The Omega Z5 features Thompson/Center’s pivoting breech lever, sealing the action against rain and snow for reliable ignition in harsh weather. The Speed-Breech plug removes with a simple 90-degree twist, making cleanup faster after a day on the range or in the field.
At 14 inches, the length of pull suits most adult shooters, while molded checkering and an integral recoil pad improve control and comfort during extended shooting sessions. Integral sling swivels let you attach a sling without additional hardware.
The 28-inch carbon-steel barrel wears a deep blued finish that complements the blued receiver. T/C’s QLA muzzle treatment slightly enlarges the bore at the crown, guiding sabots and conicals straight into the rifling for easier, more consistent loading.
Introduced in 2006 and discontinued around 2012, the Omega Z5 represents a later evolution of the popular Omega line, appreciated for its straightforward inline system, solid accuracy, and field-ready durability.
