Our supplier that has been the source for our bolt bodies for many years has decided to unexpectedly nearly double the price to purchase these components, We are not sure if this is because the supply locally is dwindling or due to possible changes in imports. It is because of this increase that RSI is forced to raise our price on our modified bolt bodies. The new selling price will be 80.00 dollars for the regular bolt body and 65.00 for blems. You can still send in your bolt body to be modified by us at the same price of 50.00.
