If the headspace is too short, ammunition that is in specification may not chamber correctly. If headspace is too large, the cartridge case may rupture, possibly damaging the firearm and possibly injuring the shooter. Headspacing is automatically done when orders are placed with both barrel and bolt or bolt carrier groups.


Additional shipping may apply to barrels and bolts being sent in for headspacing
