Product Description
sightmark The Sightmark Laser Boresight provides the most convenient and accurate method for sighting in rifles of all types. Simply chamber the boresight like a regular bullet and a laser dot will show exactly where the rifle is aiming; it's easy to sight in any scope without firing a single shot. Live fire is only needed to fine tune the weapon being sighted in order to compensate for inconsistencies, such as bullet drop due to distance. Perfect for hunters, competitive shooters and law enforcement, the Sightmark laser boresight is sure to take the frustration out of sighting in almost any gun. It's easy to use and will quickly save both time and money by avoiding prolonged live fire tests at the range; use the extra ammo for honing those shooting skills and for the hunt. A lightweight carrying pouch protects the laser for convenient use in the field.
Size .40 S&W

Comments about Sightmark .40 SW In-Chamber Laser Boresight:

Bought the device to help me practice with sight characteristics of a new S&W M&P Pro 40. The problem is manufacturing the device to the specifications required for the chamber. If you install the device you will find that it is never the same each time. The laser will point left, right, up, down, depending on how the device was rotated when chambered.
Good idea, just not easy to implement apparently.
