Well, I just got bent over a barrel. I've done business with http://www.classicfirearms.co/ and they were great people until now.
I called the owner on 03 May to ask if the the Saiga 7.62x39 20" (IZ-131) they had happened to have stepped chambers. The Russian government requires this for civilian rifles, to help identify the weapon used during a crime from the small swell it leaves in the case neck. While the brass can be reloaded a few times, sizing eventually takes its toll and case ruptures happen.
The dealer pulled one and inspected it for me, and said the chamber step was definitely not there. The rifle arrived today and wouldn't you know it, the step certainly is there. Needless to say, I am not a happy camper. For all the C&R business I've done with them, I didn't expect to be lied to.
Caveat emptor, ladies and gentlemen. I'd like to trade this one for another NIB without the problem chamber but finding a dealer who would be willing to do that seems improbable at best.
And to top it off, this is my very first brand new gun. I hope none of my brothers here get burned the same way I did. Learn from my mistakes.
