When 700 rounds are fired in a continuous burst, there’s bound to be some type of reaction.
In this case, when a suppressor known as a Silencerco SWR branded can is used when firing 700 rounds in one continuous burst through a full-auto M249 SAW, it goes up in flames and begins to melt.
After only a few hundred rounds are fired, you can see the suppressor turn red and start to burn up. Around the 350 or 400 round mark, the can breaks up, but still manages to fire rounds through it.
Check it out, because this is one insane reaction to a dangerous test.
