No idea if the original poster is still around but this was an entertaining thread.
As someone that actually owns and USES one I can say it's decent. My bolt looks new and it's probably because of the s7. PSA AK I got to handle at my lgs. It did seem smooth to cock however have you seen a PSA bolt after 2-3 k rounds? The one robski tested looked beat to hell. Tail was deformed badly imho though robski said it looked ok. I did not tear it down I have no desire that bolt said it all.
Also no side rail like the VSKA. The VSKA dummy rivets that seem to be where the rail would be mounted are not the same size as an aftermarket rail I bought from Amazon.
i recently put the hogue ghillie green furniture on and that gave me a hand guard rail to mount a red dot. Honestly both furniture looks good to me. The original is tight minimalist and very slick looking. The hogue adds weight but offers better grip and a rail option. The hand gaurd was the standard Chinese/Russian akm. So I assume any Chinese/Russian furniture fits.
its not a real AK some say. They are full of it. It's very real. it looks different the sight block is also the gas block. That is the look of an AK pistol baby! The trooper is small compact and looks good to me. Everyone has seen a standard full size AK the wood furniture separate gas block and cleaning rod that you will never use that gets in the way. Awesome. One AK that looks exactly like all others how boring. One can say if it's not a Russian saiga then it's not a real AK too. Polish, wasr, Chinese they all are not real aks because they are not Russian. One COULD say that.
i can't speak to internal parts compatibility I won't worry about it from what I see as long as the rear bolt mating surface and the receiver stay in shape the rifle should be fine.
i will invest in a field gauge at some point. Damn expensive stupid metal thing should cost 10 bucks not 50. Till then if it blows up no prob it's an AK baby! The thing will blow dust cover will scare me and I will be fine. Like an AR that blows well literally up and splits in 2. It's like these things were designed that if they did blow up they would not harm the shooter. Go figure.
