After a great deal of research, I determined that they are little more than "dressed up" Auto Ordnance/Kahr carbines. (Talk about a disappointment). I have changed my mind and will be saving my shekels for an James River Armory "Rock-Ola" M1 Carbine. Since both the receivers and bolts are milled from billet steel, their longevity should be substantially longer. Yes, it will run me $1300.00 but with a Criterion barrel, the better accuracy provided by all of the parts working in concert should be worth the expense.
About the cast boolits being fired in the M1 Carbine. What kind of alloy would you recommend so that some expansion at the boolit's meplat can be attained? Is this possible, or is it just a pipe dream?
Say it isn't so!
