best place to buy ar15/m16 rifle?

thanks for the awesome advise :tup:

I’m not 100% sure on the brand of the one we were shooting yesterday, but it got jammed up a couple times. I assume more so the fault of a shitty magazine, opposed to the gun itself?

I definitely want a quality piece, but would like to keep it under 1K if possible. Would I be better off buying used? Never purchased a rifle before so this is new to me
