A capable holdover-reticle scope for muzzleloaders at the price, but the illuminated-dot version and one report of degrading accuracy are worth weighing before buying.

Overview
A hunting riflescope built around an engraved ballistic reticle with aiming references from 75 to 275 yards, plus lateral hash marks for windage and lead on moving targets. The 1 inch tube is nitrogen purged and rated waterproof, fogproof and shockproof.
The idea here is holdover without math: the reticle itself marks yardage points so a hunter can aim and fire rather than dial turrets mid-hunt. Several reviewers mounted it on CVA muzzleloaders on the maker's own recommendation and reported it held zero well. Two reviewers had real problems, one with a dim, off-center illuminated dot and a dead battery out of the box, another whose accuracy degraded over repeated cleanings until the scope wouldn't group at all.

- 1/4 MOA finger-adjustable turrets
- Nitrogen-purged waterproof, fogproof, shockproof tube
Who it's for
This scope suits muzzleloader and rimfire hunters who'd rather aim off reticle marks than dial turrets for range. It's a weaker fit if you specifically want a bright, reliably centered illuminated dot, since one reviewer found that feature lacking.
What buyers say
From Amazon customer reviews.
Most reviewers who mounted this on CVA muzzleloaders were happy with brightness, clarity and holding zero, with several calling it a strong value against pricier glass. The complaints centered on the illuminated-dot model, one buyer got a dim, off-center dot and a dead battery, and on a single report of a scope that grouped progressively worse after repeated cleaning until it wouldn't hit paper reliably.
Strengths and trade-offs
Drawn from this product's published specifications.
- Illuminated dot version reported dim, off-center, and arrived with a dead battery on one unit
- Zoom ring reported hard to turn despite marketing claims
- One reviewer's accuracy degraded significantly after repeated cleaning and use
