ORSIS T-5000 supplied with a single-point cut rifled stainless steel barrel. The internal geometry of the barrel is optimized for the use of standard factory ammunition. All barrels are manufactured with a tolerance on the rifling of 0.0025 mm. Exclusive formula of the barrel’s interior geometry (number of grooves, twist, barrel length and angle of bullet entrance) is not used by anyone else in the world. Intentionally for the production of ORSIS barrels the technology of the trellis hook manufacturing was changed (made of hard metal alloy), which allowed for the precise final characteristics of the bore. After the rifling process, the bore and barrel throat are polished on special finishing machine. These technical solutions allows ORSIS T-5000 to achieve highest possible accuracy.
The contour of the barrel - Match, barrel length - 24 inches (609.6 mm), muzzle diameter - 23 mm. There are flutes along the barrel for rigidity and reduction of the cooling time. The rifle is equipped with the original trigger, developed in our company’s own design office. The monocoque hull of the trigger is made of hardened stainless steel, internal components - of “scalpel” steel, which underwent special thermal and chemical treatment, the lid is made from a titanium alloy (used in the aerospace industry). The construction of the mechanism is isolated from external influences. The lid is secured with four standard screws, which allow, if necessary, to service, repair and replace the internal components machinery, even in the toughest conditions. The simplicity of design, a large range of adjustments for the backlash and trigger firing load, ability to set the trigger of any geometry, make the ORSIS trigger something that the company is really proud of.
Modification of the trigger mechanism:
The bolt group, of ORSIS T-5000 rifle has a strength margin of more than 30% of test pressure, which greatly increases the operating safety of the weapon. The components of the bolt group are made of stainless steel and are subjected to heat treatment to obtain the desired characteristics of hardness and high strength using electrical discharge machining, which results in an ideal internal geometry. This provides a nearly perfect positioning of bolt on locking lugs, which affects the precise running of the striker and, eventually, leads to very accurate and stable shooting.
The stock of the rifle is made of duralumin alloy D16T. The application of this "aeronautic" material allowed obtaining unprecedentedly high rigidity.
The stock is equipped with an adjustable cheek piece and back plate and a unique folding mechanism with a mechanical lock in the folded position, made of steel. Cheek piece forend hunguard and ergonomic pistol grip milled from caprolon (high-strength polymer). Recoil lug is pressed to abutment surface with a special screw that has a positive effect on the stability of firing.
Design features of the stock provide the correct distribution of the mass movement of the rifle during recoil (balance), which reduces recoil effect even in large calibers and allows a shooter to see the target at the moment and after he or she takes a shot. This unique feature makes quick sight shooting possible, significantly reducing the time to return the aim at a target after the shot.
The rifle is equipped with a Picatinny rail for an optic sight. Metal parts of the rifle can be painted in different colors according to customer’s order with Cerakote coating.
The rifle is equipped with an ORSIS four-chambered muzzle brake, which reduces recoil up to 50%. Rifle weight - from 5.6 to 5.8 kg.
Detachable magazine for 5/10 rounds. The rifle can be made in the left-hand and right-hand operation versions.
The standard version includes glass-bedding.
