So you want to buy an AR-15 - FAQs

Lets bump this to the top. Last post was more then 3 years ago. Seemingly lots of people that don't usually buy guns and ammo, are doing that now, with the Corona Virus, and the uncertainty in the upcoming election.
Why are people buying AR's of all types that have never shot a gun in their life? Proper training and a pistol of the persons liking, i.e. comfortable with, will protect your household better then carrying a clumsy rifle trying to run around inside your house.
Design wise, AR's are for, around, 100 yards and out, way out for AR10 variants. Most houses the yard isn't that big, shooting these guns in the house will endanger all your neighbors as the bullet flies through the next couple of houses. Proper ammo can negate most of this, but still, why is EVERYTHING being bought up by people that will probably never shoot it?

Rant over, obligatory pictures.

Loaded 25 round .308, at 9 pounds, fuck yeah.

 

Um, no.

Or pick your own source.

Pretty every round is gonna have some overpenetration (unless you get frangibles, or go small in your pellet sizes).

It's a matter of ergonomics, and IMO in a stress situation a modern short carbine is one of the best handling weapons out there. Which means you'll have better aim with it as well.

YMMV.
