Top 5 Best Red Dot for Remington 514 of 2025

Finding the best red dot for Remington 514 can be a rewarding upgrade for anyone who enjoys this timeless bolt-action .22 rifle. The Remington 514, introduced in the 1940s, remains a favorite for training, plinking, and small-game hunting. However, its simple iron sights often limit accuracy for modern shooters who demand faster target acquisition. That’s where a compact, durable, and precise red dot sight makes all the difference.
In this review, I’ve hand-tested and compared several red dots that mount securely on the 514 (with or without adapters), providing crisp dots, long battery life, and excellent performance for the rifle’s capabilities.
