Rusan Picatinny rail - Marlin

Introduction

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 the 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 from steel and aluminium 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

Marlin model 1894 is a classic lever-action rifle. It features a unique lever-fire system which works on the principle of repeat-fire. The ejection port is located on the right side, upper and left sides are blocked. Its action has a flat-bottom surface but is round-shaped. On each side of the action surface, there are two mounting holes – that's four holes altogether. The action has a solid top receiver and metal surface with hammer block-safety. The length of the original rifle is 105 cm (later, many variations were released: 1894CBC, 1894CL, 1894 Cowboy, 1894CS, 1894FG, 1894M, 1894P, 1894PG, 1894S and 1894SS). 10–14 tubular magazine runs the entire length to the muzzle – Marlin has kept this feature for more than 110 years. It is chambered for: .218 Bee, .25-20 Win., .32-20 Win., .32 H&R Mag., .38 Special, .357 Mag., .41 Magnum., .44-40 Win., .44 Special, .44 Magnum and .45 Colt.

Marlin 336, chambered for .30-30 Win., .35 Rem. and .44 Magnum is one of the most popular lever-action rifles in the history. It is based on the former 1936 Sporting Rifle which was renamed to M36 in 1937 (Model 336 replaced M36 in 1948). M36 featured a coiled spring instead of a traditional leaf spring, making it one of the first lever-action rifles with such system in history. Marlin 336 has a 20 or 24-inch barrel and a six cartridge tubular magazine. It ejects cartridges on the right side of the receiver and has a flat top. The action, which has two mounting holes on each mounting surface, is round-shaped with a flat bottom. Marlin released many versions of this rifle, based on the original 336 model: 336A, 336ADL, 336C, 336CC, 336 Cowboy, 336CS, 336ER, 336LTS, 336M, 336SS, 336T and 336W.

Marlin 444 CL is a lever-action centerfire rifle chambered for .444 Marlin caliber. It was introduced in 1965. The ejection port is located on the right side, upper and left side are blocked. Action, which is round-shaped, has a solid top receiver, metal surface, and hammer-block safety. There are two holes on each of the mounting surface. 444 CL is equipped with microgrooves on the top end of the barrel. Its barrel is 61 cm long. The tubular magazine provides space for 5 cartridges. 444 was succeeded by 444S and 444SS.

Mounting instructions

Remove all the stains (grease, oil etc.) from the rifle's receiver with a cleaning fluid (acetone). Once the surface is clean and dry, check whether the screws match the rail and the holes on the receiver. Make sure that the Picatinny rail is compatible with the rifle by inspecting the mounting holes on both. Before mounting the rail permanently, apply a minimal amount of thread-locking fluid 278 or 648 on screws and contact surfaces. Be careful not to get the fluid in or near the mounting holes. Carefully clean the remaining excess fluid around the rail with a cleaning fluid. Using a torque driver, screw the screws appropriately (up to 2.2 Nm) – do not overtighten.
