A3 Industries Triad Bullpup Chassis, Black

The TRIAD bullpup chassis for Foxtrot Mikes upper receiver pistol is a meticulously engineered platform designed to enhance the performance and ergonomics of your firearm. Crafted with precision, this chassis is not a lower receiver but a robust framework that requires a compatible lower receiver to complete your build. Constructed from high-quality materials, the chassis features a 6061 aluminum front trigger housing and receiver, ensuring durability and lightweight performance. The front trigger is made from 17-4 stainless steel using metal injection molding (MIM) and is coated with QPQ for enhanced wear resistance. The inclusion of 4140 steel anti-walk trigger pins ensures stability and reliability during operation. The A3 Tactical ambidextrous selector, complete with a detent spring and detent, offers seamless operation for both left and right-handed users. The front trigger linkage, also crafted from 17-4 stainless steel with QPQ coating, provides smooth and consistent trigger pull. The chassis incorporates a 7075 aluminum transfer bar and rear linkage, supported by 841 oil-embedded bronze bushings for reduced friction and increased longevity. The Acetal Delrin guide and trigger actuator further enhance the smoothness of the trigger mechanism. The main chassis housing is constructed from 30% fiber-reinforced injection molded Zytel polymer, offering a perfect balance of strength and weight. Threaded chassis inserts made from 4140 steel and 7075 aluminum provide secure attachment points for additional components. For rifle configurations, the chassis includes a 6061 rear threaded buffer adapter and a 6061 rear butt-plate, along with a 1.5 inches extended butt-plate made from 30% fiber-reinforced injection molded polymer. An injection molded elastomer butt-pad and cheek rest ensure comfort during extended use. The chassis is equipped with multiple 4140 quick disconnect (QD) sockets for versatile sling attachment options. The mag release system features a 4140 steel mag release, a 7075 extended right-side mag release button and a 7075 left-sided mag release lever for efficient magazine changes. Additional features include an injection molded Zytel polymer front trigger housing cap and rear butt-plate support, as well as a rear cap with a 4140 quick disconnect sling socket for pistol configurations. The 4140 ball detent takedown pins ensure secure assembly and disassembly. Completing the package is the A3T XENO-patterned reduced angle polymer grip, made from 30% fiber-reinforced Zytel and the rise armament RAVE 140 drop-in trigger, providing a crisp and responsive trigger pull.
