It looks like you have a pin that has a screw-on backer for extra security. If you need an extra set, those will work, but I have extras if you want. (free)
Remeber that manual that came with you gun that you probably threw out saying "pssh manual? just aim and shoot" It has a parts list on the CA website they have some manuals for some guns. How old is it?
also i'm assuming it's a CA due to the lower reciever but same applys for most other guns
Yep, it's a Classic Army It's about 3-4 years old so pretty old. Thanks for offering free ones but i'm going down to the hardware store tomorrow to get it so it will be cheap, and my dad's paying for it.
