Use the Polishing Kit to remove machining marks and burrs on metal surfaces that interact with one another. While your at it we highly recommend polishing the internal components with the M*CARBO Firearm Polishing Kit!

It's likely the crown could use some finishing on the muzzle of the barrel on your Mosin Nagant. Remove any burrs on the muzzle of the barrel of your Mosin Nagant with our Brass 45 degree Lapping Tool. We highly recommend lapping the crown of the muzzle on the Mosin with the Muzzle Lapping Kit!

Ok, this trigger kit works as advertised. We completed the install on my brother in laws Mosin and what an improvement. The side to side play was greatly reduced and the pull feels like a new trigger on a modern rifle. I can't wait to get mine done. Thanks guys.

Pros:
Cons:
kit is for a worn out old mosin to repair he worn / used areas .. BUT on a like / new it is useless as it does nothing or can not fit.. plus the h.d. firing pin spring if it replaces a working one [ shorter / less pressure ] it will increase trigger pressure .. note adjust the firing pin flush as normal then back off 1/2 turn [ down ] and the trigger spring pressure will lessen and be shorter just check the pin extension out of the pin hole in the bolt head .. a heavy spring is for the hard mil-spec. primers and the cold red winters to '' work '' .. a set of lighter pin springs might be a better way for a better trigger pull .as the spring puts pressure on the sear and area you are to smooth out .. so a increase spring is the wrong direction .that way one could try asst. weights till the trigger was as light as they want but still strike the primers well enough with out backing the pin off ..the new trigger return spring keeps slipping off after 5 pulls of the trigger ..

This kit is by far the best thing for a standard Mosin. The trigger shims wouldn’t fit beside my Huber trigger, but I have no doubt they will work with a stock trigger. The spring went in without a hitch with the supplied string. The striker spring is the best on the market - I had a Wolff spring in this particular gun, and what a difference!
