The M&P15 MOE SL Mid combines the mid-length gas system with Magpul's Slim Line furniture package on S&W's standard M&P15 platform. The SL handguard has a reduced outer diameter versus standard MOE, improving ergonomics for shooters who prefer a thinner grip on the handguard. Mid-length gas provides the recoil advantage on the 16-inch barrel. A refinement of the successful MOE Mid lineup.
