This review delves into the AAI 2nd Gen SPIW flechette rifles, prototypes from 1966-1967 designed to replace traditional rifles with high-velocity flechette ammunition. Despite impressive muzzle velocity (4,585 fps) and a unique primer-activated operating system, the program faced significant reliability and accuracy issues during trials, particularly with mass-produced ammunition. The 1967 model introduced improvements like a barrel radiator to address cook-off problems.
The Winchester 1964 SPIW was a prototype developed for a 1962 U.S. military program seeking a multi-purpose combat rifle. It featured flechette ammunition for point targets and an integrated 40mm blow-forward grenade launcher. Despite innovative concepts like a soft recoil system, the SPIW suffered from poor balance and reliability issues, ultimately failing to be adopted.
