FUNCTIONAL FEATURES OR DETAILS COMMON TO BOTH SMALLARMS AND ORDNANCE, e.g. CANNONS; MOUNTINGS FOR SMALLARMS OR ORDNANCE

Introduced: January 1990

Description

F41A covers functional features, mechanical components, and structural details applicable to both small arms (rifles, pistols, machine guns) and ordnance (cannons, artillery). This includes breech mechanisms, firing systems, recoil management devices, ammunition feeding systems, and barrel designs shared across weapon categories. The classification also encompasses mounting systems and support structures for securing weapons on platforms or vehicles. Adjacent classes F41B and F41C provide more specialized coverage for small arms and ordnance respectively, making F41A the appropriate classification for generic or dual-purpose weapon technologies.

IPC and CPC are identically structured here. All 19 subcodes exist in both systems.

11 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1990.
