Frequently Asked Questions

What tools are needed to swap the barrel on a Gunwerks Nexus/NX2 rifle?

You will primarily need a T25 Torx driver for all action and barrel clamp screws. Additionally, a torque wrench calibrated to 60 inch-pounds is essential for proper reassembly. A plastic or rubber mallet may be helpful for the bolt cross pin.

What is the correct torque specification for the barrel clamp screws on a Gunwerks Nexus/NX2?

The barrel clamp screws on the Gunwerks Nexus/NX2 should be torqued to 60 inch-pounds. This process should be repeated three times for each screw, ensuring even pressure and a secure barrel fit.

When do I need to swap the bolt head on my Gunwerks Nexus/NX2?

You must swap the bolt head if you are changing from a standard bolt face barrel (like a 6 Creedmoor) to a magnum bolt face barrel (like a 7 PRC or 300 PRC), or vice versa. The correct bolt head is crucial for proper chambering and extraction.

How do I safely remove the firing pin shroud assembly for a bolt head swap?

To remove the firing pin shroud, push on the sides of the shroud to relieve pressure, not on the cocking piece. Then, push the bolt handle slightly out of battery. This will allow the firing pin assembly to be removed from the bolt.
