We have ONE of each of these builders kits in stock. They include the stripped M4E1 lower receiver, the assembled M4E1 upper receiver, and the 15" Atlas R-ONE MLOK handguard. These are brand new display models. The gray has some scuffs and nicks in the Cerakote. With the anodized green set, all three pieces are a slightly different shade (common with anodized parts). Either way, you save about $150 over normal pricing for these parts. Call or text to swing by and check them out.
