The Ruger AR stripped lower receiver in Frazzle camo (Ruger part no. 28508) is the foundation for an AR-pattern build you assemble to your own plan. It arrives stripped, so the trigger group, grip, buffer system and stock are your choices. Ruger machines its AR lowers from forged aluminum to mil-spec dimensions, which keeps parts fitting the way they should. An adjustable tension screw takes the play out between the upper and lower. This one wears a Frazzle camo finish for a build that does not look like every other black rifle.

Key Specifications

• The part is a stripped lower receiver, with no trigger group, grip or stock, so you pick every component.
• The lower is machined from 7075-T6 forged aluminum, a strong alloy used for AR receivers.
• Dimensions are mil-spec, which helps standard AR-pattern parts and uppers fit smoothly.
• An adjustable tension screw is built in to minimize or eliminate play between the upper and lower receivers.
• The finish is Frazzle camo, a camouflage look instead of plain black.

Frequently Asked Questions

Is this a complete lower? No. It is a stripped lower receiver, so the trigger group, pistol grip, buffer tube and stock are added separately.

What does the tension screw do? It is adjustable and is there to reduce or remove play between the upper and lower receivers once they are joined.
