Radian Weapons Compressor Guide Rod Features The Radian Weapons Compressor Guide Rod eliminates the cap screw found on most adjustable guide rods replacing it with a screwless dovetail interface that is secured by the spring itself. That design solves a real problem with traditional adjustable guide rods where loose screws can work free over time and thread lockers force shooters into a single fixed spring weight. Flutes machined along the length of the guide rod let the recoil spring move with less friction resulting in smoother more consistent slide cycling shot after shot. A heat-treated rod body stands up to the repeated stress of slide cycling without deforming or wearing prematurely. Finished with a durable corrosion-resistant nitride coating the Compressor Guide Rod is built to hold up under range use duty carry or competition. Because the design is screwless shooters can swap spring weights quickly to tune recoil impulse for different ammunition or use cases without fighting a stuck screw. This direct-fit guide rod is designed specifically for the Glock 17 in Gen 3 and Gen 4 configurations ensuring proper fitment without modification. For Glock 17 owners looking for a more reliable and tunable guide rod system the Radian Weapons Compressor is a smart upgrade available for sale at GrabAGun.
