01 Finest Barrels
Stainless steel match barrels are produced from 30-inch (70cm) bars drilled by an extra-long two-lip drill (like a foil blade). This hole is then machined by another tool, a special borer cutter. Then comes the finish made with a mandrel coated with diamond powder to obtain polishing and a perfect diameter. The tube thus prepared is then rifled with a tungsten carbide button, chosen for the desired caliber, drawn in force inside the barrel by a hydraulic machine.
The bench where this is done is equipped with a mother screw and a pantograph to finely adjust the desired rifling. The barrel is then annealed in an oven in order to remove the stresses created by the process. Then it’s straightened with the press and a laser followed by the outer definition of the barrel to get the desired profile.
Our barrel production process is long and complex, but it is the only one that guarantees an excellent accuracy for match rifles. That’s why Unique rejects the option of cold-hammered barrels.
Many manufacturers throughout the world practice the rifling of their barrels by cold hammering. This process has the advantage of a very low cost and an extremely rapid manufacturing, Such barrels cannot be described as ‘match’ because of the tensions created by hammering.
02 HQ Materials
In order to carry out the chambering of the Unique barrels, a floating mandrel machine is used with a roughing tool for the first pass. The body finish of the case and the neck of the case are obtained with another special finishing tool. The free-bore is machined in stride, according to the request of the customer if he wishes that the bullet comes in contact with the grooves or not. The headspace adjustment is custom-made according to the use of the weapon.
The materials used for manufacturing are selected for their qualities: the barrels are made of stainless steel, the locking ring (barrel nut) and the cylinder head are made of hardened high-strength steel, the receiver is machined from aviation grade Ergal (zinc alloy, magnesium, copper, aluminum), and the central support beam is Duralinium (aluminum alloy, copper, magnesium, manganese). All other parts are machined Duralinium or black synthetic material.
03 Hand Fit & Finish
Bolts, receivers, beams and other parts as wall as fitting & mounting of the RS1 are all made in the French Unique factories. Each piece receives a suitable surface treatment, sandblasting, micro-blasting, polishing, anodic oxidation, blueing, painting or Cerakoting. The receiver is anodized, the barrel is matt black blued, and the beam receives a matt black paint.
The original design, intends to produce the most accurate Bolt Action Rifles. The Floating barrel is easily removable without special tools and maintained with no complication nor any contact with the receiver, for an optimal vibration. Ability to quickly change calibers with interchangeable barrels, bolts and magazines from standard calibers (7.08 Rem, .308 Win.) to long calibers (.30-06, 6.5 Creedmoor, -.284, .30-284) or magnum (.300 WM, .338 WM, .338 LM), by keeping the same beam, optics, stock and receiver.
Our decades lasting and improved experience in firearms manufacturing, the techniques we use for barrels, actions, blots and receivers, the superior quality of materials we select, the fine hand fit & finish we give to each piece of each rifle we produce, the fully modular capability, and the possibility we give to every shooter to fully customize his own rifle makes of the Unique-RS1 an out standing precision long range shooting rifle with an unquestionable accuracy, durability and reliability.
