Ergo Ar-wedge 3pk

The Ergo AR-Wedge 3pk is a precision fit-and-function accessory designed to eliminate vertical play between the upper and lower receiver of your AR-15 platform rifle. Whether you're a law enforcement armorer managing a duty rifle fleet or a serious shooter optimizing accuracy and reliability, receiver wobble directly impacts zero stability and shot-to-shot consistency. This three-pack allows you to outfit multiple rifles or maintain spares—a practical solution that costs pennies per rifle but delivers measurable improvements in handling and repeatability.

Each wedge is engineered to fit into the gap between upper and lower receivers, taking up tolerance stack that accumulates from manufacturing. The design is intentionally oversized so users can trim to their specific rifle's geometry—a feature that reflects real-world armorer feedback, since no two AR receivers have identical tolerances. The lightweight polymer or composite construction ensures zero shift in sight picture while resisting temperature and humidity changes common in field conditions. Installation is tool-free and reversible, making these wedges compatible with any AR-15 variant without permanent modification.

Law enforcement duty rifles, military training platforms, and precision shooters benefit most from tightening receiver-to-receiver lockup. A single loose receiver joint can introduce 0.5 to 2 minutes of angle of unintended vertical movement under recoil—enough to miss target vitals at distance or fail qualification standards. The Ergo AR-Wedge 3pk is compatible with all AR-15 lower receivers and standard mil-spec uppers, including flat-top, carry-handle, and modular upper designs. Simply position the wedge, trim as needed with a utility knife, and test fit before final installation. Compact enough to carry spare wedges in a maintenance kit, these are essential inventory for armories and serious competitors.
