The two rifles of concern are the Remington Model 700 and the Model Seven with X-Mark Pro (XMP) triggers, manufactured between May 1, 2006 and April 9, 2014 and sold nationally by licensed dealers.

The ACCC understands that over 21,000 of these rifles have been imported and approximately 4,000 are still within the supply chain.

"The ACCC is concerned that around 17,000 rifles in the hands of gun owners across Australia may unintentionally discharge without touching the trigger," CCC deputy chair Delia Rickard said. "These rifles are currently under recall in the United States.

"Although there have been no reports of injuries in Australia or the United States, care should be taken when handling these rifles," Ms Rickard said.

The ACCC urges owners of those models to follow the safety steps:

. Stop using your rifle - any unintended discharge has the potential to cause injury or death.

. Take extreme care when unloading - make sure you always keep the muzzle pointed in a safe direction. 

. Leave your rifle safely stored - don' t attempt to diagnose or repair the rifle.

Remington proposes to replace XMP triggers in all affected rifles free of charge.
