Applying cold therapy to a tissue injury, helps limit the inflammation by causing the blood vessels to constrict. This in turn helps to limits the blood flow to the injured site, which helps to moderate the release of the vasoactive substances and therefore helps minimizes the pain and swelling in the injured area.
Kangaroos go down easy with well placed .22LR shots, so a .17HMR or .22WMR will not be a problem. I've got both a .17HMR and a .22WMR, I prefer the .17HMR mainly because it shoots flatter, making it better for rabbits, and will easily take a fox out to 120m at least (provided you placed your shots ;)).angaroos go down easy with well placed .22LR shots, so a .17HMR or .22WMR will not be a problem.

As for AR pistols, they assemble easier, but you have to deal with the pistol buffer sticking off the rear and can have cycling issues with a short barrel at 10-11 or less, plus they cost more. For a pistol, the AKs are fine, I just leave them stock.I've had 4 Yugo AK pistols, two M92s and two M85s, all of which shoot perfectly fine and accurately with and without the Krinkov brake or 4 piece muzzle brake. If your trying to convert a AK pistol into a tactical firearm, then stick to a AR or a PDW, not a AK.s for AR pistols, they assemble easier, but you have to deal with the pistol buffer sticking off the rear and can have cycling issues with a short barrel at 10-11 or less, plus they cost more.
