The Realtree camouflage 3-9x40 Trophy XLT Riflescope from Bushnell is designed as a versatile scope for medium to long-range use in all weather conditions with low-light performance provided by a large 40mm objective lens. The fully multi- coated optics reduces light loss to provide bright and clear images, while the nitrogen-filled and O-ring sealed housing ensures water and fogproof performance.
