Insure Improper Assembly

Check for Missing Parts

Cracks: all cracked parts are cause for concern, but especially so in the chamber-area, bolt, bolt-lugs, or buttstock.

Bore obstructions: being either dented or bent barrels, or foreign material in barrels.

Improper Headspace: dimensions concerning the relative space of the chamber and the bolt are not within specified tolerances.

Improper Timing: (applies to fully automatic firearms and revolvers).

Safety-Mechanism Malfunctions: potentially allowing a firearm with the safety mechanism supposedly engaged to unexpectedly fire.

Worn Sear Edges: potentially allowing a firearm to unexpectedly fire when the safety mechanism is disengaged.

Firing-Pin Tips Deformed: leading to the possibility of primer-rupture.
