Rusan Picatinny rail – Steyr SBS, Classic, CLII, SM12 (SA) Detajli
Picatinny rail consists of slots with 5.23 mm spaces between one another, which means that it can be used across its entire length. It is simple to mount and interchangeable – if something is made for a Picatinny rail, it will fit regardless of the manufacturer or manufacturing date. It is affordable, resilient and reliable – this is why it so commonly used by professionals and military. Because of all its great qualities, Picatinny rail has been dominating the rail market in recent years.
Picatinny is a big step forward from the Weaver standard. Weaver has a few predesignated slots while Picatinny has slots all over its surface, allowing the device to be mounted wherever the user finds it fitting. Weaver’s slot is 3.8 mm wide, which is why ring mounts made for a Weaver rail will also fit on a Picatinny rail while ring mounts made specifically for a Picatinny rail will not fit on a Weaver rail. This is one of the main reasons why Picatinny is a far better mounting solution.
Rusan, a company from Croatia, is one of the manufacturers of Picatinny rails. They make mounts exclusively from steel and provide buyers with a wide selection of Picatinny rails for various rifles. They are made from high quality deep blue finish steel. Picatinny Rails include screws with appropriate thread for the corresponding rifle. Rusan covers 10 years of warranty for all its products.
About the rifle
Steyr Mannlicher, a renowned company that produces firearms, was founded in 1864 by Josef Werndl. It soon grew into a big company with great production capacity. In 1882, they faced a small crisis because of lack of large orders (they had supplied the European armies with breech-loading rifles – demand declined). This is when Werndl used the company’s production capacity to manufacture all sorts of products along with firearms: dynamos, electric motors, light bulbs, bicycles, cars, trucks. The company’s most active years were without a doubt during World War I when more than 4000 firearms were made daily by its 15.000 employees. The company’s name was changed to Steyr-Daimler-Puch AG in 1987.
It is important to know that SBS is not a rifle by itself, but an action (SBS stands for Safe Bolt System) which can be found in many different models of Steyr: Classic, CL II, SM 12, Pro Hunter, Pro Alaskan, Jagdmatch, Scout etc. SBS is a concept that deviates from the established principle of locking lugs at the rear of the bolt. Instead, two opposing lugs are formed at the front of the bolt. The safety catch has three positions: in the first position, the firearm is ready to fire and a red dot can be seen on the safety catch; in the second position, the user can see a white dot on the safety catch – the trigger is locked but the bolt can still be operated (loading, unloading); in the third position, where a white stripe and a white dot can be seen on the safety catch, both the trigger and the bolt are locked.
There is a difference between older (without SBS) and newer Steyr rifles (with SBS) as regards radiuses on the receiver (where holes are drilled for mounting purposes). The newer models are flatter (R35) than older models (R17.5, R15).
Steyr Mannlicher SM 12 is a bolt-action rifle that features Steyr’s SBS (Safe Bolt System). There are two locking lugs on each side of the bolt, 4 lugs altogether. The action operates very smoothly. Its bolt operates on a 90-degree lift and has a Sako-like extractor with a pivoting claw at the head (push-feed). It also features two emergency gas ports. SM 12 is equipped with Steyr’s Hand Cocking System which allows the user to manually cock the internal firing mechanism, which increases safety since it allows manual decocking of the firing pin. To load the firing pin and deactivate the safety, the user has to press it forward. To release it and engage safety by decompressing the spring, the user has to push it downward. The mechanism is very easy to operate and does not confuse the user, unlike some others. SM 12’s barrel is chambered for .243 Win., .308 Win., 7mm-08 Rem., 7×64, .270 Win., .30-06 Sprg., .25-06 Rem., 6.5×55 SE, 8×57 JS and 9.3×62. The magnum versions are chambered for 7mm Rem.
