The WTO SwitchLug is a patented barrel retention device that allows the end user to change barrels on their rifle using only an inch pound torque wrench. No need for barrel vises, action wrenches, or barrel nuts! The SwitchLug is available for most custom actions, Remington 700’s, and now the Tikka T3/T3x!
Versatility: Multi-caliber capability on a single rifle platform is now an option with the SwitchLug system, at a much more cost effective price point than other switch barrel offerings. You can have a barrel chambered for a low-cost training cartridge to practice fundamentals, and a game day barrel for a more capable cartridge for shooting matches at extended ranges. Or how about a fast, flat shooting caliber for open country hunting, along with a big bore magnum for dangerous game? With the SwitchLug, it’s all possible.
Ease of Use: The only tool required for a barrel change on the SwitchLug system is an inch pound torque wrench with T25 torx bit. We offer the Fix It Sticks field kit, which includes these items and almost everything else needed for maintenance of the modern precision rifle. To install a barrel, screw it into your action until it the torque shoulder stops against the face of the SwitchLug. Then, torque the lug clamp screw to 30 inch pounds. To remove, loosen the lug clamp screw and unscrew the barrel. Since each barrel is specifically machined to match your action configuration, headspace repeats exactly during each barrel change. There is no need to reset headspace as with a barrel nut system.
Accuracy: WTO Rifles built with the SwitchLug System carry the exact same accuracy guarantee as our rifles built with traditional recoil lugs. With proper load development and shooting skills, sub .5MOA accuracy is achievable in most calibers. We use this system on a daily basis, and can count on it to work every single time.
Repeatability: Once a zero is established for a given barrel, that barrel will will return to zero within +/- .5MOA after each barrel change. This allows a shooter to have multiple barrels in multiple calibers, and recorded zeroes for each barrel. Offsets can also be entered into your Kestrel or other ballistic solver, for a seamless transition from caliber to caliber.

SwitchLug Frequently Asked Questions
Can WTO build me a custom Switchlug for my action?
No, WTO does not offer custom or one-off SwitchLugs. If a rifle/action manufacturer is interested in having a batch of SwitchLugs produced for a custom action, please reach out to us at Texasordnance@hotmail.com or use the Contact Us form HERE.
Will pre-fit barrels work on my action after a SwitchLug is installed?
The SwitchLug requires a proprietary thread tenon for proper function and a standard shouldered barrel is not compatible.
Will WTO modify my factory/prefit barrel to fit my action with a SwitchLug?
We do offer SwitchLug retrofitting for factory barrels that you send in with your action, but they must be inspected. WTO does not guarantee SwitchLug compatibility on barrels that were not originally chambered by us.
Do I have to send my action and SwitchLug to WTO everytime I need a new barrel?
No, after we chamber your first barrel, we will record your action specifications and then we can build you as many prefit barrels as you need. The only exception to this, is if you get a new bolt for your action. We will need to record the headspace dimensions to ensure proper fit and function.
Will WTO send to SwitchLugs to customers outside the United States?
Yes. We currently offer international shipping for customers outside the United States for specific WTO products like our reloading dies, tools, and SwitchLugs. Please contact us at Texasordnance@hotmail.com to place any international orders.
Does WTO currently offer dealer pricing for Switchlugs?
Yes. Please reach out to us at Texasordnance@hotmail.com and we can discuss dealer terms.
