for your survival rifle. it's stupid, but for the moment, let's engage in trying to work around this stupidity. You could have a silenced 308 auto, a very long, bulky package, and a silenced .22 handgun, for small game. perhaps with a battery dependent optical sight, it could even serve for braining a man or a dog, to 10 yds or do, or a deer, but the .22 unit on the 223 AR would give you a LOT more effective range. The 22 handgun is so bulky and heavy that it probably precludes your also having a pocket 9mm, but perhaps not
However, practice with that handgun wont make you more skilled with your 308. practice with the .22lr unit on the AR, (without the silencer in place) WILL make you more skilled with the (silenced) AR.
If you cut the 308's barrel enough to make the gun handy with a silencer, much less to make it concealable while taken down, you lose all claim to more effective range than a shorty AR offers you (in 223) Your velocity from an 11" 308 barrel, will be 2300 fps, at best, with hot loaded 150 gr boatails, which aint a lot of power, about like a 30 AK (at best) 1550 ft lbs
