I'd jump on it either way.
95% of the STG kits that came in had less than 50% wear, with a large majority of them being virtually unused. I ordered one back in 99, and have it assembled into a Carbine with 16.25" barrel, and it functions well. (Gear logo Imbel receiver)
The STG in the picture I posted is DSA's "Parts gun", and from his description, this is most likely what his dealer has.
I'd venture to say that the other rifle he described for $1200.00 is a SA58, DSA's US new production weapon.
Either a homebuilt one or the DSA parts gun would be a average value if purchased inthe $750-850.00 range, as this is what they'd bring anywhere else.
I'd jump on it, FAL parts kits are drying up, and prices are going up..... Only a matter of time before they all are near $1000.00 for one....
