Holosun LS321G&IR Co-axial Visible Green & IR Laser and IR Illuminater Aiming Device with Picatinny QD Mount
The Holosun LS321G & IR is a compact, all-in-one laser aiming unit built for serious rifle setups, especially if you’re running night vision. It packs a visible green laser for daytime use, a co-axial IR laser for NV aiming, and an onboard IR illuminator so you’ve got your own light source when things get dark. Everything is aligned together for easy zeroing, and the quick-detach Picatinny mount makes it easy to install or remove without messing up your setup. Built from tough 7075 aluminum with waterproofing and a pressure switch included, it’s basically a full-featured laser + illuminator package in one rugged block
