Be sure your weapon is unloaded first off.

Second, slide the slide back to the point that the bolt is halfway open in the ejection port.

Third, unscrew the barrel takedown screw/magazine cap and remove the barrel.

Fourth, use a slide tube nut wrench to fit into the two slots on the slide tube nut and unscrew it.

Slide the forearm off and slide the Surefire back on.

Replace the slide tube nut, tighten it, and replace the barrel.

If you don’t have access to a slide tube nut wrench, you have three options. One is to carefully use a pipe wrench on the tube nut to loosen it….and if you do, be SURE to use padding so you don’t scratch it. Two is to use a pair of pliers (with padding again) to loosen the mag tube itself and slide it out of the slide tube. Three is to field strip the weapon and remove the entire action slide tube from the weapon. For two and three, a straight knife blade can then be used to unscrew the nut instead of the nut wrench.

If you go the route of removing the magazine tube, be sure to pad your pliers well to avoid scratching the magazine tube, and don’t grip it ANYWHERE except the last half inch at the tip where the barrel takedown screw attached. That last half inch is the only solid part on the tube. You don’t want to accidentally bend the magazine tube with your pliers.
