From what I saw the OP's replacement stock is about the only part I'd trust from them. I was checking out their products today and they mostly look like they have high school vocational school freshmen welding them up for them.
Here is a perfect example. It's one of their "concept guns". They weld EVERYTHING! Look at the crap welds partially ground smooth where they, for some unknown reason, welded the lower handguard to the receiver, and even worse, they absolutely butchered the weld job on the rear sight. I don't usually like bashing businesses, but these people have no business working on a Red Ryder BB gun, let along an AK!
They even weld round stock from the front sight to the gas tube and from the lower handguard, which is welded to the receiver, to the MUZZLE BRAKE! This place is a joke.
And their "Concept Rifles" have their gas tubes wrapped with paracord? Just what I want on a part that can get hot enough to set wood on fire. I know, probably not on semi but I've had wood smoking on a registered select fire AK after just 5 or 6 mags.
And their scout mount is just amazing. Putting .22 rimfire scope rings on the gas tube, upside down, then wrapping it with paracord and welding the tube to the rear sight block is just genius.
Just my opinion, but someone who can't been take the time to stamp the "USA" markings somewhat neatly on their safety levers sends up red flags to me.
I know a lot of people have used their AMD stock adapters with good results. But from what I saw on their site I'm more than a little cautious about their other products.
That said, I bought some 5/16" round stock last night to weld on my own stock adapter.
