Expand Your Real Estate with the Kuna Rail Extension - 3.75" Your support hand shouldn't be fighting your weapon lights for space. Ever. The KDG Kuna Rail Extension is built for shooters who are done dealing with a cramped factory forend. Made specifically for the Springfield Kuna, this extension transforms your compact platform into a fully modular, suppressor-ready driver without adding unnecessary bulk. What Makes the Kuna Rail Extension Stand Out? Critical Hand Real Estate: Adds 3.75 inches of pure, usable mounting space to your forend, bringing your setup to a functional 7 inches of overall length so you can comfortably stretch out your grip. Keep Your Backups: Features a precision-machined clearance cutout designed specifically to accommodate front fold-down sights, keeping your backup zeros functional and out of the way. Surrounded by Mounting Options: Equipped with a solid Picatinny rail on top for switches and laser modules, paired with clean M-LOK slots on the bottom and both sides for lights and grips. Suppressor-Ready Clearance: Built with a generous 1.85" diameter, leaving plenty of room to tuck your favorite can neatly inside the rail for a seamless, low-profile look. Why Choose the Kuna Rail Extension? Drive the Gun Flatter: Get your support hand further down the handguard where it belongs for better muzzle control, faster transitions, and protection from forward muzzle blast. Flat and Intentional Design: Precision-machined from rugged 6061-T6 aluminum and finished with a Type III hardcoat anodize. No jargon pileups or corporate weasel words here-just pure functional dominance. You Had a Problem, We Solved It: The factory handguard was short on real estate. We don't follow the market; we build what it's missing, engineer it to look better, and make sure it can take a beating.
