None. There may have been less.
I'll give a quick run down on how a suppressor works.
Suppressors act as a muffler. They trap the gasses spent behind the projectile to bring the decibel rating down to a hearing safe level.
The quieter the level and more efficient the suppressor is... the hotter and dirtier a semi or fully automatic weapon will run.
A standard run of the mill carbine AR gas system, which is direct impingement system, utilizes the front sight base as a gas block to route some of the gases from combustion through a gas tube which goes back to the upper receiver to drive the bolt carrier group rearward to eject the spent cartridge and the buffer and spring push the bolt carrier forward grabbing the next cartridge in the magazine.
What happens when you throw a can on an AR? You increase the back pressure, increases the gases and carbon fouling back to the bolt. The faster you shoot the quicker things get dirty. Inducing failure to cycle.
What a suppressor does not do. Is eliminate the sonic boom, the crack of the projectile down range.
In a 16 inch upper. A2 front sight post with a run of the mill 223/5.56 suppressor that thing still goes Boom. Just not deafening boom.
When you run the gun at a faster rate. Halfway through the 4th magazine the gun failed to function. The first failure was a short stroke. The bolt didn't get enough gas from a build up of carbon residue to strip a round out of the magazine. It didn't cycle back fully.
Manually cycle the next round. It managed to cycle. Stripping the next round just fine. Following shot stove pipe. The bolt didn't travel fully rearward and the buffer and spring slammed the bolt carrier home on the spent case. Gun jammed.
I needed a can of brake clean to clean out the gas tube and gas block/front sight post. The carbon fouling was so heavy on the bolt carrier and in the upper receiver it needed to be cleaned. In between the upper an lower receivers was heavy amount of carbon fouling.
In this case. The shooter would have taken himself out with a self induced failure with a suppressor. Especially an effective one that would make the muzzle report quieter. Less rounds down range.
The same thing happens with AK long piston system. The gas block fouls with carbon and the firearm fails to cycle.
