The Targetmaster 1” scopes have been designed and are built to deliver consistent and repeatable accuracy shot after shot. Available in 5 models these scopes are built upon a one piece solid aircraft grade aluminium 1” tube for optimal strength and durability. All scopes utilize 100% water proof, dust proof and foog proof construction and are purged with Nitrogen gas to prevent an internal fogging and corrosion. Fully multicoated lenses offer a sharp and clear image. All elevation and windage turrets incorporate a ¼ MOA click adjustment with lockable zero-retention rings.
