A new heavy hitting scope is on the market from Zero Compromise Optic. The company is relatively new being founded in 2018 but is gaining traction around the world amongst sporting shooters and hunters.

They currently offer three high end optics, the ZC420 4-20×50, ZC527 5-27×56 and the newly released ZCO840 8-40×56. Don’t be surprised by the price tag on these as the optics are competing against other high-end manufactures such as Nightforce and Schmidt & Bender and feature a very robust construction and high light transmission.

The company does offer a good selection of reticles to suit different users preferences.
