Speaking of AK-47s, how about an Integrally suppressed AK-47? http://redjacketfirearms.co...rifles/AKrifles.html
Integrally suppressed AK-47 in 7.62x39mm. Barrel is 8.5". Suppressor has inconel blast chamber and monocore baffle system.The quietest AK on the market.
I just saw it last night on TV. The suppresor lowers the sound level to 127 dbs as measured from a few inches from the barrel.
