If you've been around BR for some time, you've heard the stories about a particular action that wont shoot no matter what barrel you put on it. Many times it can be traced back to the ignition mechanism. These actions are not the norm however, rather the exception. Dwight's spring and bushing kits can help to make such an action perform better. But until you have put your action through its paces with the original firing mechanism, you don't know if you have a problem. Now while a shooter with a very deep knowledge of BR may be able to tweak an already good shooting gun into a great shooter with a kit like this, a novice would be pissing into the wind until he learned how to play this game. Also, these mods aren't exactly a drop in fix either. Sure you can put a new spring an bushing in pretty easily, but fine tuning is what these things are all about. The springs come long and need to be trimmed to the proper length for the proper amount of tension, and I've found that the bushings need to be tuned (lightened) to the proper weight also.
