Now, thanks to Chrome Silicon technology, it will keep on running! The SpeedLock CS Spring line now adds an AR15 Trigger Return and Hammer Spring set.

This set lets a gunsmith tune an AR15 trigger and know it's going to stay where he set it. These rifles are notorious for changing trigger characteristics, and one of the main culprits is cheap springs. Our CS springs stop that. These replacement parts embody all the advantages of our superior Chrome Silicon material. CS Springs offer greatly improved performance, and each CS Spring is the same, part to part to part. That means trigger characteristics and performance quality can be relied on.
