Also known as: FN Model D, FN Type D, FN Mle 1930, FN BAR Type D

Overview

The FN BAR Model D is a Belgian gas-operated, magazine-fed automatic rifle and squad light machine gun built by FN Herstal as an improved derivative of John Browning's M1918 Automatic Rifle. Chambered in .30-06 Springfield and other military calibers, the Model D (Type D) added a quick-change barrel, a pistol grip, a redesigned receiver for easier maintenance, and a dual-rate fire selector for slow and fast cyclic rates. Fed from a 20-round detachable box magazine and supported on a bipod, it served Belgian forces and was exported widely from the 1930s through the post-war decades.

Notes

The Model D (Type D) was FN Herstal's most refined BAR variant, distinguished from the American M1918 by its quick-change barrel and modular receiver. FN produced BARs in several chamberings including .30-06 Springfield, 7.92x57mm Mauser, and 7.65x53mm for various export customers.

Background

Where the American BAR stayed largely unchanged, FN Herstal kept refining Browning's design. The Model D's quick-change barrel let gunners sustain fire without cooking off a fixed barrel, and its dual-rate selector gave squads a slow setting for controllable bursts. FN BARs soldiered on with Belgian and export forces well into the Cold War.
