Larue Lt178 Ruger 10/22 Top Rail
The LaRue Tactical LT178 is a 6-inch Picatinny rail designed to mount directly on top of your Ruger 10/22 receiver. This aluminum top rail gives you a rock-solid platform for mounting optics, red dots, or other accessories without the wobble of removable mounts. If you run a 10/22 for training, competition, or casual plinking and want to add glass or electro-optics, a dedicated top rail beats improvised solutions every time—it's engineered to stay put and repeatably return to zero.
LaRue has a well-earned reputation for no-nonsense mounts and accessories, and this rail follows that philosophy: straightforward, durable, and built to function. The 1913 Picatinny standard means any accessory with that footprint will lock down securely. Whether you're upgrading a stock 10/22 or building a more capable rimfire platform, this rail integrates cleanly into the receiver's top and keeps everything in line.
Installation is straightforward for anyone comfortable working on their 10/22. Once mounted, the rail provides maximum real estate for optic placement and lets you dial in eye relief and mounting height exactly as you need it. It's a practical upgrade for shooters who want to move past iron sights or clamp-on rings.
