sup, stonksbrah!
i truly don't mean this to sound elitist/snobby/closed-minded, but seriously... if you have any desire to have ar15s/etc, gtfo of ny. the gun laws are atrocious.
and then get a pws.
https://www.primaryweapons.com/ because ar15s are all at inflated prices, anyway.
but you could get a ~typical ar15 (ie: palmetto, anderson, whatever) for ~$800 (and probably in the 650 range if you look for deals*), but you'd then need to have it neutered before you could pick it up if it's not already.
i'd recommend keeping an eye on/signing up for emails from aimsurplus, palmetto, and primary arms (especially for optics/accessories)

https://aimsurplus.com/radical-firearms-223-5-56x45-socom-b5-m-lok-rifle/ - this was in their 1/8 email and was $659.
for low/mid tier ar15s, honestly, as long as their mil-spec, they're pretty much all the same now, configurations aside.
and fuck. i always forget that this subforum exists.
