Radian Weapons Compressor, Guide Rod, Nitride Finish, Black, Fits SIG P365

Most adjustable guide rods on the market use a cap screw to hold the spring in place. The problem? Loose screws happen too often, and thread lockers force you to pick a single spring weight. Enter the screwless design of the COMPRESSOR Quick-Tune Guide Rod. The dovetail interface is secured by the spring, providing a simple and reliable lock-up. Flutes along the guide rod let the spring move more smoothly with less friction for better cycling. The heat-treated guide rod has a sleek, durable, and corrosion-resistant Nitride finish. • Screwless-Design, Quick-Tune Guide Rod • Fluted Guide Rod for Smoother Cycling • Heat Treated Guide Rod • Nitride Finish
