I think the lowers are all pretty basic. I'm sure you could customize them, but they're like $50 out of the box. Talk to Biggerhammer about them. The reason to get them now is because they're the part with the serial number. Once you build your rifle, that's the identifier. When they start telling us to register our ARs, that'll be it. I believe with I-594, you'd probably have to go through an FFL to purchase on in WA. In OR or ID you can just go pick one up.

I guess Biggerhammer had better answer those questions. I know you can do different coats, etchings, etc. But, I think you can buy a lower without a background check. It might have to be from an FFL, but I don't know why it would. I bet you could find a couple in classifieds. There's some loophole regarding un assembled parts and also, there used to be laws related to the "assault weapons ban" which no longer apply. Ask BH, send him a PM. He helped me build a heck of a predator gun.

The lower with the serial number has had to have a background check, even before 594.  Uppers can be bought and sold with no check but lowers are registered to you. 

As far as quality I will leave that up to those with more knowledge.

It's the same as buying a firearm. You need to get the background check. Even before 594 you still needed to go through the background check if going through a dealer. Also if ordering online it needs to be shipped to a FFL.

Bearhunter beat me to it.

Thanks for correcting me.

Lowers are lowers with the exception of Persenal preference. A $50.00 Anderson will perform the same as any more costly billet. Along with the quality billet lowers come the extras (Ambi bolt catches, tension screws etc). Beauty is in the eye of the beholder.  The proof on paper and performance when it comes to accuracy is the barrel. The rest is all mass produced mil-spec stuff, sure there are some exceptions, but you would be surprised how many different company names are stamped on AR parts coming off the same machines.

Persenaly I would put the extra $$$ into a quality billet upper receiver before I would a lower. Not a must but it doesn't hurt to have the longer and heavier barrels seated in a stout receiver in my opinion. As for a standard weight or carbine barrel any upper will do. They are all modular and fairly simple once you have done a complete hands on build yourself.

As for the lower it is best to pick one up at a local shop, I know our local shops sell Anderson lowers for $50.00 and the paperwork is included. AIM Surplus carries Anderson lowers for $40.00 bucks usually free shipping but on the other hand our local FFL's charge $40.00 a lower to receiver them and do the transfer.

Mega does quality forged and billet stuff. Griz Precision a board sponsor has some good prices on their own billet lowers.

No problem. I've bought a few...

I'm an expert. I've bought one.

The way i understand it is there really is only 1 lower that all other manufactures use (unless of course its billet).The logos and such are just put on when ordered.

there is not just one manufacturer thats makes all lowers, but there are a few companies that provide lowers to many of the manufacturers. i have an Anderson as well as an Aero Precision lower. they both work like they should and haven't had any fitment problems swapping out components.

Most tend to blame lowers for fit issues , more often than not its the lowers parts kit parts being out of spec or coated to heavily. This is seen more often when fitting a "Selector switch" when the coating is to heavy on the selector and its a tight fit. Nothing a few minutes and some Emery cloth won't smooth up on the selector. I've seen the results of guys going after the lower will a dremel tool to remedy the issue, not the thing to do.

Always start with the cheapest part.
