XLR Titanium Action Screws
These XLR Titanium Action screws are replacement action screws.
In search of the lightest build? Replace the steel factory action screws that ship with your XLR Element 4.0 MG with the XLR Titanium Action Screws from Bison Tactical.
According to XLR these screws should work with the following actions (verify fitment due to inconsistencies across platforms):
- 700 SA (clones)(Short Actions)
- Medium custom actions (like the Bighorn Arms Medium ORIGIN Action)
- 700 LA (clones)(Long Actions)
- Savage SA (Short Action)
- Savage LA (Long Action)
In trying to achieve a 7.5 lb rifle as seen in this blog post “Ultralight Bolt Action Rifle“, I found I could save ounces by replacing my action screws with titanium ones. Since my action is also Titanium (Zermatt Arms Ti-3 Short Action), why not go with XLR Titanium Action screws?
Reuse any washers that come with the factory action screws.
Check fit for interference of the action screws with your action’s bolt.
The longer of the 2 action screws is a full 2″ while my factory long action screw measures 1.96″. For mine to work perfectly I had to use a file to remove a small amount of material from the threaded end of the action screw so it doesn’t over penetrate the action whole and interfere with the bolt cocking piece. You may need to make this same modification.
Included in your package is a very small nylon washer. This can be used to take up some space between the action screw head and the chassis to reduce interference with the bolt cocking piece. However the best solution is if you have this issue to file down the screw to fit your chassis/action. If you use the nylon washer – be sure to frequently check your action screw torque to make sure it is not loosening. The Nylon washer has a Rockwell Hardness of 117
When assembling your chassis remember to use anti-seize to prevent galling of the screws/action.
The socket head is the same hex as the factory action screw. However for ease of use I recommend a 2″ extended bit to make it easier to access the long action screw.
As a reminder chassis action screw torque settings are 65 in /lb. Here is a link to the XLR torque spec sheet in case the below image becomes out of date.
