First off, kiddo...you need a Class 3 license for an Assault Rifle.
Assault rifles are full-auto and regulated heavily in the US.
What you are REALLY describing in the SAIGA is a semi-automatic Para-military rifle. Also known as an SUR (Semi-auto Utility Rifle). Learn the difference.
Let not the words "Assault Rifle" pass your lips unless you are speaking of a fully automatic weapon.
Let not the words Old-Timer pass your lips unless you wish to find out why old people survive long enough to become grouchy.
