The Firefield .223/5.56 Laser Bore Sight (brand part no. FF39016) gets a rifle on paper in minutes instead of burning a box of ammo walking in a zero. Sized specifically for .223 Remington/5.56 NATO, the bore sight seats directly in the chamber and projects a red laser dot exactly where the barrel is pointed, letting the shooter adjust their optic or iron sights to match the theoretical point of impact before ever pulling the trigger. From there, only a few rounds of live fire are needed to fine-tune for bullet drop and windage. It’s a fast, repeatable way to zero a rifle at the range or in the garage.
