A gentleman by the name of Brian Rau, has been very successful in putting together parts consisting of shims of high grade materials, cork gaskets, and canvas barrel wraps.
These kits will improve the accuracy of your Mosin Nagants. Sometimes by a lot. All depending on barrel condition etc.
I personally have seen just how great of a difference they can make.
The instructions are excellent.
He researched how the Finns and Russians accurized Mosin Nagants during the war, and simply provided the same instructions and materials in ready made shims.
He will be releasing kits for Mauser rifles soon. I have seen the instructions already, and I am very impressed with the details in the instructions.
I have several Swedish Mausers, and other Mausers. They all are very accurate.
Not all are accurate, and will require refitting. It's not a complicated job. However you do need to know what you are doing.
That's where Brian's kits come in. HE has done all the research and work in cutting the shims out, as well as gathering all the correct information.
