Juggernaut AR-10 Hell Fighter Mod Kit Features The Juggernaut Tactical Hell Fighter Mod Kit is a patent pending bolt on solution designed specifically to give California compliant AR-10 owners a faster way to change magazines than a traditional featureless bullet button setup. At the heart of the system is a modified quick release takedown pin that doubles as an operating button separating the upper receiver from the lower just enough to disengage semi automatic function. This action simultaneously disables the magazine lock making the standard magazine release fully operable for the moment the upper is separated. Once the shooter has swapped magazines a simple tap closes the upper and re-engages the spring loaded takedown pin restoring the rifle to its compliant locked configuration. Constructed from stainless steel for durability and corrosion resistance the Hell Fighter kit is built to withstand repeated use without excessive wear on its moving parts. This AR-10 specific kit is compatible with rifles using either a back fed or bottom fed magazine release detent giving it broad compatibility across different AR-10 builds. The result of a full year of engineering and testing this kit lets California shooters perform magazine changes dramatically faster than they could with older compliance solutions. For AR-10 owners in restrictive states who want speed without sacrificing compliance the Juggernaut Tactical Hell Fighter Mod Kit is a purpose built answer.
