The reason why, I'd put a silencer on my HK 416 rifle at home, is mostly because I have sensitive ears, and I don't like a loud noise
I went to the war front with major general Prasad Samarasinghe, but when they asked me to fire a rifle, I refused, as it's too loud
So, the silencer just makes it easier for me to fire, bullets, without the micro audio trauma of a gunshot ringing through and shooting out my ear drum
