Anyone know how to tell the difference between the manufacturers of the USGI M261 adaptors? I know they were made by the NavAir facility for the US Navy, SACO, OK under US Armament contract, and Maremont (Later SACO Defense).
Any ideas??? |

You might try asking the folks at Compass Lake.
They have been using the M261 in their .22lr match rifles forever. |
