It’s the whole reason I went out and bought one from PSA still cheaper than AO even with shipping. Already threw a Zhukov stock and grip on mine. Hunted down a legit UTG Saiga quad rail and a GK02 replica from Carolina shooter supply.
So the deal isn't great at all, but I personally have one of those shotguns and it's fantastic, closest thing to a real Saiga to the point that any Saiga parts that are not the gas block fit.
