If you’re searching for the best scope for H&R slug gun, you’re likely a dedicated deer hunter or shotgun marksman who values precision, durability, and reliable optics under heavy recoil. The H&R (Harrington & Richardson) slug gun, known for its simplicity and impressive accuracy, demands a scope that can handle the hard kick of 12-gauge slugs while offering crystal-clear visuals at medium ranges.
Over the years, I’ve tested numerous optics on my H&R Ultra Slug Hunter, evaluating them in the field under rain, cold mornings, and dusk hunts. Below, I’ve handpicked the best scopes that provide the ideal mix of ruggedness, optical clarity, and performance at ranges between 50–200 yards — the sweet spot for slug guns.

The ¼ MOA turrets track cleanly with a tactile click. Adjustments are precise and reliable during the “box test.”
Magnification & Parallax:
Its 3–9x range covers most slug gun hunting distances. Parallax is fixed at 150 yards, ideal for typical deer hunting scenarios.

I used a one-piece 20 MOA rail and medium-height Leupold rings for secure mounting. The setup cleared the barrel perfectly.
