Frequently Asked Questions

What are the critical torque specifications for assembling a bolt-action rifle like the Aero Precision Solus build?

For this build, the barrel installation requires a torque of 75 ft-lbs. The action screws securing the barreled action to the chassis are torqued to 60 in-lbs, starting with the front screw.

How is headspace verified during a bolt-action rifle assembly?

Headspace is verified using 6.5 Creedmoor Go and No-Go gauges. The bolt must close completely on the Go gauge and fail to close on the No-Go gauge. Proper alignment with the bolt extractor is essential for accurate readings.

What specialized tools are recommended for assembling a precision bolt-action rifle?

Essential tools include a Short Action Customs Modular Barrel Vise, an Aero Precision Solus-specific action wrench, a calibrated torque wrench, Allen wrenches, and headspace gauges. Specialized lubricants like Brownells Action Lube Plus are also recommended.

Can an MDT 12-round AICS magazine be used for both .308 Winchester and 6.5 Creedmoor?

Yes, the video demonstrates that an MDT 12-round metal AICS-pattern magazine, although marked for .308 Winchester, functions perfectly with the 6.5 Creedmoor caliber in this specific bolt-action rifle build.
