I am debating on buying a billet lower because the price is really good ($150).  Should I buy the billet lower for any particular reason over a forged lower?  Any benefits?  I know they are a bit heavier than forged too.  Does this make them more durable than forged?  The ones I am looking at are the ARFcom lowers.

Thanks!

Differences are largely cost, aesthetics and a small strength difference.

The biggest question is what kind of upper:  typically billet:billet will look better; billet:forged may not look right due to dimensional differences between the two.

Billet lowers are nice and some come with features not offered on forged lowers. I bought a NFA billet lower for 79 bucks, it's a blem but you can not find any blems on it. It is really nice. I like the built in trigger guards, it has a threaded bolt catch, and the threaded pin comes with it. The take down detent pin hole is threaded as well and comes with a set screw. It also has the set screw for adjusting play between uppers and lowers. For now I have it mated up to a hardened arms upper. It's forged and I have to say the fit was incredible, extremely close. this is a crap shoot though, some times you get lucky. Anyway, I'm a big fan of billet lowers.

So, even though the ARFcom one is heavily marked down, they can still be had for cheaper?  Maybe I will just get the forged one when I can justify $100 for a lower...

Like raresheg said billets come in more shapes and varieties than forged, but other than that there is no practical difference.

Aero makes an Ambi forged lower that will do everything the Arfcom can, but if the ARF is $150 then I say go for it.

Billet lowers look good on billet uppers, same goes with forged.

Has anyone ever heard of any lower failing?  Not talking about being blown apart by a bad reload or such, but actually failing?

I would think the strength point is moot, however I much prefer the look of some of the nice billet lowers.

Strictly from a metallurgy standpoint, forgings are stronger than purely machined stock. From a civilian AR standpoint, no real difference.

Some Billets are lighter... a full 1/4 pound lighter than a forged set. They can also blend perfectly  Forged:Billet and back.

I prefer billet lowers because they almost always have a built in trigger guard and full ambi controls, which is nice for a lefty. If I end up building another it will be with the BALIOS Lite lower/upper, they are very light weight.

Forged are fine by me.  I have at least 4 diff brands and they all fit perfectly on that many diff uppers.     YMMV
