If you would like us to check the headspace of your barrel and bolt prior to shipment, please add this service to your cart with the parts to be checked. Orders with this service may experience a slight delay in shipping.
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.
Additional shipping may apply to barrels and bolts being sent in for headspacing
