Yankee Hill Machine YHM-111-300 AR-15 Dust Cover Assembly - .300 BLK Caliber Marked

The Yankee Hill Machine YHM-111-300 is an AR-15 dust cover assembly from YHM's caliber-marked line, specifically engraved for the .300 AAC Blackout chambering. It's a direct drop-in replacement for a mil-spec AR-15 dust cover, designed to fit any standard AR-pattern upper receiver while making the upper's caliber instantly identifiable at a glance.

Built for regular service, the cover is machined from aluminum and finished in a Mil-Spec hard anodized matte black for corrosion resistance in the field. It's a sensible upgrade for shooters who run a multi-caliber AR and want each upper clearly badged, or for anyone re-configuring a standard upper to .300 BLK.

The assembly ships complete with everything needed for install: the caliber-marked dust cover, rod, retaining clip, and spring. Like the rest of YHM's accessory line, the YHM-111-300 is Made in USA to Yankee Hill Machine's quality standards.
