The Midwest Industries Combat Rail HD M-LOK Handguard in 13.5″ (Midwest Industries part no. MI-CRMHD-13.5) extends the Combat Rail HD line to a longer length suited for mid-length and rifle-length gas systems where extra rail real estate matters. Midwest Industries reinforces the Combat Rail HD series at the M-LOK slots for durability beyond its standard handguard offerings, standing up to mounted lights, foregrips, and the bumps and impacts that come with hard training or field use. At 13.5″, this handguard gives shooters more room to mount multiple accessories, run a longer sight radius with back-up irons, or simply extend hand placement further forward for a more stable shooting platform on a designated marksman or precision-oriented build. The free-float design isolates the barrel from handguard pressure for consistent accuracy.
