minnesota1 Posted April 3, 2020 Share Posted April 3, 2020 I picked up a couple of Miculek comps. They come with a Jam nut. I never used them before. I have some JP double crush washers. What are your preferences? Any downsides to using a crush washer vs the jam nut or vice versa? Thanks for your input. Link to comment Share on other sites More sharing options...
HRider Posted April 5, 2020 Share Posted April 5, 2020 I like jam nuts. I like to remove the comp and clean the crown periodically, with a jam nut, I can use witness marks to put the comp and nut back in the same place with the same tension. Jam nuts are not as pretty as a crush washer or a timed comp. Hurley Link to comment Share on other sites More sharing options...
HCH Posted April 5, 2020 Share Posted April 5, 2020 I’ve done both. I can’t really say I like one better than the other. Link to comment Share on other sites More sharing options...
rovpilot337 Posted April 6, 2020 Share Posted April 6, 2020 I prefer jam nuts. They are easier for indexing the comp and also reusable if you need to remove the comp for some reason. Just my opinion though. Link to comment Share on other sites More sharing options...
usmc1974 Posted April 6, 2020 Share Posted April 6, 2020 I don't like either, so I fit the comp to the rifle without either. Link to comment Share on other sites More sharing options...
