DONT DO IT!!!! When i was still a kid (last year) i almost lost a finger a tooth and half my manlyhood by a relic airgun that is way underpowered snapping close on me. It wasnt much fun. It is is not fun to lose a finger.
Question: Why dont clowns eat people?
Answer: Because it is not funny!
The anti beartrap doesn't do any damage or harm, so leave it in place. If it caused a problem I would have agreed with taking it out. It is there for a very good reason.
Rather spend time on tuning the gun...
