fellas what was the purpose and effect of the full cone type flash hiders, sometimes called 'rocket nozzles' as seen on the enfield jungle carbines and some machine guns of the era. There seems to be a bit of 'bro science' and urban myth surrounding flash supressor conversations on the net and I am trying to discern the facts. I assume reducing signature to the enemy is probably inneffective, but I can see they might reduce the impact to the firers night vision to be able to direct the flash forward? I was also wondering if since they direct the exiting flash forward they might reduce percieved noise to the firer somewhat. Sort of the reverse effect of a muzzlebrake?
