The Parker Hale GP-24 was a bolt-action rifle designed and manufactured by UK-based firearms company Parker Hale Ltd.
The GP-24 is chambered for 5.56 rounds and utilises 30-round STANAG magazines. It was first revealed to the public at the Shot Show in 1999 in Atlanta. It uses a Mauser-type action and an adjustable trigger. It was still undergoing field trials when Parker Hale was bought by John Rothery Wholesale. All production of firearms by Parker Hale has been halted indefinitely and thus the GP-24 remains unreleased to the public.
