Ruger MkIII/MK IV Bolt Racker
The MK Machining Ruger MkIII/MK IV Bolt Racker allows for easy bolt racking on your Ruger Mk III or Mk IV pistol.
Available in the following styles
Left/Right Handle
Winged Handle
Loop Handle
Due to varying bolt to receiver tolerances across many thousands of pistols insure that your bolt racker is not preventing the bolt from being fully in battery. It may be necessary to perform light filing to ensure proper function.

Product is not “machined” as I expected nor is it described to be however it is made from a molded product of some sort that does not hold up. Within 2,000 rounds it broke of the end of the bolt.

Hi Mark,
Please get in touch via support@mkmachining.com so we can help you out, this is the first failure we have heard on this part and I’d like to examine the break line and see how we can refine further!
Correct, it’s not machined, and as you mentioned is not described as such. We take care to label everything correctly including our manufacturing processes.

I have both the MK and the TK rackers. the MK holds up as well and looks/feels better than the aluminum variety.
