Mounting a scope on to your Mosin Nagant may not always be as simple as mounting one on to other types of commercial rifles. The Mosin Nagant was originally intended to be a soldier’s rifle for purely long range engagements where open sights would be used. These rifles were originally equipped with what is known as a bent bolt which is something that can still be discovered on many modern hunting rifles, unlike the regular Mosin Nagant (which is now known to utilize a straight bolt). The design of straight bolt was used on the Mosin Nagant’s to allow a soldier a relatively quick rate of fire. The only downside to this straight bolt is that it will not work with modern receiver mounted scopes.
In order to overcome this problematic straight bolt, as a shooter you have two options available to you. You can either manually bend the bolt handle or use what is known as a scout type scope mount.
