The Mosin Nagant rifle is one of the world's most popular rifles ever produced. Most shooters tend to complain about the heavy trigger pull. Many Mosin Nagants are purchased for nostalgic and collectible reasons, so some owners do not like permanent modifications and changes made to the rifle. There is a very simple and quick adjustment that can be done to lighten the trigger pull using aluminum foil. Place a single, small piece of foil between the leaf spring and receiver of the rifle. Test fire after each layer is placed to achieve desired pull.

Supplies Needed

  • Flathead Screwdriver
  • Aluminum Foil

Bottom Main Bolt

The bottom bolt that needs to be unscrewed is located in front of the magazine box.

Aluminum Foil Spring Spacer

The foil is secured between the trigger spring and the receiver. This limits the range of motion the trigger has, thus making it a lighter pull.

Steps to Lighten Trigger Pull

  1. Remove the receiver and barrel from the wooden stock using a flathead screwdriver. There are two main bolts to be removed. One is on top behind the cocking bolt, and the other is in front of the trigger guard.
  2. Locate the leaf trigger spring, and remove the bolt securing the spring to the receiver by unscrewing it.
  3. Cut a few half inch squares of aluminum foil, and cut a small hole in the middle of each square of foil.
  4. Align the hole in the foil with the hole with the hole for the bolt that secures the leaf spring to the receiver. The foil should lie between the spring and the receiver.
  5. Screw the main bolts by the magazine box and cocking bolt back in.
  6. Test the trigger pull while the rifle is unloaded by dry-firing a few times. Add or remove foil squares as needed to get the desired amount of trigger pull.

WARNING!

Never create a very light trigger pull. A light pull can cause accidental firing when the rifle receives an impact.

      I have been around a few triggers , is adding tin foil a standard gun smith practice for that particular rifle. I do not know and I do not own a nagant. Safety is my only concern.

      I wouldn't say it's a "standard gun smith practice." There aren't of any products that lessen the pull, so improvisation was the only choice. Dry-firing with a dummy round or empty shell about 750-1000 times will lessen the pull also.

      I've only lessened the pull with a few single pieces, so it's a little less heavy. I don't tinker with triggers on semi-autos. The foil just acts as a spacer. A washer or something would also work, but foil can be added and removed to get a more desired pull.

      I understand , be careful there is a reason why they aren't still in production - as far as I know.

      We have a Nagant, inherited from a great uncle. Someone tried unsuccessfully to sporterize it, and basically just chopped it. Sad. Still functions but looks like crap. Nice Hub.

      That's a shame. I'm not a fan of sporterizing older firearms, even if it is a Nagant that can be found just about everywhere. Thanks for the complement!

      It was probably done back in the 1930s or 40s, when Nagants were nothing special. Still a shame, could have done a good job on it.
