Ergo AR-15/AR-10 AR Wedge Features The Ergo Grips AR Wedge is designed to take up the small amount of play that naturally exists between the upper and lower receiver on an AR-15 or AR-10 platform rifle. Installation is straightforward: the shooter opens the upper receiver drops the wedge into the rear of the lower behind the takedown pin and then closes the upper back into position. This reduction in receiver movement can contribute to improved shot-to-shot consistency and overall accuracy particularly on rifles with looser-than-ideal receiver tolerances. Because the wedge is intentionally oversized it can be trimmed to fit the exact tolerances of an individual rifle s receiver set. Finished in bright orange the wedge is easy to spot during disassembly and reassembly reducing the chance of losing such a small component during a build or cleaning session. Packaged three to a set this gives AR owners enough material on hand to fit multiple builds or to experiment with trimming for the ideal fit. This is an easy do-it-yourself upgrade that does not require any specialized tools or gunsmithing experience to install correctly. The Ergo Grips AR Wedge is a low-cost high-value addition for anyone looking to personalize and tighten up their AR build.
