Up for sale is THE ORIGINAL Mosin Nagant Galvanized 12 piece shim set  for the M38, M44, and 91/30 rifles. They are also great for PU, PE, and PEM snipers. These shims will also fit Chinese Type 53 carbines and Finnish Mosin's. 

These shims can be used to tune barrel harmonics by floating the barrel which increases accuracy. By tuning your rifle your "groups" will become tighter. "Accurizing" procedures were used by Finnish armorers on captured Russian rifles and by Russian snipers during WW2.  During combat soldiers would create shims from any galvanized metal they could acquire. 

This auction is for 12 laser cut 26 gauge galvanized shims.

There is a seller on here who purchased my shims and used them as templates to make his own out of aluminum.  I put a lot of time and research into this kit and the process, others took the short cut.  

This kit contains shims ONLY and is intended to supplement other kits.  I can answer any questions upon request. Soviet flag not included.
