bolt handle conversion on a remminton factory bolt

Re: bolt handle conversion on a remminton factory bolt

Another vote for the Tac Ops Bolt Knob Conversion - the best designed and thought-out bolt knob design around. Forget about the Badger and the rest of the bolt knobs that shorten the bolt handle. Shortening the bolt handle decreases clearance between the bolt knob and the shooter's hand as well as the clearance between the bolt knob a scope's ocular bell.

Why would anyone want to <span style="font-style: italic">decrease</span> clearance, <span style="font-style: italic">increasing</span> the possibility of bumping fingers on the scope ocular while operating the bolt? This can be a problem for shooters with large hands and/or when shooting with gloves on. Extra clearance also helps keep the shooter's hand from pressing up on the bolt handle, which in certain cases can be detrimental to lug engagement and bullet alignment.

Functionally-speaking, a slightly longer bolt handle combined with a moderately-sized bolt knob allows the bolt to be operated more smoothly because of the additional clearance between the shooter's fingers' and the ocular bell. A longer bolt handle also creates slightly more clearance between the shooter's index finger and the bolt knob while shooting. The Tac Ops Bolt Knob Conversion is also extremely strong because a hardened threaded stud is TIG welded to the bolt handle itself.

The Tac Ops Bolt Conversion actually adds more clearance by lengthening the bolt handle slightly through the installation of the hardened, threaded steel "bung". This is preferred over shortening the bolt handle (as with most other bolt knobs) because shortening the bolt handle reduces the operating clearance between the bolt knob/fingers and the scope's ocular bell. Randy from R & D Precision in California (HateCA) said <span style="font-style: italic">Sounds like you might need a longer bolt handle"</span> to <span style="font-style: italic">banks74</span>.

If, for some strange reason - someone wants a short bolt handle like with other bolt handle installs, the bolt handle just needs to be cut a bit shorter before the "bung" is TIG welded on. However, shortening the bolt handle somewhat defeats the purpose of changing the bolt knob because this decreases the <span style="font-style: italic">working clearance</span> between the scope's ocular bell and the shooter's fingers.

Shown below are some photos' of a Tac Ops Bolt Knob installed on a RH SA M700 bolt (from my personal X-Ray 51) and a competitor's bolt knob installed on a LH SA M700 bolt (from a friend's rifle built by a competitor). Keep in-mind that the competitor's bolt handle isn't even as short as most others, which are sometimes so short that the shooter can barely grasp the knob without fingers hitting the ocular bell.

And again, if for some strange reason someone actually wanted a shorter bolt handle this is easily accomplished by cutting the shank shorter before welding the threaded insert to the bolt handle. That said, compare the <span style="font-weight: bold">length of the handle and the diameter of the threaded shank</span> of the Tac Ops bolt to the length of the handle and the diameter of the threaded shank of the competitor's bolt:

Now on the rifles. Getting the angle the same for both guns was tricky, so it may be difficult to see the actual clearance difference in in the photos. However, in person the clearance delta is substantial.

<span style="font-weight: bold">Look at the clearance between the bolt knob's "top" and the stock on this Tac Ops Bolt:</span>

Below are a bunch of photos I borrowed from <span style="font-style: italic">monteboy84</span>'s <span style="font-weight: bold"><span style="font-style: italic">"Some bolt knob install pictures"</span></span> thread. Bolts are shown in various stages of the Tac Ops Bolt Knob Conversion. I highly recommend that the TOBKC be installed by <span style="font-style: italic">monteboy84</span>, because it is NOT a DYI install.

Re: bolt handle conversion on a remminton factory bolt

If you search "Badger Ord" on eBay, I found a seller who sells the bolt handle and the service to turn and mount the handle including shipping door to door for about $50ish. And its pretty solid work, still using it to this day. Something to look into.

Yes it can. Below are some photos of a Tac Ops Bolt Knob Conversion installed on a Tac Ops Lima 63 (30.06) built on a Savage 110. I borrowed these photos from <span style="font-style: italic">"AIAE"</span> (the Sniper's Hide member formerly known as <span style="font-style: italic">"Savage110"</span>).

Re: bolt handle conversion on a remminton factory bolt

im likeing the tac ops for the welded joint and threaded stud. i can try a few knobs out and deside whats best, plus it looks like it could add some length to it

A little length is added to the the factory bolt handle when the hardened boss is welded to the bolt handle shank, although you can keep the handle short like other bolt knob conversions by cutting a little extra off the bolt handle shank before welding the hardened boss onto the handle.

Another thing I really like about the TOBKC is that the addition of the welded boss/insert provides a smooth, rounded transition from the bolt handle to the bolt knob. Without the round boss/insert you have a round bolt knob attached directly to a square bolt handle, like most others. Personally, I think the abrupt change from the square handle to the round knob looks like crap. Unfortunately that describes most aftermarket bolt knobs.

Possibly, but I don't know for sure. Its' my understanding that installs on Savages are more of a PITA than on a Remington. I also know that <span style="font-style: italic">monteboy84</span> has installed the TOBKC on Savages, Winchester/FN SPRs', and Howas', but since Tac Ops built the Lima 63 the bolt knob conversion was probably done in-house at Tac Ops (and <span style="font-style: italic">monteboy84</span> doesn't work for Tac Ops).

Re: bolt handle conversion on a remminton factory bolt

Thanks a lot Aries, much appreciated. I don't wanna steal the thread but I don't wanna start a new topic, does anyone recommend someone to install a Surgeon knob on a Savage bolt handle? If it's better to start a new topic just let me know.
 
Re: bolt handle conversion on a remminton factory bolt

I'm going to have to say big +1 to mark at short action customs. I'm waiting on my rifle to come back and can't wait. Mark has been really helpful everytime I have talked to him.
