low number 1903 conversion to 22 rim fire

[Mike Haas]

A few years ago I bought one of the CMP low numbered barreled receivers for $100. I received a SA receiver (without finish) in the late 590xxx serial range with a burned-out SA 1921 barrel. I put this barreled receiver aside for a few years until I could find a way to salvage this project. Later a man from NC on another forum was selling a 1903 barrel that he had installed a 22 rf liner with the rear extension to fit the M2 bolt. I bought it as it was a really good buy and I had a M2 bolt complete. Not difficult to install the 03 barrel, I also had an old Lyman 438 scope to use too. First target at the pistol range looks good with standard 22 rf cartridges.

RCS..Your .22Cal Barrel liner is from the Numrich Arms 1903/1903-A3 .22 Conversion kits made in the early 1950's. Numrich Arms only made "about" 1500 of the kits. Bropheys Book mentions the Kits.

The original kits contained the barrel insert (made by Marlin) - a modified 1903-A3 Trigger Guard - a !903 - M2 Bolt and a Magazine made by Harrington & Richardson. They also incuded a special wrench for installation/removal of the barrel insert.

Any of the above parts are very difficult to find seperatly..even harder to find are complete kits..in the original boxes..with instructions...

I do have all the above...which includes the original outter shipping sleeve/cardbox box sent to the original buyer in Arizona...

Somewhere in my future I see converting my Numerich Kit into a reasonably nice 1903 Remington (Non Greek).
