I've posted before that I have one with a folding brace. They're excellent little shooters. On the heavyish side but they're accurate for what they are. The stock iron sights suck ass though, I've replaced mine with the Khyber Customs set and I also have a Stormwerkz picatinny rail on my dust cover near the hinge like the Serbs do on their military models. It's quite strong and holds a zero perfectly.
Mine takes the 5.56 Serb AK mags though, not the AR mag adapter. I've heard hit or miss things about the mag adapters. Steel 5.56 mags usually go for $40 a pop. CAI used to sell them for around $16 when they were still the importer but I guess that doesn't matter anymore.
Overall, the Zastava M85 or full length M90 are probably the best 5.56 AKs on the market next to S-AM5s. They have the desirable bulged trunnions and are absolute tanks and fairly accurate despite being AK platform weapons. I'd take them over Beryls or SLR 106s any day despite the mag commonality issues.
