All of these are too heavy for a 9mm carbine. The TNW is 5.5 lbs. ambi eject, uses Glock mags and only requires a barrel/bolt head exchange for a different cartridge.
I suppose if you have to have a 9mm AR then you should have one but there are more versatile options out there.
No stake in the fight, I don't own either one.
Not really the point I was making. The poster I quoted stated that he didn't like his AR pattern cause it was heavier than either his PCC or Camp Carbine......which IAW spec sheets is a little "off".
