Improve the function and safety of your Mosin Nagant with this kit.

Each kit consists of 1 each of the following:

1 - Mosin Nagant Slack Spring
               Get rid of that loose trigger feel associated with most Mosin Nagants. Installs on trigger pin for simple installation. Spring uses less than 1/2 pound of force to hold trigger in forward position. Spring was designed to provide the proper amount of forward pressure on the trigger then tested for reliability and safety. The result is no slack or looseness for a much improved trigger pull and better accuracy. Springs will work on all Mosin Nagants including Finnish Models. All springs are guaranteed  for life not to break under normal usage. Springs will be replaced free of charge. Use only ORIGINAL Slack Springs, accept no substitutes!

1 - Mosin Nagant SS Firing PinMain Spring (heavy load spring, preferred for our rifles and ammo)
               Each Spring is made using high quality stainless steel then heat set and load tested to insure each spring provides consistant performance. Each spring is made using high quality stainless steel then heat set and load tested to insure each spring provides consistent performance. Passivated for Maximum Corrosion Resistance. Load rate is less than the original springs load rate. Improves bolt cycling and safety engagement. Will work on all Mosin Nagants including the Finnish models.

1 - Mosin Nagant Front Post Extension
               These extensions are made from black polyethylene. The inner diameter should be of the correct size to fit snug on most Mosin Nagants with the round post style sight. The outer diameter is only .035 larger than the original post. Allowing little change in the sight picture. With an extension installed it can be cut to the desired length to lower impact. 1/8" longer than original post is a good place to start. You can always cut it shorter if it's too long. There is enough material in each kit to extend at least 4 posts.

Developed, Tested and Manufactured in the U.S.A. Authentic C&R Surplus Spring product!
