it was my understanding that these proceedures were dumped because of the danger of
firing a live round into the back of a live rifle grenade......with the attendant results !!
i also understand that a new generation of grenades has been developed with a built-in
bullet trap, so that ball ammo could used....either to launch the grenade , or simply
protect the firer from fragging himself . i know that when colt first picked up the AR15 ,
they offered a clip on grenade sight which attached to the FSB via a small projection on it's
front . i've seen exactly one of these over the years.....and still kick myself for not buying
it . if i can readily get this equipment , i'd like to at least think about building a dedicated
"grenade gun" the old gun show staple practice grenades are actually fairly accurate out
to about 75-100 meters .
