Frequently Asked Questions

What makes the Farquhar-Hill rifle unique among WWI firearms?

The Farquhar-Hill is notable for its advanced gas-operated system featuring a buffered piston and dual mainsprings, designed for consistent cycling. It also possesses a unique drum magazine with receiver-integrated feed lips and can convert to a manual bolt-action mode.

How was the Farquhar-Hill rifle adopted by the British military?

The British military adopted the Farquhar-Hill in 1917 for aircrew use and ordered 100,000 units in 1918. However, the war's end prevented large-scale production, leaving only a few dozen examples extant.

What is the significance of the Farquhar-Hill's bolt design?

Its bolt features a two-lug rotating design that incorporates 'primary extraction.' This mechanism slightly unseats the cartridge case during initial rearward movement, significantly improving reliability, especially in dirty or fouled chambers.

Can the Farquhar-Hill rifle function as a bolt-action firearm?

Yes, the rifle is equipped with a manual override that disconnects the gas system. This allows it to be operated as a manually cycled, straight-pull bolt-action rifle, offering versatility in its function.
