In about two weeks I should be recieving some springs I'm having made for aftermarket conversions. The process will involve replacing the factory spring with a MUCH STIFFER one. I will of course, return the factory spring with the end caps along with the knife. I'm sure there are quite a few Halo2 owners who would like a lot more "kick" along with added reliability. I'm not yet sure how much I will be asking for the conversions, that will depend on the cost of the springs. I will post my e-mail address when I get the springs. Anyone interested??
