Mark Johnson's Review of JP Enterprises Jam Nut 5/8X24

I use jam nuts rather than crush washers or shims although they work fine also. Timing is easy and repeatable. Experimenting with muzzle devices is simplified. JP nuts are quality threaded and ground for a good interface and lockup. These are not cheap but you don't want to skimp when you need a threaded and ground locknut.
Pros:
  • Quality
Cons:
  • Not cheap but worth it
Best Used for:
  • timing barrel devices
Would Recommend: Yes
