For most purposes the semiauto will be far better--

A full auto just sprays shots unless you practice alot in the 3round burst mode.

Do I think there is a need for civilians to have semi auto's? Absolutely!!! Autos?? Fun but generally just a waste of ammo.

The AK knock offs are cheaper but not "politically correct" and tend to ID you as a bad guy in the states.They can get you shot easier by the police too!!No protective vest usually used will protect against them.Police tend to react quickly if they are seen.

IMHO-Best bang for the buck is the Ruger "ranch" gun in 7.62x39-
A used ruger is relatively cheap,requires little maintenance and can be carried year round in a hot truck. They can be also be accuratized somewhat.AR-15's are great if kept clean and oiled but are pricey($1000-1500)and foul up with dirt/crud if ignored.If money is no problem the AR-15 with the 6.8mm caliber upper is the ticket and a great gun being extremely accurate at distance as well.

Hope I never have to use a firearm on a perp but better to be prepared.The rifle in your truck is also a great backup for the handgun you carry as well.

It's not about laws keeping arms from all civilians, its about innocents having the ability to protect self and family.A semiauto works just fine and I always end up using it several times a year at home on vermin/coyotes and at the hunting club--
A good truck rifle is great to have handy when a rifle is needed.At home they always seem harder to access safely with children about.Thats as it should be.Safety first!!
