Jig alone is worth $250 if you look up the lower you’ll see how pricey they are.
Will come with milling jig to complete the lower. Since the lower isn’t milled there is no serial number this is what’s referred to as a GHOST
To complete the rifle you’ll need a lower parts kit, a stock, and you’ll have to mill the lower and you’re set. I can throw in an AERO precision nickel BCG for an extra $150
Might consider trades for 9mm handgun or gold jewelry
