They all do that to some degree. Its totally normal. Its one of the things I love best about it as it makes a very distinctive sound when firing at the enemy...
Some stocks transmit the sound better than others. Spend anytime with an a2 rifle stock and you can tell by the sound and feel if the gun is running right. I like the feedback as its an instant cue if something is wrong.

The problem with being stupid is you cannot simply decide to stop doing dumb things...
