The FAMAS G1 was developed as a lower-cost option for FAMAS export sales. The original F1 model had been offered for international sale, but it attracted little interest largely because of its high price. In response, GIAT created the G1 with many of the extra features left optional. This allowed them to reduce the price by up to 40%. Specific feature reductions included:
- Omitting the bipod legs
- Omitting the grenade launching sights and barrel fittings
- Omitting the night sights
- Omitting the burst fire mechanism
- Replacing the trigger guard with a molded whole-hand trigger guard

The mechanism stayed the same, and all of the omitted features could be included as options. This still failed to generate any export sales, in part because GIAT came under ownership of FN, and FN's competing assault rifle options were more profitable than the FAMAS.

The G1 did contribute elements like the whole-hand trigger guard to the mid-1990s G2 model adopted by the French Navy, however.

Many thanks to the IRCGN (Institut de Recherche Criminelle de la Gendarmerie Nationale) for allowing me access to film this FAMAS variant for you!
