This long, straight bolt points directly up. When the shooter rotates the bolt to load or puts another round in the chamber the bolt rotates 90 degrees. The second obstacle is the straight bolt. There isn’t any method to drill and tap the top of the receiver that would succeed. The first obstacle in mounting an optic to the Mosin Nagant is a lack of an easy-to-use mount. Times have changed though, and optics are often considered standard for any centerfire rifle. Optics weren’t really very good or used much at the time. Now attaching an optic to the Mosin Nagant is not a simple snap on affair, while most of us are spoiled with flat top AR 15s, the Mosin suffers from being made in the later 1800s. The open sights on the Mosin Nagant are one of the weapon’s weaknesses, they are difficult to see, hard to use at long ranges, and do not take advantage of the weapon’s long barrel, and powerful cartridge. Since the advent of the Mosin Nagant repeating rifle, there have literally been more than a hundred years of refinement in sighting options for firearms. An optic allows shooters to extend the effective range of their weapon, enjoy shooting the firearm a bit more, and being generally way more accurate with an optic than without. As much as purists proclaim, “Nyet, the rifle is fine,” the addition of an optic can improve the weapon’s performance. Others may want to customize their rifle a bit and improve its performance. Some people buy the rifle and are perfectly happy with its performance. These rifles are extremely cheap, they fire a powerful round that is also cheap, and they are a blast to shoot. The Mosin Nagant rifle is an extremely popular rifle in the United States, regardless of the fact it is a Russian design made before the First World War.
