M511A 84871505116
The SureFire M511A replaces the original triangular-cap handguards of your M16/AR-15 or similar rifle. It features a 9-volt shock-isolated incandescent lamp with a 1.62" reflector suited to close- to medium-range applications. Primary beam output is 125 lumens for one-hour of runtime using an MN10 lamp assembly (included) or 225 lumens for 20 minutes using an MN11 lamp assembly (included). The M511A has three primary beam switches integrated into the forend: a constant-on rocker switch (left side), a momentary-on pressure pad switch (right side), and a system-disable rotary switch (rear of battery housing) that locks all lights in the OFF position to prevent accidental activation during covert operations, transport, or storage. The navigation lights are operated by a smaller momentary-on pressure pad switch (left side). Proven in combat, used by military and law-enforcement around the world.
