Ammo feeder for M60

[Machineguntony]

I bought an M60, and I am I'm the process of gathering all the gear for when Dr. ATF tells me that I can bring home my baby. The M60 guide says that it is not advised to shoot using loose belts, as loose belts can damage the top cover of the M60. It says to use an ammo pouch, which can be mounted on the side of the M60.

Is this the ammo pouch that is used to feed the M60? I can't tell if that's the pouch that feeds the M60, when it is attached to the gun, or if it is just a pouch that carries rounds around the gunners waist.

One is 100 rounds, the bottom one is 200 rounds.

Thanks.
