My first AR was a Norinco CQ-A, I still have it.
By the time I installed a free floating handguard, low profile gas block, Magpul furniture, etc I was over $1,000 back in 2011.
I also spent quite a bit on tooling also.
Even though the Norinco shoots fine I think you will get a better long term value for your money out of a Stag, Daniel Defense, or Wyndham Weaponry.
What you must figure out first is the type of shooting you want to do to determine the barrel length first and the overalll style next.
A barrel shorter than 16" overall cannot be brought south of the border.
To the ATF a 14.5" barrel with a pinned and welded flash hider with an overall length longer than 16.0" is considered legal.
As for overall style do you want a carry handle and post style front sight with traditional handguard?
Do you want a free floating handguard with a continuous rail on top you can mount an optic and backup sights?
These days you can chooses a quad rail which is fatter and heavier or More modern styles styles such as Keymod or MLOC which are thinner and lighter.
Do you want a red dot aimpoint or EOtech or a magnified 1-4 or 4x16 scope?
I would speak to people you see at the range with AR's and ask if you can hold them, most people will offer you a chance to shoot them.
Best of luck and once you buy one you will never have enough of them.
