I was gonna comment about their hypocrisy whining like a child and trying to reaffirm their own manhood.
I’d also like to point out that this paid instigator is handing out illegal advice in other threads
And in reference to serial numbers;
Then further illegal advice;
As well as some amazing online gunsmithing advice;
I’m not a gunsmith, so maybe, just maybe that might work on a FTE situation, but a new manufacturer firearm should not need such brutish and warranty voiding kind of modification.
So, to recap, promoting carrying potentially stolen firearms with defaced serial numbers which was, and in some cases can still be a felony, and encouraging intentionally damaging otherwise new firearms.
Doesn’t sound like someone promoting proper lawful firearms ownership in the United States of America to me.
