After reading the description on the identified parts HERE it seems to indicate they are designed to specifically work for what you're indicating you want to do. Not having purchased these particular springs, I can't say if they're good, bad or indifferent. Hopefully a fellow Bolter or two has and can chime in and offer their thoughts/experiences.
