I have an RCR that is pretty well documented. I love it. That being said, when you pay north of 100K for a GT40 they are all pretty nice. Jeffko, come down to St. Louis this year to Run and Gun. You will see the RCR, Supermance, RF40, and the new BDRGT all in one place. Then you can look at the details that are important to you and make your decision.
