Have enjoyed them here, so far. Got a PSAK from them. It looks and feels immaculate, price was good, and the shipping was just a tad slow but went without hiccups. Then again, I got it between rushes.
Had it for a good long while now, and between working night shifts and the pandemic, I have yet to actually shoot the thing.
Doubt it's a problem with their ARs, but the AK is tight in places. They modeled it after a respected manufacturer and then tried to build it to American standards. AKs like being a little loose here and there. This one feels at least as snug and solid as my Russian Saiga did, which is good, and Pmags fit perfectly, which is good, but my steel mags (all the same origin) needed inserted and removed until they scuffed the finish off at the contacts, and a couple Chinese-made 5-rounders won't fit at all.
Maybe not a huge problem, and not unusual with AKs, but still.
