Tren, no, this sure cycle item is simply a replacement of the spring housing tube and spring itself which is in the stock; it is made of stainless steel and resistant to corrosion. I completely disassembled my M1 last night and the stock tube and spring are in fine shape, just a little dirty. My plan at this point is to clean it up and use Flitz to polish the inside of the tube as a final step, then very lightly oil with synthetic oil and reassemble.
