Most adjustable guide rods on the market use a cap screw to retain the spring. The problem? Loose screws are too common and thread locker forces you to commit to one spring weight. - Enter the screwless design of the COMPRESSOR Quick-Tune Guide Rod. The dovetail interface is captured by the spring creating a simple and secure lock-up. Flutes along the guide rod allow the spring to move with less friction for smoother cycling. The heat treated guide rod has a slick durable and corrosion-resistant Nitride finish. - Includes: - 1 Hardened 17-4 SS Guide Rod - 3 Flat wire Springs in 13lb 15lb and 18 lb weights - 1 SS Washer for Gen3 - 1 SS Captive bushing for Gen4 & Gen5 compatibility - 1 Spring compression tool - For GLOCK G19 GEN1-5 G19X and G45
