What is interesting is this is the 3rd receiver I have worked with. Its the only one (very small sample) that reacted that way.

Worth noting for someone new to this.

the others were clamped to the NSS recommend 25 ft lbs on the cap screw, this one was lighter and almost none and threads were affected.


I like the action wrench as I think it works better and have not been disappointed. I think its easier overall. Easily avoided the issue and I like the hold setup better. Agreed others feel differently.

I don't use a torque wrench to loosen, breaker bar if needed. I don't like smacking the nut wrench with hammers as it beast up the nut wrench. I know it works and sometimes a sharp hit is better than slow strain, still prefer lesser force and or toque to smacking.

The OEM barrel came out ok so agreed the thread differences can be enough to cause issues. Just surprised at how little pressure.
