Last year I spent over $1,000 getting my house repaired from squirrel damage. One of the squirrels is back nibbling on our bird feeder. my BB gun has not up to the job anymore and I am thinking of an airsoft gun with a high rate of fire that would be non-lethal. What would you guys recommend I have got a awesome field of view into the Backwoods and just need something to have a little fun chasing the squirrels away. Thoughts?
