The Gen4 has a load collar that screw-ons to the device. It holds the blanks/adapters in place, allowing the user to launch a rescue flare by hand for an emergency rescue.
The Gen4 can also be used to set a tripwire perimeter, just like the classic design.
COMPATIBILITY:works with 12 gauge blanks and flares, plus our .22 adapter, 209 primer and digital adapters. NOT COMPATIBLE with our 308 adapter.
NOTE: Avoid using blanks with brass hulls. Brass hull mushrooms out after detonating. Removing a mushroomed blank is difficult.
