I have an old daisy red ryder .177 BB gun, it's pretty beat up but still functions perfectly, would be great for teaching your kids to shoot with! 15$
Second is a power line model 1200 c02 .177 BB pistol, it has been modified with a buttstock and is set up to accept a scope which it had until the scope recently broke so I removed it. I This one is also pretty beat up and is missing the rear sight but also functions perfectly. I also have 4 c02 canisters for it. 20$
30$ for both obo. You can also have whatever BB's I have left over if you buy both.
