I owned a couple of them many years ago. To me, the most difficult part of the conversion looked to be the milling of the action to feed cartridges from what appeared to be a Model 70 Winchester liner box. If I was doing the conversion now, I would use one of the wonderfully designed .22 Hornet Anschutz clips and alter the M2 trigger guard to retain it. One of those rifles, that Buckstix now owns, has the original Springfield stock with a beautifully inletted G&H cheekpiece. The other has a newly made G%H stock.
