OK- its time I stepped up and moved into a billet lower, not that I will find what I am looking for!
So how about Noveske, or Mega. Mega has like three different model numbers?
I am on the list for what ever one comes in first at Rainier Arms.
So for those that have one or the other- what do you suggest.
My Spikes are fine, I just want a billet for my next build. also what about the various
billet uppers- yes or no? And why.
Thanks all
I dunno about the ones you listed, but the Black Rain Ordnance billet set I have is freakin sweet

They are not on your list but I would go with Larue Tactical.
I don't think Noveske makes a billet lower receiver. I've built on Spikes, Mega, and Seekins.. All three were flawless and have performed as expected.
Spikes lower-
Mega Lower-
Seekins-

I'll look at Spikes, Black Rain and Larue also. Thanks
