i know from a little feild testing a few years back that vortex pronglike forked flash supressors are extremely effective at negating visible flash. as some here may already know from my various rants in the box im looking into building a .308 shorty auto and wondering what muzzle device i want on it. my question is about durability of the prongs when hot...for a high volume of fire scenario are those pronged tuning forks gonna bend into a mangled fail as soon as a ninja tard drops it or uses it to muzzle stroke a zombie in the forehead at a doorway? ive heard horror stories of birdcages melting into the bulletpath of dropped m4's from too much heat running tracer on field problems and wonder if this should be factored into what is basically a shtf weapon build. all thoughts will be apreciated yall.
