Well, for $10 bucks what do you have to lose? Well, i can tell you there is no losing, only winning. Take action screws out, take trigger screw out, take out adjuster screw (do not lose it) and tip it toward your hand. A spring and a little rod fall out, pay attention what direction the rod came out, put rod in new spring and drop em in the hole, put adjuster screw back in and trigger bolt, and action screws(torque all screws/bolts to manufacture specs) and you're done! I set my adjuster screw until it touched the trigger screw (assuming that’s about as light as it can go) and was way lighter and didn’t slam fire! (Adjust and test your own, your rifle may be different). It’s as good as $200-dollar triggers i own, so don’t waste your money.
