The Sig Sauer Foxtrot4R delivers professional-grade illumination with 1350 lumens of white LED output, engineered for tactical applications where reliable target identification matters most. This weapon-mounted light combines aerospace-grade aluminum construction with advanced LED technology to provide consistent performance in demanding conditions.
What Makes This Different
The Foxtrot4R stands apart from standard weapon lights through its optimized beam pattern that balances throw distance with peripheral illumination. While many tactical lights focus purely on maximum lumens, this system delivers controlled light distribution that prevents tunnel vision during close-quarters scenarios. The integrated rail mounting system locks securely without requiring additional adapters or hardware modifications.Key Features
