Frequently Asked Questions

What are the key features of the Surefire X400 weapon light and laser combo?

The Surefire X400 boasts a robust aerospace-grade aluminum construction, 1110 lumens of white light output, and an integrated laser aiming device. It's designed to hold zero through hundreds of rounds and offers a dedicated system for illumination and aiming.

How does the Surefire X400 improve rifle shooting at close distances?

For rifles, the X400 can be mounted to provide a point of aim/point of impact solution at close ranges (around 21 feet). This allows for rapid target acquisition using the laser, bypassing the need to offset optics or iron sights, especially in dynamic situations.

What is the recommended mounting procedure for the Surefire X400?

Mount the X400 by aligning its crossmember bar with the rail slot, loosening the thumb screw, indexing the unit, hand-tightening until a click is felt, and then using a tool for a more secure fit. It's advised to use a dedicated holster to maintain zero.

Is the Surefire X400 laser a replacement for traditional firearm sights?

No, the Surefire X400 laser is considered a supplemental aiming device. While it offers advantages in specific scenarios like unconventional positions or for those with failing eyesight, it's not a replacement for iron sights and should be used to enhance, not substitute, fundamental marksmanship.
