This video delves into the Steyr ACR, a bullpup rifle developed for the US Army's Advanced Combat Rifle program in the early 1990s. Aimed at significantly improving the M16's accuracy, the program explored concepts like high-rate burst fire and flechette ammunition. The Steyr ACR, with its polymer construction, low-power optic, annular gas piston, and unique vertically sliding chamber, is examined. Despite its innovative design and features like a 1200 rpm rate of fire, it ultimately failed to meet the program's demanding accuracy standards, contributing to the cancellation of the ACR initiative without a clear winner.
This video delves into the history and design of the Walther A115, a rare pre-WWII German semi-automatic rifle. The description highlights its unique sheet metal construction, rotating bolt, and annular gas piston system, noting its similarity to later G41 rifles. It's mentioned that only three prototypes were produced. The example in the video was examined by Aberdeen Proving Ground in 1955 before entering private ownership. The content focuses on historical firearm development and unique engineering aspects.
