Mounting a scope on to your Mosin Nagant may not always be as simple as installing one on to other types of commercial rifles. The Mosin Nagant was initially intended to be a soldier’s rifle for purely long range engagements where open sights would be used. These rifles were initially 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.
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.
