Posted: 11/21/2013 11:38:59 AM EDT

I'm building a car-15 Vietnam copy it's complete to the point of choosing a barrel , and I live in Illinois. So should I go with a 11.5 inch with 5.5 flash hider or keep the ballistics of a 16 inch barrel with a fake slip over 5.5 flash hider any photos would be nice Thanks for your time !
