Ruger 10/22 10-22 Single Shot Adapter BX1 BX-1

thingiverse

This is a single-shot adapter for any Ruger 10/22 or Rimfire Target rifle that uses BX-1 magazines. If you are training someone (including youths) and want them to handle only one bullet at a time, this is easier/faster than loading a single bullet into a magazine. Single-shot loading is also required at some rimfire target match competitions. I made this one more precise than what you typically find because of my own needs -- I do not always use round-nose or even standard hollow-point bullets, but flat nose and wad-cutters. This has no problem feeding those into my Ruger Rimfire Target rifle even though they won't feed properly out of a normal BX-1 magazine.
