the JNG-90 fires 7.62x51mm NATO rounds, everything you are saying is not only stupid but also totally irrelevant
in fact, its standard flash hider is outlandishly huge
I'm not going to know every make of rifle by visual. Hell, a lot of the weapons on here i don't recognize. Not to mention that weapons come in
multiple calibers. My initial point with all this aside is that its completely plausible for a rifle like that to be chambered for .22 and that barrels that small exist. Then we started a conversation on how deadly a .22 actually is.
So everything you've been saying is irrelevant to the point I was initially making. Good job.
