5 Best Scope for AR 22LR: Precision Optics for Rimfire Fun and Accuracy

Finding the best scope for AR 22LR is all about striking a balance between light weight, optical clarity, and reliable adjustment tracking. The .22LR cartridge is legendary for its affordability and low recoil, making it perfect for training, target shooting, and small-game hunting. But to truly extract the accuracy potential from your AR platform, you need a rimfire-optimized optic that matches its performance curve.
Over the past year, I’ve personally tested and compared dozens of optics—from budget-friendly entry scopes to premium-tier glass. I mounted them on a Smith & Wesson M&P 15-22 and a CMMG .22LR upper, zeroed each at 50 yards, and tracked how they held zero across hundreds of rounds.
In this detailed review, I’ll walk you through the top picks, full hands-on reviews, and a practical buyer’s guide to help you find the scope that suits your .22LR AR setup perfectly.

🔧 How to Choose the Right Scope for Your AR 22LR

When selecting the best scope for your AR-22LR, focus on these factors:
Magnification Range: For plinking or target shooting, 3–9x is ideal. If you shoot under 50 yards, even 1–6x LPVOs work great.
Parallax Adjustment: .22LR rifles benefit from parallax settings at 50–75 yards rather than 100+ yards.
Reticle Design: Choose simple reticles (Duplex, BDC, or ACSS Rimfire) that help estimate bullet drop at common rimfire ranges.
Weight and Size: Keep total rifle balance in mind. Lightweight scopes under 14 oz feel best on AR rimfire builds.
Durability and Warranty: Always go for scopes with proven shockproofing and a lifetime warranty (Vortex, Leupold, Primary Arms).

❓FAQs About Scopes for AR 22LR

Q1: What magnification is best for .22LR AR rifles? A 3–9x scope is versatile enough for both close and 100-yard shooting.
Q2: Do I need a parallax adjustment? Yes, ideally 50-yard parallax is perfect for rimfire accuracy.
Q3: Should I choose FFP or SFP for .22LR? SFP is better for casual or hunting use; FFP suits competitive shooters.
