i see them on gunbroker, any of the parts suppliers will have them from time to time for cheap.
Edit i might add a bar on the front of the tube or possibly the bushing depending on materials used to use the bolt for the pistol grip as well for additional stability. Might just eliminate that wobble you feel when changing mags. Of course a bushing attached to the tube would do the same thing with the additional benifit of possibly finding something that will be able to be used as a lube point.. (think driveshaft coupler on a heavy truck)
I could also be over complicating this as i tend to do LOL
