This Ruger 10/22 has a bull barrel with an integrated sound suppressor.
Her name is Bane. Short for Squirrels Bane.
If I could pick only one firearm as a survival gun it would be Bane. It is very light weight, easy to shoot, and so quiet it amazes me every time I pull the trigger. This is a great first gun for kids, novices, women, (or anyone) to shoot. Great for a level 4 Zombie outbreak.
The Tapco stock on it is the best one I have found so far. I will get a quality 4x scope and powerful tactical light for it one day.
--I am still searching for the best quality brand, high capacity, mags for the 10/22.
