New 5mw green laser sight. This laser has an interchangeable adapter to let you have an over the barrel laser sight, and exchange it for another adapter to be a bore sight laser. We also have an adapter to be a rifle bore sight. Our rifle bore barrels are smaller than the usual smooth bore. The 2033G comes with the over the barrel adapter. The smooth and rifle bore adapters are purchased separately or as another kit. You can purchase the complete kit (K2033G), and it will contain all three adapters.
