Mercury sport STR Sport FC Black, caliber 6.5 Creedmoor

The repeating rifle Mercury STR Sport FC is a long-range rifle for precision shooters, with a special fore-end stock for F-Class. The rifle features a TLD system, designed for precise shots at the longest distances. The massive barrel has a diameter of 28 mm at the muzzle and a length of 710 mm. Interchangeable bolt handle The bolt is equipped with an interchangeable tactical bolt handle and an external magazine release lever, which is particularly suitable for the fast pace of competitions. Tactical stock The modular tactical stock is equipped with an aluminum chassis, a new fore-end, and a stock made from a high-strength Egal 55 alloy, machined on CNC machines. The cheek rest as well as the trigger travel are individually and stably adjustable with screws. The extra support attached to the underside of the buttstock fits precisely into the recess of a standard shooting rest, thus guaranteeing additional stability. The rigid chassis made of an aluminum alloy gives the STR Sport superior precision. The multi-radial barrel profile (MRR) When comparing a traditional barrel with a polygonal and the multi-radial, the latter is ideal for both traditional and full metal jacket bullets. In multi-radial barrels, two different radii alternate, giving the bullet geometrically positive support without overstressing it. In fact, the bullets are pressure-formed to follow the circumference and are not cut as in traditional barrels, which extends the lifespan of the barrel. Furthermore, there are no sharp corners like in other barrel systems where residues can accumulate, keeping the barrel cleaner and reducing wear. All tests conducted show: Multi-radial barrels shoot better and more precisely with conventional lead bullets and with full metal jacket bullets in calibers 7.62 mm (.308) and 6.5 mm (.264) than traditionally shaped ones. At standard pressure values, the exit velocity is higher than that of the conventional barrel—under certain circumstances by up to 12%. The bullet seals the bore better, preventing gas from escaping forward, which optimizes the effect of the driving energy. Additionally, friction between the bullet and barrel is minimized. The spatial arrangement has further improved due to the extremely tight production tolerances that must be adhered to in the manufacture of multi-radial barrels. The multi-radial barrel is ideally suited for the cold forging process. The consistency of the produced barrel profile is excellent, and the overall quality of the barrels has improved. The special barrel geometry of the barrel entry in multi-radial barrels allows for a more precise and continuous guidance of the bullet through the chamber neck and the bullet bore than is the case with conventional barrel systems—the bullet hits the barrel's rifling in the best way, reducing flight wear. Under the same conditions, less copper deposition occurs inside the multi-radial barrel, resulting in less cleaning being required. And when cleaning is necessary, it is easier than with conventional grooves. The user can further enhance the performance of the multi-radial barrel by simply applying abrasive paste during cleaning, without having to worry about ruining the barrel, as can be the case with traditional profiles. Robust safety The safety used locks both the trigger and the trigger sear. It is a very secure system, as the locking of the trigger sear is designed to be particularly robust. And when the trigger sear is locked, the firing pin is essentially locked as well. Theoretically, a safety that directly locks the firing pin is safer, but due to the small size of the components, these parts are often less durable.
