Guns used in the movie 28 Days Later
The British Army soldiers at the mansion in Manchester are mostly armed with L85A1 rifles, including Major Henry West (Christopher Eccleston), Sergeant Farrell (Stuart McQuarrie), Corporal Mitchell (Ricci Harnett), Private Beford (Ray Panthaki), Private Bell (Junior Laniyan), Private Clifton (Luke Mably), Private Davis (Sanjay Rambaruth), and Private Jones (Leo Bill). They are first seen when the soldiers kill an infected Frank (Brendan Gleeson). Jim (Cillian Murphy) takes Davis’s rifle at the barricade after bludgeoning him with a crowbar and then later uses it to free Mailer (Marvin Campbell), an infected soldier and to bayonet Jones. Another one is seen behind Selena (Naomie Harris) in the cottage at the end of the film. In an alternate ending, Selena (Naomie Harris) uses a L85 to shoot open a door.

The Browning Hi-Power can be seen strapped to Major Henry West’s (Christopher Eccleston) side in his dress uniform during the dinner scene and the barrel of it pops up at the end as he shoots and wounds Jim (Cillian Murphy). In an alternate ending, Hannah (Megan Burns) takes a Browning Hi-Power of a dead Jim.
The L7A2 GMPG (the British variant of the FN MAG-58) makes several appearances in 28 Days Later, and can be seen firing during the attack on the mansion.
