Ranier Arms has Noveske cosmetic blem stripped lowers right now for $150.00.

Stag Arms complete uppers with BUIS for $535.00

chrome lined barrel with M4 handguards, options include bolt carrier group and charging handle & flip up rear sight.

or...

Stag A-4 upper with Picatinny gas block for $465.00

Let's see 465 and 150 will put you at 615 but you'll still need a parts kit for the lower and a stock.

Rainier is good to do business with too.
