Geissele Super Duty Stripped Lower Receiver

Geissele's Super Duty stripped lower is the forged 7075-T6 receiver the company uses on its factory Super Duty rifles issued to professional end users. At $175 it is a brand-pedigree pick rather than a bargain: you are paying for Geissele's tolerance control, hard-use reputation, and finish, not for extra features. Controls are standard mil-spec, so plan on a lower parts kit and the selector, mag release, and bolt catch of your choice.

Each lower is precision machined from a 7075-T6 forging and finished with Type III hardcoat anodize in Black or Desert Dirt Color. The fire control pocket is mil-spec (.154" pins) and works with every standard AR-15 trigger, including Geissele's own SSA-E, SD-3G, and SSP triggers. Safe and Fire indicators are marked on both sides.

If you specifically want integrated ambidextrous controls milled into the receiver, look to a billet ambi lower such as the ADM UIC or Griffin Armament Mk2. The Super Duty is a straightforward duty-grade foundation for a right-handed or standard build, and it is the right pick when Geissele's fit and finish matter more than added features.
