Earlier today (before they went out of stock) the Crosman 1377 was pretty inexpensive... and now I find that Walmart has this complete Crosman Doomsday Bug-Out Survival Kit [walmart.com]
with .22 Air Rifle and accessories for only $69. I've seen it for around $89, but the stock alone on this rifle is over $20, and the gun normally sells for over $45. You get a backpack, pellets and more for only $69.
I have the .177 1377 version of this gun, and it is one of the most hardnosed, accurate and versatile guns you'll find, and this .22 version is very good as well.
If you purchase something through a post on our site, Slickdeals may get a small share of the sale.
