This largely depends on which marker you have. A double trigger will help and also a electronic grip frame will as well assuming your marker can accept a new frame of any kind. Keep in mind that the hopper will also need to be able to keep up with a higher rate of fire or you will encounter chopping problems. For most situations it is typically better to replace the marker with a different one that has a better rate of fire rather than trying to modify an existing marker. While modifying can be done, the cost of a new trigger frame is typically about half of the price of another, faster shooting marker that will also have more features. Do some research before spending money.
This is a Nelson 707. It was made originally for marking cattle or trees and was later adopted for the earliest games of paintball. It is the predecessor to the Nelspot 007 marker.
