/diy/ - Do It Yourself

Hey /diy/ I come for help

I am working on a firing pin assembly for a cosplay rifle (AR2 from Half-Life 2) and have found a bit of a problem with my design. In the game the firing pin moves horizontally like this: https://www.youtube.com/watch?v=CPnmCaO568E

Currently I am using a solenoid to dive the firing pin directly, but this only gives me a stroke length of 40mm (at the limit of using a solenoid). The problem is that I need the stroke length to be at least double that (80-100mm). So, the question is, would yous know of a good way to mechanically amplify the linear motion? So far, I am thinking of using a rack & pinion combination like this https://i.imgur.com/VUa14gc.jpg

I have thought of using linear motors or servos but the issue is that they won't give me the speed or thump I am after
