Description Designed to be the perfect zeroing tool, the Sightmark .380 ACP Pistol Boresight chambers in your firearm, allowing shooters to sight-in more accurately than with a muzzle attached boresight. Compact and lightweight, this in-chamber boresight’s brass construction improves durability, as well as chambering and ejection. The laser has a battery life of 1 hour on 2x AG5 batteries and allows firearms to be zeroed from 15-100 yards.
