DNZ Picatinny Scope Riser Mount for Rails — 1/2" Rise, 5.25" Black, repeatable zero

This precision-machined scope riser from DNZ fits Picatinny rails and positions your optic half an inch higher without altering the firearm's base length dramatically. Built for repeatable mounting and a clean, low-profile silhouette, the YHM-227A is useful when a higher cheek weld or additional clearance for backup sights or barrel accessories is needed. The black finish blends with most modern platforms while the compact 5 1/4" footprint keeps weight and bulk minimal.

How does this riser change my shooting setup?

The 1/2" rise adjusts your sightline so your eye aligns with the optic more naturally when using taller stocks, thicker mounts, or added accessories. It preserves zero when installed on a Picatinny rail and maintains a solid interface between optic and rail for consistent return-to-zero performance.

• Raises optic by 0.5" for better cheek weld and sight picture.
• 5.25" length spans typical optic footprints for stability.
• Picatinny interface ensures repeatable mounting and secure fit.
• Black finish resists glare and coordinates with common firearm colors.

What rifles and optics are compatible with the YHM-227A?

This riser is intended for firearms that use a Picatinny (MIL-STD-1913) rail and for optics with standard footprint and ring spacing that fit within the 5 1/4" mount length. It’s ideal for red dots, low-power variable optics, and some compact scopes when extra height or clearance is required.

• Fits Picatinny rails on AR-style rifles, shotguns, and precision platforms.
• Works with most red dot reflex sights and compact scopes within its length.
• Provides clearance for backup iron sights or muzzle accessories.
• Compatible with optics that accept single-piece riser spacing within 5.25".

How durable and repeatable is the mount under field use?

Manufactured to the tolerances expected from Yankee Hill Machine Co. parts, the DNZ YHM-227A offers reliable clamping and alignment when torqued to recommended values. The robust construction and finished surfaces reduce the risk of movement under recoil and maintain consistent point-of-impact when remounted.

• Precision-machined body for stable engagement with Picatinny slots.
• Black protective finish decreases wear and glare during use.
• Engineered for repeatable zero when secured correctly.
• Compact footprint minimizes added weight and offset torque.

Who is this for: Shooters who need modest elevation for their optics without committing to taller, heavier mounting systems will find the DNZ Yankee Hill Machine Co Scope Riser Mount YHM-227A useful. It suits AR-platform users adjusting cheek weld, hunters adding clearance for accessories, and tactical shooters who want a low-profile, repeatable riser that integrates cleanly with Picatinny rails.
