Ruger Mark II Pistol Question

cbxjeff

I've been told that the barrel is threaded into the receiver and can be removed. Is this correct?
Thanks guys,

Yes they are Threaded BUT It acts like they are lock tightened to 1000 foot Pounds. I have removed loads of Military rifle barrels With barrel and action wrenches. But never been able to get Ruger barrel Off a pistol. Maybe you will have better luck

The barrel is threaded into the receiver at 80 foot-pounds of torque.

Ruger actually threads the finished barrel into an unfinished receiver, torquing to the 80 foot-pounds, then finishes the milling process of the receiver -- this avoids any "timing" of the barrel and receiver during the factory assembly process. (The front sight base on the tapered barrel is a milled part of the barrel, so timing the union would be needed if a finished barrel was being threaded into a finished receiver.)

Re-barreling will require "timing" -- one would want to use a thread-locking compound if the full 80-foot-pounds wasn't achieved with a new barrel.

Some of the major gunsmithing tool suppliers sell jigs for supporting the barrel and receiver; though a good gunsmith should be able to make his own.

If the old barrel being removed isn't being saved, turning the barrel/receiver on a lathe to remove the material of the barrel where it meets the receiver can be an easy way to relieve the torque/friction of the union so the old barrel can be removed from the receiver easily. (Or one could do it carefully and slowly with a file.)

I have a video tape from Clarks Gunsmithing with Jim Clark Jr. removing a barrel from a MKII.He makes it look easy.I also have a bunch of MKII new takeoff barrels I bought from Volquartsen about 10 years ago that show no damage from being removed.

Volquartsen also does barrel replacements. They actually have a full line of accessories for the MK-II.

One thing that the home gunsmith wants to be careful with, is that the barrel/action/upper assembly of the Ruger's are the part that contains the serial number. Yes, that is right, that it IS the part that is considered to be "THE GUN". The average JOE, non-FFL holder cannot purchase that assembly, without having it sent to an FFL.

I am thinking that in today's litigative world, that there would be thread locking compound used at the factory, in addition to the 80 ft-pounds of torque.

Tactical Solutions, is another fine manufacturer, of lightweight components for your Ruger MK-II.
