Glass Clarity & Reticle:
The glass clarity punches above its class with decent contrast and brightness. The Truplex reticle is simple yet effective, perfect for quick target acquisition on small targets.
Eye Relief & Eye Box:
Generous eye relief of 3.75 inches makes it forgiving for rapid shooting sessions.

I mounted it on my M&P 15-22 using standard Weaver rings, fired over 500 rounds, and it held zero perfectly — no internal rattle or shift.

FAQs
1. Do I need a rimfire-specific scope for the AR 15-22?
Not necessarily, but rimfire scopes have parallax adjusted for 50 yards, which matches .22LR performance.
2. What magnification is best for plinking with an AR 15-22?
Between 3x and 9x is ideal — anything more is overkill.
3. Can I use an LPVO on my AR 15-22?
Absolutely. LPVOs like the Primary Arms or Arken LH-6 work perfectly for dynamic drills.
4. Will these scopes hold zero on a .22LR platform?
Yes. The recoil of a .22LR is minimal, so quality scopes will maintain zero for thousands of rounds.
5. Is an illuminated reticle necessary?
Only if you shoot in dim light; for daylight plinking, it’s optional.
