Delivers sharper zoomed-in image quality than some pricier digital scopes reviewers compared it against, with a stadiametric rangefinder built in. Budget for spare rechargeable batteries and a slow warranty process if something fails.

Overview
A digital night vision riflescope with a 4K CMOS sensor and 1280x720 FLCOS display, rated to identify objects out to 300 yards. It records AVI video in 1080p or 4K and pairs a first focal-plane reticle with 8x digital zoom for daytime or IR-illuminated night use.
Unlike a traditional optical scope, you are viewing a screen fed by the front mounted camera, a distinction more than one buyer had to relearn after delivery. Multiple owners who had used other digital night vision brands singled out image clarity at zoom, saying it held detail where competitors like ATN pixelate.
- 4K CMOS sensor, 1280x720 FLCOS screen
- Records AVI video in 1080p or 4K
- First focal-plane reticle, 8x digital zoom
- Rated to .308 caliber, shockproof to 3 ft
Who it's for
Suits hunters and shooters mounting a scope for both daylight and IR-illuminated night use on rifles up to .308 caliber. Less suited to anyone expecting warranty support to move fast if a unit needs repair.
What buyers say
From Amazon customer reviews.
Owners praised the zoomed-in clarity against other digital scopes, easy bench zeroing in a few shots, and the balance on the rifle compared to bulkier competitors. The sore point was Sightmark's own warranty service: one buyer described repeated unanswered calls and voicemails after a lens defect appeared just past Amazon's return window, and another noted the IR illuminator needs backup batteries to last a full night.
Strengths and trade-offs
Drawn from this product's published specifications.
- Sharp zoomed image versus other digital scopes
- Stadiametric rangefinder built in
- Lightweight, does not unbalance the rifle
- Works in daylight or with IR at night
- Slow, hard to reach warranty service
- IR illuminator batteries drain over a night
- Digital display, not a true optical sightline
Performance notes
The scope displays a live feed from its 4K CMOS sensor on a 1280x720 screen rather than offering a true optical sightline, and it includes stadiametric rangefinding, a distance estimation method that predates laser rangefinders and does not emit a detectable IR signal. Reviewers zeroed it in from a bench in as few as three shots. The built-in IR illuminator runs on CR123 batteries separate from the main battery pack, so night-long sessions need spares on hand.
