The suppressor used in this video was a Silencerco SWR branded can. We fired 700 rounds in one continuous burst through a full-auto M249 saw. The can ended up breaking around the 350-400 round mark. The gun itself ran wonderful and had no problems.

The only problem we had afterwards was someone was going to have to clean it. We wanted to see how far we could push a full-auto rated suppressor.
The results are impressive, and although the suppressor basically disintegrated, failing around 350 rounds, it gave a good fight before doing so.
The suppressor starts to noticeably heat up approximately 10 seconds after the firing start. It bursts into flames five seconds later. The coup de gras comes 30 seconds into the test when the suppressors actually melts in half.
