If you've lost, damaged, or worn out the rear cap on your Surefire M300 or M600 tactical flashlight, a replacement rear cap gets your light back in service fast. This genuine Surefire replacement part ensures a proper seal and reliable performance on either model—whether you're running duty gear, building out a rifle setup, or keeping a proven light in rotation. Surefire's track record with tactical flashlights means the engineering here is solid; a replacement cap isn't an afterthought, it's a critical component that protects internal electronics and battery contacts.
Tactical flashlights earn their reputation through consistency under stress. The rear cap does more than close the battery compartment—it seats against the light body to weatherproof the interior and maintain contact integrity. If corrosion, damage, or simple wear has compromised yours, replacing it is cheaper and faster than replacing the entire light. This is the kind of spare part serious shooters and first responders keep on hand.
Whether you're replacing a cap that's seen hard use or stocking a backup for a light already in your kit, this Surefire original part maintains the same fit and function as factory equipment. Order with confidence if you run an M300 or M600.
