Sniper rifle “Unique Alpine TPG-1”

Unique Alpine TPG-1 sniper rifle

The Unique Alpine TPG-1 sniper rifle (Taktisches Präzisions Gewehr - tactical precision rifle) was developed in Austria by the Unique Alpine company.

The rifle has a modular design that allows you to easily change barrels and used cartridges (calibers).

During the development of the new rifle, special attention was paid to modulating the design of the rifle in order to create a highly uniform weapon that will allow the shooter to adapt the rifle to his individual anatomical features. Also, the modular design of the Unique Alpine TPG-1 allows the shooter to quickly customize the rifle to suit the specific situation.

Other advantages of the Unique Alpine TPG-1 modulation system are the unlimited interchangeability of various parts and structural units.

This is reflected in a significant reduction in maintenance costs, since labor costs are much lower compared to conventional weapons.

The Unique Alpine TPG-1 sniper rifle is built on the basis of a proprietary receiver and bolt group.

The bolt is longitudinally sliding, rotating, locked with three lugs.

The firing mechanism has a fully adjustable trigger.

The barrels are quick-change, fixed in the receiver using one transverse screw. To change the caliber of a rifle, you need to replace the barrel and bolt, and for some calibers, also the magazine.

Chambered for 7.62x51 mm. the company additionally offered a shortened barrel with an integral muffler.

The steel receiver is rigidly attached to an aluminum block, to which a detachable stock with a pistol grip and fore-end are in turn attached.

The rifle is not equipped with open sights as standard. In this case, optical sights are mounted on a Picatinny rail type guide mounted on the receiver.

The stock is plastic, with an adjustable buttplate and butt cheek.

A retractable adjustable support is installed at the bottom of the butt.

The forend has a mount for a bipod.

The Unique Alpine TPG-1 sniper rifle was offered as both a sporting weapon and a police sniper rifle. With specially selected cartridges, the rifle exhibits an accuracy of about 0.5 minutes of arc (MOA).

The use and regular use of selected, high-quality auxiliary materials guarantees long service life of the rifle without loss of quality and accuracy when shooting.

The enormous capabilities of the Unique Alpine TPG-1 are achieved thanks to a previously unused combination of an ergonomic approach, the principle of a modular rifle design and new technologies:

Solid shutter made of high-quality heat-treated steel: - 3 locking lugs with a practical 60-degree opening angle. — 4 gas outlets. — minimal vibrations for the highest shooting accuracy.

Unique Alpine TPG-1 on Bipod
Removable Adjustable Handle: - Anatomically designed handle with thumb hole and non-slip technology for a secure grip. — fully adjustable part of the handle with a recess for the cheek. Thumb Position Adjustment: - Fully adjustable cheek and butt grip section with pointer index and click adjustment for greater precision. — “breathable” plastic with a non-slip surface. — unified slope of the handle with the ability to operate with one hand and setting the shooting accuracy.

Reliable fixation mechanisms: - stable fixation of the arsonist, which pulls back the striker and blocks it. — additional fixation of the trigger mechanism can be installed.

Massive, movable, highly accurate in shooting barrel, grooved: - stabilized level of barrel vibration. — quick barrel change for greater caliber change possibilities. - Inserted into the rifle using a 50mm bushing for greater accuracy and safety.

Unique Alpine TPG-1 in a case with a set of accessories
Installed sighting chassis system: - defined flat surface to prevent deformation. - Vibration reduction system made of synthetic polymers creates a permanent connection between the frame and the rifle and reduces vibration during shooting. — a system of fastening bolts with compression springs guarantees a constant connection between the body and the frame, thanks to equal tension.

Faster and easier maintenance: - modular design and interchangeability of components significantly reduces the owner’s costs when purchasing and repairing a rifle. — routine maintenance of the rifle does not require special skills. — the rifle is easy to clean thanks to the use of anti-corrosion materials. — use of unified stabilizing adapters.

Relief ridges for fingers: - reliable and comfortable grip under any conditions. — made of breathable synthetic materials with a non-slip surface for greater comfort. - Resistant to oils and cleaning agents.

The frame design is entirely made of aluminum: - not affected by climatic conditions. - high-quality aluminum alloy, the same as in the housing, gives the same expansion coefficient, which prevents deformation and guarantees high efficiency. — a unified and additionally installed system adapter for the use of night vision devices.

Valve made from "F 53" aluminum billet: - special high quality aluminum with a tensile strength of 530 newtons per mm. - low line of sight to minimize aiming error. — sight locking mechanism for greater accuracy. — the installed rail makes it easy and simple to install the optical sight.

ORSIS SE Alpine

The rifle is made with two front lugs.

The rifle with manual reloading is manufactured for extreme conditions of mountain hunting in specialized hunting calibers with a flat trajectory. The metal parts of the rifle are made of steel with enhanced stainless properties, with a black corrosion-resistant Cerakote - Black Graphite coating. Detachable plastic magazine for 3 standard cartridges.

The model is equipped with a free-floating stainless steel ORSIS Barrel contour - Alpine , muzzle diameter 18 mm, barrel length 609.6 mm (24 inches).

ORSIS muzzle brake-compensator , model 003. The barrel has fullers for additional rigidity and reduced cooling time.

Stock with cheek adjustments. The standard design includes glass bedding¹ and pillar bedding².

ORSIS Alpine rifle stock models

• A1 (cheek adjustment),
• A2 (cheek adjustment),
• M3 (cheek adjustment).

All stocks have lower swivels for attaching a sling and bipod. The stock is made of weapon grade laminate. Samples of coatings It is possible to manufacture the ORSIS Alpine for left-handed and right-handed people.

Trigger

The rifle is equipped with an original trigger mechanism developed in the company's own design bureau. The design of the mechanism is isolated from external influences.

• Standard - force 750 g. +/- 150 g.

The rifle is equipped with a Picatinny rail (bases) for mounting an optical sight.

The rifle comes in original packaging.

Trigger modifications:

• Standard - allows you to adjust free play and force from 750-850 g.

Most ORSIS produced have an accuracy of no more than 0.5 MOA.

¹ Glass bedding

– making a “bed” for the bolt group from an epoxy compound with filler (aluminum or steel). With the help of Glass bedding, a larger area of ​​contact between the bolt group and the stock is achieved and, as a result, less specific pressure on the stock; absence of micro-displacements of the bolt group relative to the stock when fired; no deformation when tightening screws; lack of response to changes in atmospheric conditions, which is a fairly important factor in increasing the accuracy of the rifle.

² Pillar bedding

– insertion of bushings (large in size to reduce the specific pressure on the stock) into the places where the bolts of the bolt group pass through the stock.

Hunting rifles Orsis model “Alpine SE”

Every hunter knows that the choice of weapon is paramount in this matter. First of all, it is necessary to determine the required technical characteristics and features of various manufacturers and types of weapons, on which the final cost will depend. Approach to purchasing an Orsis hunting rifle model “Alpine SE”

it is necessary with all responsibility, carefully selecting the right model.

The most common among hunters are smooth-bore rifles, which do not have a long firing range like rifled carbines, but have other advantages. To purchase them, you only need a weapons permit; you can use ammunition such as shot, buckshot or bullet. Rifled carbines allow you to hunt large animals due to the possibility of using large-caliber cartridges; they can also be used to conduct targeted shooting over long distances.

Smoothbore guns can be divided into several types:

• single-barreled (single-shot and multi-shot models, with the possibility of manual or automatic reloading);
• double-barreled (models with horizontal and vertical barrels).

Orsis hunting weapon

can be classified as follows:
