These are the short rifles/carbines with the grenade launcher tube attached, and folding knife bayonet.
Looking down at the top of the gas block, one sees a figure 8 type cut, upper hole smaller than lower. There is a "button", it's moveable, that as the rifle came, rests against the grenade sight, in it's folded down position. The button must be moved into the figure 8 cut in order to raise the grenade sight.
I assumed that the gas system would be shut off when firing grenades, but have been told that a "ball round" was used to launch rifle grenades, which seemingly would obviate a gas cut-off.
Anyone know about this? Possibly, this button might allow removal of some part from the gas block for cleaning? Appreciate any information. Thanks.
