Does anyone know what are the holes in front of the VIS-3 receiver for?
Thanks,
Igor
It looks like the rails are cut around the holes too… Strange.
I haven’t the foggiest, but I’m sure someone here knows.
The size of the cutouts around the inner two appear to be holes to attach a sling mount. I’m not sure about the forward most hole.
I believe it’s for M203 mount.
mute’s got it right. directions come listed for one’s unit armorer to install an M203.
