Not me.
I have met all the folks from Model 1 Sales that come out to the gun shows in this area, and they certainly seem like good folks to me. No matter how rude some customers act (Yankees) or how dumb a question someone will ask them, they just stay even tempered, level headed and polite, a lot better than most of us could.
They have a good selection at good prices.
If I was going to buy an upper today, that would be the first place that I would look.
I was not impressed with the one guy I talked to at the gun show in Fort Worth. I know those guys have been hammered at the gun shows and it is probably hard to keep a smile on your face but the guy just didn't impress me. I'd probably never buy anything from them based on that one interaction.
Rational? Nope - but consumers don't have to be. They have PLENTY of other options.....
