First and foremost, I'm a gunsmith (not gomsmif) by trade and generally know what I'm doing. Secondly, I use good jigging to assemble items correctly, so hopefully that gives you an idea of perspective here.
Ordered two of these, directly from PA, brand new this past week and today I assembled a rifle using one and a YHM gas block, jigged it up and pushed the roll pin in with my knipex, then put the gas block on my rifle. First glance and I notice the gas tube is bent at least 1" off center, so I'm alarmed and wondering if I did anything somehow or if it was like that when I received it because I've never seen a gas tube that was so bent from the box. Upon further inspection and prodding, I discovered that neither gas tubes are tempered or treated and so soft that you can bend them between two fingers on one hand.
I assume this was a fault of their OEM, but either way the batch they came from is definitely bad. Never in my years have I seen a gas tube this poorly made, and I've seen a few pretty terrible ones.
I do have pictures
Pictured was done with extreme ease, hahaha.
