I used a low number 1903 receiver with a shoot out barrel, had a 22 rim fire liner installed with an extension at the end to fit the Springfield M2 rim fire bolt. Better to use the M2 bolt that has the adjustment for headspace. Some use the drill rifle receivers and actions or they use the 1903A3 to make 1903A4 snipers in 22 rim fire. These rifles can be quite accurate.
