I am surprised to see little in the way of conversation over the RFB? This was one of the few threads on THR to actually have RFB in the title.
Who was Kel Tec building this thing for? I take it the civilian market for sure. Don't think any of their products have actually been serious military contract contenders. I have a weird thing about guns in clamshells that come apart by removing a series of screws! And PLASTIC clamshells at that!
I used to have a Kel Tec Sub 2000. Fun gun, but in the end, I prefer firearms that have the backing of years of experience and a design that was intended for serious work. I gave up the Sub 2000 for a Wiselite Sterling. I used to own an actual Sterling manufactured Mk 6. Once I had confidence in my Wiselite, I sold my Sterling at a nice profit and have now put thousands of rounds through my Wiselight 9mm sporter and have had a great experience.
I like a gun that has a proven track record. Even if it is an old MAS 49/56 or Springfield Armory M1A....they have been proven in combat.
I LIKE the concept of the RFB, but am left a little cold by the execution of the design. Not to totally trash Kel Tec , I am sure the engineers put some very good theory into practice. It will just take a while for me to be convinced of that rifles validity.
