DaveT Posted September 11, 2020 Report Share Posted September 11, 2020 Gents Short of having to buy the specific YHM wrench for a one-off removal ... any ideas on how to loosen the jam nut on a YHM handguard? I have a DPMS armourers wrench but there does not seem to be anything that fits the jam nut. Thanks in advance. Ps.... if anyone has YHM wrench thats unwanted then I will buy it rather than faff around. Quote Link to comment Share on other sites More sharing options...
