A Romanian-made guns (hi-cap, dimples, chrome-lined, CHF bbl, threaded muzzle, and Romy FCG) marked as "Draco C" have the underfolder trunnion built-in, the "non C" does not. The Draco Mini - don't know. You'll know a mini when you see it. Supposedly no more imported of ANY Draco.
Fun guns! My Dragon -
ETA: the new Yugo PAP pistol in 7.62x39 has been trickling in and folks have been snagging them up since the Dracos have dried up. Things like canted gas/trunnions are rumored to have been seen, whatever - good Yugo build quality but typical non-chromed bbl.
They have a slant to the rear of the recvr which creates a challenge for adding any type of stock given the the S/N is right near where an U/F trunnion would fit.
Google "Yugo M92 pistol"; someone did a review of one and posted it on absolutely every single AK forum in the known world. (He may work for Zastava or Arsenal as he did the same for an Arsenal AK he bought. Mighty proud of his purchases unless he got some deal to shill product... )
