Looks possibly like Choate Machine and Tool 7.62 M14 style make by Choate for .223 Mini-14 some years ago. They still make them in Stainless $55.00 and blue $50.00. Click on their Cage model and below it click on small word "Ruger" for all models to appear. Hope this helps.
I’m new to firearms and only have bought a bolt action rifle. Can anyone give me tips on buying a used mini 14? I’ve never held one so I want to know what to look for and how to check the barrel (since there is no bolt to remove).
Pardon my ignorance. Just trying to learn here.
