SIG Sauer 8100307-R is the front-cap wrench for SIG's .45 pistol suppressors. When a front cap is carbon-locked, this is the factory tool that fits the cap so you are not chewing it with pliers.

It is a .45 front-cap wrench, not a dual-hex rifle-can spanner and not a piston wrench. Use it with the suppressor unloaded, cool, and pointed in a safe direction. SIG's pistol-can manuals call for a factory tool to remove the front cap before the baffles come out.

This listing is the .45 front-cap wrench only.
