Bushnell took the bedrock principles behind every scope they build-optical precision, rugged reliability and uncompromising performance-and pushed them even further to create an incredibly versatile Red Dot Optic for modern shooters. Equally at-home on handguns, rifles and shotguns, the TRS-125 features a point-source LED that creates a clean, crisp beam that produces a strong, daylight-bright 3 MOA red dot with 10 brightness settings. The TRS-125 features a monolithic main housing made from aluminum, and is IPX7-rated to be 100% waterproof and submersible to 1 meter for 30 seconds-so you can count on the highest level of durability in the worst weather. The 12-hour auto shut-off features helps preserve the battery, so you can expect over 15,000 hours of operation on (1) CR2032 battery. And best of all, it's backed by Bushnell's Ironclad Warranty.
