Outside of visual signs of wear, we will also check the mechanical functionality of the firearm. We do this in a variety of ways, including cycling of dummy rounds to check feeding, chambering, extraction, and ejection. Function check of the fire control system includes:
- Dry Fire
- Trigger Reset
- Manual Safety Function
We will also measure the headspace of your firearm. Headspace is the fit between the cartridge case and the chamber in the axial direction. It is important for both safety and accuracy. Proper headspace prevents the casing from deforming too much under pressure which can lead to case failure. Optimized headspace helps accuracy by making the cartridge fit more concentrically in the chamber, as well as reducing the “flow” of brass to the front of the case allowing more reloads.
