I had a 30/30 one on loan from a friend but decided I better buy one. I came across a virtually new 14" .223 just a few weeks ago for $360 which I thought was a decent price. I'm in the process of purchasing a EAB .357 Max barrel from RJ556. Too many guns, not enough paydays!
I have some plans for the .223 one, its gonna get a suppressor so the barrel is off being threaded now. Its gonna be a dedicated unit since my other one pretty much stays on my Mini 14 and I'd rather not switch them around a lot. Too bad the .223 one didn't come with sights so I haven't been able to shoot it.
Sadly I really don't know much about them, but when I order some Max brass I'll get a book too.
