Chamber-loaded laser alignment method

This Sightmark boresighter uses a laser that loads directly into the chamber of your .223/5.56 rifle. You mount your scope and look through it while the laser dot shows where the barrel is actually pointing. No ammunition needed, no range trip required for initial zeroing. This speeds up the pre-range preparation significantly. Learn about our FFL transfer pricing if you're transferring a rifle through TacticCAL. The compact 7.4-inch design keeps it manageable in your shooting bag. Visit our gun store in Sunnyvale for our full catalog.

Frequently asked questions

How does a laser boresighter improve my zero process?

It shows your barrel's actual point of aim through your scope without firing. This gives you a starting point indoors, so your first live shots are much closer to your intended zero. You save ammunition and range time getting on paper.

Will this work with any .223 or 5.56 rifle?

Any rifle chambered in .223 REM or 5.56 NATO with a standard chamber will accept the boresighter. It loads like a round of ammunition, so compatibility is straightforward across AR-15s and bolt-action platforms alike.
