I recently acquired an OD green PS90 with factory black ring sight and immediately stamped it. Stamp was approved a few days ago, and I'm trying to remove the barrel, but it is absolutely ****ing seized.
I've removed the blind pin
I've thinned a 15mm wrench
The upper is in a vice
I am turning clockwise
I'm applying my entire body weight to this thing and all it's doing is slipping the upper out of the vice. There is a pretty big mar being formed on the receiver above the flat part of the barrel shroud where it is twisting into the receiver.
Is there loctite or something on this? I know that I have an older model PS90, these were discontinued in like 2012, so my assumption is that maybe fouling has seized up the threads. Does anyone have any suggestions? My only thoughts are a bigger, stronger vice and a breaker bar, but I think if I clamped it any tighter it'd absolutely ruin the finish on the upper.
Did they use a loctite on it as well? Do you think hitting it with my propane torch would help at all?
