Yankee Hill Machine Co Gas Block Riser, Mount, Black, Picatinny YHM-230
Yankee Hill Machine
The Yankee Hill Machine Mini Riser is a compact 0.5-inch picatinny rail riser built to elevate optics, sights, lights, and other accessories on your AR-15 platform rifle. If you're running a lower-third co-witness setup and need to clear iron sights, a red dot that works better at eye level, or a light that sits higher on the handguard, this little block does the job without bulk or weight penalty. It's the kind of accessory that takes five minutes to install and makes a real difference in how your rifle handles and shoots.
Yankee Hill Machine engineered this riser from aircraft-grade aluminum and hardcoat anodized it to a durable matte black finish that meets or exceeds military specifications. The fastener design—a larger screw for increased clamping force—locks your gear in place without slipping or shifting. That's especially important for duty or hunting optics where zero shift isn't an option.
At 1.25 inches long and 0.5 inches tall, the Mini Riser adds minimal profile while providing genuine utility. It accepts any standard picatinny-rail accessory, so you can stack your existing gear on top without hunting for adapters or compatibility workarounds. Whether you're fine-tuning sight height for precision shooting, mounting a light on the upper receiver, or experimenting with different optic positions, this riser gives you the flexibility to dial in your setup exactly how you want it.
