Yankee Hill Machine Extended Picatinny-Style Riser Mount AR-15 Flat-Top Matte

The Yankee Hill Machine Extended Picatinny-Style Riser Mount for AR-15 Flat-Top lets you stack optics and accessories where space is tight or where you need a higher sight line. This 6" rail extension mounts directly to any Picatinny rail on your AR-15, adding a full secondary mounting surface while elevating it 1/2" for improved cheek weld, better co-witness with irons, or simply clearing your handguard. Built from aircraft-grade aluminum and hardcoated to military specifications, it handles the recoil and abuse that come with duty, hunting, and range work without flex or shift.

Whether you're running a reflex sight over an ACOG, stacking magnifiers on a red dot, or mounting backup optics and lights in a crowded rail space, this riser gives you the real estate you need. The matte finish resists glare and blends with most AR furniture. It's a no-fuss way to optimize your sight picture without replacing your entire upper receiver or handguard.

Yankee Hill Machine is known for solid, no-nonsense AR components, and this riser is built to stay put. If your AR-15 flat-top already wears a Picatinny rail, this extension bolts on in seconds and doesn't require gunsmithing or special tools.
