Canada used the FN FAL from the 1950s to 1984. My friend's father is in the navy and said the gun wasn't very good. It has too much recoil and too small of a clip compared to the current service that we use, the Diemaco C7A1 Assault Rifle. The C7 features the structural strengthening, improved handguards, and longer stock developed for the M16A2. Diemaco changed the trapdoor in the buttstock to make it easier to access and a half-inch spacer is available to adjust stock length to user preference. The most easily noticeable external difference between American M16A2s and Diemaco C7s is the retention of the A1 style rear sights. Not easily apparent is Diemaco's use of hammer-forged barrels. The Canadians originally wished to use a heavy barrel profile instead of the M16A2 profile, but Colt denied permission. Also, Diemaco has developed a different mounting system from Colt for the M203 grenade launcher for the C7 rifle family.
