    Installing a tactical bolt knob on a Mauser

    I have had a target/sniper style rifle built on a Yugo Mauser action with a Parker Hale target barrel for some time. The bolt handle was forged, and was about 2.5" long. Which I felt was a bit short. So, I decide to lengthen it and install a tactical style knob. I checked with a gunsmith who wanted $125 to weld on a new bolt handle, and I decided that was too much.

    I got a tactical weld on handle threaded for a screw on bolt knob and the knob from PTG(Pacific Tool and Gauge). The handle is actually for a Remington 700, but I thought I could modify it to make it fit. After trimming everthing off I thought I would need to trim to make it fit right, the length would not be much longer than what I already had.

    Once I got it, I wasn't sure I liked how much I would have to take off and the styling. So, I decided to modify the bolt handle that was already on the Mauser. The orignal bolt handle with knob was 2.5" long, and the knob is about .8" in diameter. The tactical knob is 1.324" long, and threaded inside to a depth of about .5", though the PTG handle is only threaded to .4".
    I took a cut off grinder, and using the side of the cut off blade started cutting/grinding the sides, top and bottom of the ball until I had it roughly square. Then I ground down the corners till I had an 8 sided shape. From there I rocked the cutoff grinder back and forth getting a roughly shaped cylinder. I tried to maintain the same angle as the handle shaft.

    Once I was close to the right shape and size, I used sandpaper to smooth things up. That is what I had, and I didn't want to go to the hardware store and get some emory cloth.
    I started with 100 grit, and worked my way to 600 grit. I used strips about 1" to 1.5" wide, and worked in a back and forth action like I was shoe shinning.
    I kept moving around the handle so I could round it out.

    How to install a tactical knob on a Mauser, continued.

    Once that was done, I had to locate a 5/16 x 24 tpi die, to thread the handle. Once I got it threaded, I screwed on the knob. Overall length is now 3.55". Roughly a 40% increase in length, and corresponding reduction in lift forces due to increased leverage.
    Here are before and after photos:



    Now I have to refinish the handle and whole gun. I am going to park it with Black park. Once that is done, I will loctite the knob on.

            It shoots pretty good. However, I am looking to do a barrel change. Barrel twist is set for 147 - 150 gr bullets but seems to function okay with 165 gr. However, the bore is very tight at about .295", meaning I cannot shoot any ammo intended for any other guns in it as I get pressure problems.
            These loads were just thrown together. No work up was done.
