Space bar to fire (3-round bursts only) R to reload In 1987, the U.S. Army initiated a program to select a new combat weapon for American soldiers, named the Advanced Combat Rifle (ACR) project. Four companies, AAI, Steyr-Mannlicher, HK, and Colt participated and entered their own futuristic-looking designs. Steyr-Mannlicher entered a weapon based on their well-known AUG. This weapon fired a carbon-steel flechette round from a 24-round proprietary magazine on 3-round burst mode at 1200 rounds per minute. It uses a vertically sliding chamber rather than a horizontally-acting bolt as seen on most other weapons, with the chamber held down to feed a round from the magazine. The trigger releases the chamber to slide upwards, aligning the round with the barrel and then firing it. All of the weapons in the ACR program failed to replace the M16A2 in American service, and the M16A2 was replaced with the M4 carbine, firing conventional ammunition.
