Just a note on using M1922 barrels for the conversion. There are two different types. The earlier one are made from a dedicated M1922 billet so they will have the full length of the standard M1903. The later one's are shorter as SA started to use 1903 billets making the barrels about 1/2 inch shorter. That's if you need to put a bayonet on the rifle. They are just a lot of fun to shoot and cheaper than an original M1922. Last one on the CMPicon auction site was up to over $2100.
