Why in the Sam Hill did Gene Stoner design the direct gas-impingement system in the first place?
How much of the weight savings is now eaten up by additional magazines. I don’t see the benefit in this new light machine gun.
There are a couple advantages to the design. The excess gas is vented from ports in the bolt, making it somewhat self adjusting as opposed to the FAL adjustable gas system. Also, there is no reciprocating weight of a piston, which reduces felt recoil and greatly enhances full auto control.
