The weakness of such a system is that it distributes hot gases and unburnt propellant directly into the rifle’s receiver, leading to overheating and potential stoppages if regular maintenance and cleaning protocols are overlooked. The cartridge was more powerful than the 5.56mm NATO, exacerbating this problem. This made the M468 less reliable than the M4 carbine it was trying to replace.

Barrett magazine was made of steel rather than aluminum and had a steel follower rather than an aluminum or plastic one. The magazine used two magazine springs instead of one to maintain steady pressure
