Choosing the best scope for FX Impact isn’t just about magnification—it’s about pairing the most advanced air rifle in the world with optics that match its precision.
The FX Impact is a modular, highly tunable PCP rifle capable of sub-MOA accuracy at long ranges, and it deserves glass that complements its performance. I’ve tested and compared several scopes across various shooting conditions—from pest control at 50 yards to precision targets beyond 150 yards—to bring you the most accurate and practical options available today.
Below are my top picks for FX Impact shooters who demand the perfect balance of clarity, tracking, and airgun-specific adjustability.
