Put the negative side of the battery down the battery unit, then put the other two batteries in the same way, all negative side down. Then again, put back the battery cover with a hex wrench.

Step 2: Mount the Rail

Turn the bolt of the laser sight counterclockwise with a hex wrench to loosen the bolt. Snug it onto one side of the rail by facing it forward. Reinstall the bolt with a wrench. Point the handgun in a safe direction to see if it works properly.
