Count me as one who thinks the GL is useless...bayonet too...might as well be carrying a full length rifle in a full power rifle cartridge. Launching golf balls or fake grenades doesn't do anything for me...shot enough real ones out of an M203 in the military to satisfy me. If it doesn't explode on impact and destroy something what's the point? So I removed the GL on my 59/66, also the bayo, bayo mount, GL sight and flip up night sights. I cut the barrel down to 18" and recrowned, then I ground the front sight assembly down to just the front sight and reinstalled it back into it's original position. Now I have a handy carbine without all the extra weight and length to deal with. I have an M59 also...it remains untouched. My 59/66 was a beater and I bought it as a project gun...would not have cut up a nice one. But then again I wouldn't have bought a nice 59/66 to begin with...too long and heavy a rifle for the cartridge IMO.
