Lower Receivers

The essence of the AR rifle or pistol and the only part that is serialized, this part is where many people start when building a new AR-15. Our custom lower receivers are crafted from superior 7075-T6 aircraft grade aluminum. These durable, high quality, mil spec lowers are either forged or billet manufactured allowing for more options depending on your preference. We combine the lower receiver in a stabilizer brace kit with a stock, a buffer tube, and a lower parts kit. We also combo it in our Custom Arms builder set with our 3rd Gen Tactical 'Humboldt’ upper receiver, and a 15” M-Lok handguard for a flawless fit and increased value. Where available we offer the option of assembling these build kits prior to shipping for further convenience.

Important FFL Requirements: These items are FFL restricted shipping products. You must arrange shipment of these products to a qualified FFL dealer.
