The sights are military-style ghost ring and are adjustable in the field using only a cartridge rim.

The bolt has a two large locking lugs with a recessed face fully enclosing the cartridge rim.

Secondly, the higher pressure created in the chamber could jam the bolt, leading to the extractor claw failing to extract the cartridge and only breaking off the cartridge rim, leaving it stuck in the chamber.

Care needed to be taken when loading the magazine to ensure that each round went ahead of the previous round, so that the .303 cartridge rims did not overlap the wrong way, which would cause a jam.

The bolt face was enclosed so that it fully surrounded the cartridge rim, in a similar way to the Remington 700 bolt.

This type of extractor does not engage the cartridge rim as it rises from the magazine into the action, but rather clips over the cartridge rim after the cartridge has been pushed into the chamber and the bolt handle is turned down.

Then slide the cartridge into the faucet body by pressing down on the cartridge rim.
