The chrome silicon flat-wire spring increases the service life of the AR platform, smooths out the shooting cycle, and greatly outlasts the stock spring. In addition, it has a more linear compression with less stacking and increases reliability.

|Initially it was hard to install, so I oiled it and that fixed the stiffness. It's still a bit hard to pull past the detent pin if you are removing, but it's not impossible. The flat spring does leave a little rusty residue on the buffer weight. Overall I am pleased with the product|
