This is my newest "Backpack/ATV/Truck-Gun". It is a Troy Pump-Action Rifle (PAR) with a 9" .300 Blackout Barrel, producing a manually-operated firearm 30" long and weighing 7 lbs that launches .30 cal projectiles with ballistic properties similar to the Russian 7.62x39mm standard military intermediate cartridge. Hits out to 300m on the vitals of a deer-sized animal are easily managed. Really though, I carry it mostly for peace of mind as a legal last line of defence against the local Bear threat in the Northern Alberta wilderness. It fits very handily into its forward mount on my ATV!
