INTRODUCTION
This standard is intended to outline basic performance requirements for barrel blocking devices. A
barrel blocking device is a critical piece of safety equipment used in the sport of air soft.
Air Soft tactical games are an activity that, like all sports, has intrinsic hazards. These hazards
include being hit by air soft projectiles. Protective equipment cannot eliminate all injuries but will
substantially reduce their severity and frequency. A barrel blocking device is an additional safety
device that, when meeting this standard and properly used, can substantially reduce the severity and
frequency of injuries. Air Soft gun barrels are not all the same inside diameter, thus necessitating

soft barrel blocking device technology. The intent is to revise this specification whenever substantive
information becomes available which justifies revising existing requirements or adding new
requirements.

4. Significance and Use
4.1 This specification establishes performance requirements and test methods to provide a reasonable degree of safety in the
normal use of barrel blocking devices in air soft guns.
5. Conformance
5.1 Barrel blocking devices shall not, either by label or other means, indicate conformance with this specification unless they
conform to all applicable requirements contained herein.
6. General Requirements
6.1 Performance—Upon any discharge of an air soft projectile from an air soft gun with an appropriate barrel blocking device
properly installed according to the manufacturer’s instructions, the barrel blocking device must remain inserted or over the muzzle
and prevent an air soft projectile from exiting the muzzle or the confines of the muzzle blocking device. Tests shall be conducted
in accordance with 7.2.
6.2 All barrel blocking devices shall completely cover or block the exit orifice of the barrel. Some barrel blocking devices make
use of a vent port that allows the release of excess pressure in the barrel of the air soft gun. The total calculated area of all ports
of this type in any barrel blocking device must less than 2.5 mm .
7. Test Methods
7.1 No precision statement on any of the following test methods is available at this time.
7.2 Barrel Blocking Device Retention Test:
