What is a knex sear trigger and does somebody has a video about how it works? Answered
I wanted to make an knex Spas 12 since it's a really epic gun.
I saw some and most of them didn't have a real pump action system. So I thought I could make one on my own.
I spent 3 days working but I had trouble with the trigger and pump system.
Some people said I had to use a sear trigger but I didn't understand. Help?!
