Thanks guys. Guess they are a lot stronger than I thought.
Suppressors are pretty strong typically, and a fall shouldn't damage the rifle or suppressor. Obviously there is a difference between walking through the woods and your sling failing, and dropping the rifle muzzle down from 40 feet onto concrete. The forces your rifle are likely to encounter are no big deal.
The lightest suppressor we ever made (size/weight) was a 8.5" long .45 caliber suppressor 1.375" OD made of welded 6061 aluminum- it weighed 5.5 ounces and had .06" wall. I supported the barrel at the chamber and suppressor at the muzzle and stood in the middle (220 lbs) - even bouncing up and down I wasn't able to bend the suppressor. It was serviceable and aligned prior to and after the test.
I was pretty surprised, I expected it to be bent badly.
The centerfire suppressors are 20-30 ounces and made of steel or stainless steel, so they are considerably stronger.
