There is some over correction on occasion.
However firearms, the law, and politics are very interwoven.
Because of that the terminology of components can be more important than with other objects.
The terms used for items change thier political fate as well. "Assault weapon" is a great example.
The difference between a "muzzle break" and a "flash supressor" can be the difference between a felony or a harmless item in some states.
They are both similar pieces of metal screwed on the end of the muzzle.
Soon as ANY topic comes up involving black rifles
As I was saying above politics and the law have made such items less than casual. Those are some of the most legislated against firearm types. So terminology is most important concerning items with more legislation that refers to thier parts.
If you call a muzzle break a flash suppressor in CA, it can mean the difference between a felony and a legaly installed item.
Lets take a mini 14 because they are a common rifle that is not an "assault weapon" stock in CA, but easily become one if you add one wrong feature.
This is a legal "muzzle break":
These are "flash hiders" and turn the rifle into an illegal "assault weapon" and make you a felon:
Once again in case you missed that.
Felony:
Non-Felony:
This is legal because it takes a "clip":
But this is a felony because it takes a "magazine" becoming an "assault weapon" under the law:
Thank your politicians. The words are very important. The words when talking about "black rifles" as you call them are even more important.
