LPKs are a biatch to find right now, as we all know. i called, they said the quantity the website shows in stock is whats in stock… and it says 100 in stock. they said the LPKs are “various” manufacturers, so who knows what you’ll get. I ordered a few.

Nice find. And, as you say, “who knows what you’ll get”.
Well so much for that. Saw this thread sitting around bored at the relatives, ordered two showing 70ish available, got email this morning saying order cancelled due to volume of sale.
He appears to have shut down all online ordering.
I was getting ready to order a 9mm upper and the shopping cart feature dissapeared in the middle of the order. 
yep… the LPKs he told me to go online and order a week ago just got kicked back out. sounds like more than just “volume of orders” to me. but i only speculate.
sorry for the bum lead, gentlemen.
