadings, it has plenty of range for a human/predator defense rifle, and it really helps the rifle fit into the small, light, and handy idea.
Then after scouring used markets and gunbroker, I found a NOS Gen 1 Ruger American Ranch in .300 BLK for $375 with free shipping. It was the last one this shop had, everyone was buying the Gen 2's now, and he just wanted it gone. The Gen 2 has some nice upgrades but seems to be $600 minimum everywhere I look. I fondled the American earlier in this journey, and I will have to do a little work to make it work for me, but it is all pretty much DIY work, or cheap to do, and for that entry cost, I can do some work to make this project come together.
Gun should be here this week, and I ordered a LPVO to go on it. We'll see if I can make this project finally come together.
