As everyone has said, shoot your AR. Do drills with it. Then figure out what bugs you. Trigger? Charging handle? Pistol grip angle? Sights? LOP? Then fix those issues as you need.
You say it’s a NEA receiver (lower?) There is not much love for NEAs as a rule. Any thing and parts you add to your rifle may be cost that you will never recoup back. You can easily turn a NEA into a $2000+ rifle but when it comes time to sell, you will never get close to getting your money back as a complete rifle.
Since you want a C8 clone and you basically want enough parts to build a spare rifle when it’s all done. Why not just wait, save your money and source a Colt Diemarco when you’re ready? Shoot the NEA in the meantime and learn on it.
This 1000%
I’ve a big hate on for NEA, but if it’s what you have, just shoot it as is as cheap rifles aren’t worth upgrading because it’ll always just be a cheap rifle. Since it is an NEA, shoot the cheapest, dirtiest amp you can find (the goal is cost savings) so you can shoot the NEA all the while saving for the C8 you really want. Slowly turning an NEA into a C8 is just going to leave you with a mismatched frankenbuild, save your coin, and eventually buy a C8 complete upper receiver, and then sell the NEA upper to fund your Colt Canada lower.
NEA Haters, please...
I don't have much to add but this, there's nothing wrong with an NEA Rifle.
It makes more sense to use the money to buy good optics and ammo, shoot the hell out of the NEA until it breaks and then buy a complete new rifle.
Stupid question:
If I have my AR set up with a 10.5" upper, and decide that the next day I want to use my 16" upper, do I have to call the CFC to update the registration?
What if I have an stripped lower and then buy the rest of the lower parts and an upper to put on it, does that require updating the registration?
Legally, yes.
