AAI 2nd Gen SPIW Flechette Rifles
This video explores the AAI 2nd Gen SPIW flechette rifles, remnants of a failed military program that began in 1962. The SPIW (Special Purpose Individual Weapon) program aimed to develop advanced rifle systems, with initial trials from Colt, Springfield, AAI, and Winchester proving unsuccessful. AAI continued development, producing these second-generation rifles chambered for the XM-645 5.6x57mm single-flechette cartridge. Despite further testing, these rifles suffered from significant reliability, noise, cook-off, and accuracy issues, ultimately leading to the program's failure. The video showcases the rifles and provides historical context, crediting the Rock Island Arsenal Museum for access.
