"All AR parts are made by the same company." We at Charlie's have lost count of how many times we have heard this. Many shooters will spend their budget on the latest fad accessories and skimp on the basics. Here we believe that cheap parts are just that, cheap. Make sure to use quality internals on your builds.
Sprinco has a strong reputation in the industry for making some of the best springs available. Using only the highest quality materials and processes, Sprinco recoil springs can actually outlast the barrel of the host weapon and with greater heat degradation resistance compared to standard springs. With consistent pressure throughout the life cycle of the spring, many weapons will have fewer malfunctions due to aging and wearing springs. High round count shooters will also appreciate having to replace multiple lower quality springs over the service life of the weapon.
For easy identification, the end of the springs are stained using a metal dye. These are available in different power levels to allow for tuning the gun, for example, a weapon with a high back pressure silencer.
