AimShot BS204 Laser Bore Sight .204 Ruger Red

The AimShot BS204 is a cartridge-style laser bore sight chambered for the .204 Ruger, designed to drop directly into the chamber of any .204 Ruger rifle and project a red laser dot down the bore for fast scope or iron-sight alignment at the bench.

Built around a solid brass housing machined to mimic the dimensions of a .204 Ruger cartridge, this bore sight delivers a 640nm red laser with an output of less than 5mW, placing it in the FDA Class IIIa category. Power is supplied by three LR41 button-cell batteries (also sold as L736), giving roughly 20 minutes of continuous run time per set, more than enough to get a scope dialed in before swapping to live ammunition.

The BS204 is sighted for a working range of 3 to 100 yards, covering the typical zero distance for a varmint or centerfire .204 Ruger rifle. Because it is chamber-specific, it seats in the bore exactly the way a loaded round would, removing the guesswork of centering the reticle on a fresh scope installation or after a mount change.

Compact enough to live in a range bag or bench drawer, the BS204 measures 1.10" x 4.95" x 6.75" and offers a quick, repeatable starting point before heading to the line.
