I have a Tantal kit, in very good condition, only wear is in the finish. Got it from Greentimber last year and never built it. I'd like to do a Saiga AK103 instead so I'm selling it, or trading it for an unconverted 7.62x39 Saiga 16" carbine +.
It comes with the following US made parts: proper Tantal gas piston and muzzle device by Hotbarrel, and a G2 FCG. All you need is a receiver for parts compliance.
Price is $300 shipped.
Edited to add pictures.
Did I mention the numbers matched? Looks like it's a 1991 vintage.
