A Simple Upgrade for Serious Reliability
The Sprinco Mil-Spec Black Extractor Insert and Viton O-Ring combo is a proven solution for enhancing extractor tension and ensuring consistent case extraction in your AR-15 or M4 platform. The black insert reinforces extractor tension within mil-spec standards, while the Viton O-ring adds additional grip on the case rim, which is especially useful in rifles with shorter gas systems or increased bolt speed. This 3-pack gives you enough for multiple builds or spare parts kits, and it pairs perfectly with Sprinco’s extractor springs for a full reliability upgrade.
