FOAM MOD FAQ Click HERENote: This Deploy spring was tested on a Deploy WITHOUT air re-stricter removal. Untested if the plunger would break if the restriction is removed. So removal of restrictor is at your own risk, as there are no plans for metal plungers for this model yet. However even without the removal, it still hurts like fuck with a SABOT dart.
