Right now Bravo has suspended sale of their lowers.If you need one lower tomorrow which you you recommend.Thanks
I recommend trying again at www.grtactical.com 
As long as the lower is within spec, pick the rollmark you like best and carry on.
I prefer LMT, BCM, Noveske, and DD.
Seconded - I JUST bought a couple from him for a couple of projects - they work great!
When did BCM quit making lowers?
If you can find one the DD is nice with the flared magwell.
Per their website
Due to overwhelming demand of Bravo Company Rifles and Lower Receivers we must suspend taking orders until the back log has been reduced. We will again post order forms for new order submissions early May, 2011. Please feel free to check back here at that time. We will again post the order form link. Sorry for the temporary inconvenience.
As was said above, just order one from Grant
Not taking orders is a far cry from not making lowers anymore.
Cruise Grant’s site for lowers hes got a bunch…I’m partial to Noveske cause of the rollmark 
They didn’t suspend production. They just stopped taking orders until they catch up on the backlog. You can still get one from Grant at G&R if he hasn’t sold off his whole stock.
