The Mosin Nagant is known to be a simple and effective rifle. With a bit of work, the rifle's accuracy will be increased without any aftermarket modifications or machining. "Accurizing" is a set of processes that increase the accuracy of a firearm. A few things can be done to accurize the rifle. Sanding the inner stock will allow the barrel to free float while cleaning and oiling the trigger assembly will decrease trigger pull. Attaching a bayonet can improve accuracy and help balance the rifle.

Things you need
- Flathead screwdriver
- Firearm solvent cleaner
- Firearm oil
- Dollar bill
Unload the rifle's magazine box and chamber. Move the bolt into the upward de-cocked position and slide the bolt fully back.
Hold the trigger down. This allows the bolt to slide out of the receiver. Pull the bolt back until it is free of the receiver. Release the trigger.
Remove the rings that hold the stock and hand guard to the barrel. Pressure must be applied to the springs on the stock under each ring before the rings will be free to move.
Remove the bolt located on top of the stock using a flathead screwdriver. This bolt secures the stock to the receiver.
Unscrew the bolt located below the receiver. This bolt secures the magazine box to the stock.
Pull the magazine box carefully out of the stock and set it aside.
Fold a dollar bill in half. Slightly lift the barrel out of the stock. Place the dollar bill halfway under the barrel but above the stock.
Let the barrel fall into the stock. The bill should be sticking out on both sides of the rifle, between the barrel and the stock.
Start at the front of the stock and drag the dollar bill evenly from the tip of the stock to the rear sight. If the bill snags on the way down, the stock needs to be sanded. On that spot use coarse sandpaper and finish with a fine grit sandpaper. Create just enough space for the bill to slide smoothly. Do not overly sand a certain area.
Reassemble the magazine box and receiver back onto the stock. Keep the bill where it is. Slide the bill, as before, and see whether it snags. Disassemble the rifle and sand as needed.
Drip a small amount of gun oil onto the tip of the barrel.
Slide the bayonet onto the tip of the barrel. The slot in the base of the bayonet must align with the front sight post. A few gentle taps from a hammer may help.
Depress the small button once the bayonet is as far onto the barrel as it can go.
Tap the area of the bayonet near the button counterclockwise. Continue to tap until the bayonet cannot rotate any further.
Release the small button. Make sure the button completely clears the sight post.
Unscrew the bolt holding the spring onto the receiver. The spring is between the trigger and receiver. It is only accessible if the receiver has been removed from the stock.
Remove grit from the spring and from the trigger assembly.
Oil the spring and the parts of the trigger assembly that contact the spring. The less friction, the smoother the trigger will pull.
Screw the spring back onto the receiver.
Drop the receiver back into the stock.
