Sightmark .300 Boresight

Took this to the range and the red laser dot stayed perfectly aligned after several shots. Chambered smoothly and made zeroing quick and easy.

The red laser dot held zero perfectly after I chambered it in my .300 Win Mag, which saved me a ton of time at the range. Exactly what I needed for quick sighting in before deer season.

Chambering it like a normal round and seeing that red dot land exactly where I aimed took all the guesswork out of my zero. The laser was bright enough to pick up clearly even on a sunny afternoon at the range.
