I would NEVER purchase an AR-15. Ever.

Mainly because I have a 7.62 Vepr with a 27” barrel

Sorry if that’s the case....but you succeeded too well.

That gun would drop the green haired fairies real quick. 308 boy!

I know a dude who may want to part with his if you want me to ask. No it’s not stolen, he is a former member of the Air Force honorably discharged.

Please do

Unless you plan on doing any actual hunting with it (deer, hog, etc.) get a .22M4 platform. Ammo is cheaper (especially in bulk), it will still kill if you need it to, and it's a lot cheaper to shoot.

Of course you probably already know this, but if you do get an AR15, only buy one stamped 5.56, do not buy a rifle stamped .223.

.223 Wylde is fine and generally considered more accurate.

So if you are buying for a cc weapon who is going 9mm and who is going .40

Which brand, model, why?

The 9mm guns, mostly, seem easier for the wife to use.
