Re: Take-down Rifle Comment

Most take-down rifles that have a quarter or one third turn disengagement use an ACME or Trapezoidal thread profile rather than the standard type V-Thread. This type of thread is significantly stronger due to the thread thickness and therefore do not push over like a a standard thread and therefore have very good wear resistance, which is why they are used for machine lead screws, jacking threads etc. You can also have the thread hard chromed which increases wear resistance.
