The most common side effects encountered when shooting suppressed (especially with the M16/M4) is increased back pressure as well as an increase in the cyclic rate. This is due to the fact that the gases are being "retarded' and diverted by the baffles. You will also see a drop in the muzzle velocity as well.
This is why it may also be necessary to change buffers when shooting suppressed. For example, my 11.5" would cycle 100% using an H2 buffer, but I would not get 100% magazine lockback everytime. Once I went to an H3 buffer the problem was solved.
The baffles work by slowing down and traping the gases before they leave the barrel as well as allowing it to cool.
