| High Efficiency Gas Ram | |
| Gentle Recoil |
This rifle is powered by our latest generation H.E. (high efficiency) Gas Ram System which improves consistency and reliability. Using new piston crown material our specially designed Zephyr grooves are no longer in the piston crown but now machined into the end-wall of the compression chamber.
The Evolution is available with a choice of stocks: An attractive right or left handed Walnut stock, a right-handed Walnut Thumbhole stock or a sturdy ambidextrous Beech stock. The Walnut stocks have a checkered pistol grip and forearm - the Beech stock is checkered. All stocks are fitted with a ventilated recoil pad.
This rifle was designed to be the entry level model of the Theoben lineup. But they haven't scrimped on quality or taken shortcuts. Everything is as you would expect of a Theoben; high quality parts and materials meaning very low maintenance and a H.E. system that results in almost no recoil, making it very easy to shoot.
The Evolution uses the industry standard 11mm mounts allowing you to select your favorite mount and scope combination.
This rifle has been quoted by well known shooter Terry Doe as being "one of the fittest sporters money can buy" thanks to the ambidextrous beech stock with its checkered pistol grip and forend and an oiled finish. A satin black finished action and barrel rather than the hi-gloss black.
The Evolution rifle is fitted with the fully adjustable Evolution Trigger with its automatic safety catch.
