Dead Foot Arms Underfolder 4" Rifle Kit

This compact rifle kit from DFA features a robust underfolder stock system with a left-side button release for streamlined deployment and secure lockup. Designed for minimalist builds and SBR conversions, the 4" barrel configuration delivers ultra-short overall length while maintaining compatibility with standard 7.62x39mm platforms. The kit includes a precision-machined trunnion, reinforced receiver components, and a threaded muzzle for brake or suppressor installation.

The underfolder mechanism folds tightly against the receiver for transport and storage, while the left-side release button offers intuitive operation for right-handed shooters. Ideal for tactical builders, collectors, or AK enthusiasts seeking a unique footprint, this kit blends classic military styling with modern modularity.
