Diemaco C7A2 Rifle
A 'mid-life' upgrade for the C7 family with Elcan C79A2 optical sight, a Triad mount for laser designator and tac lights, and telescoping butt stock. Replacing C7A1s.
Rifle, Automatic, 5.56mm, C7A2, Calibre: 5.56x45mm NATO (or .223" Remington), Origins: Updated C7/C7A1, Diemaco Inc, Kitchener (now Colt Canada).
C7 and C7A1 Rifles
The Diemaco version of the Colt AR-15A1/A2 automatic rifle. The first 'iron sight' C7 rifle entered service in 1984, followed in 1990 by the flat top C7A1 with an Elcan C79
3.4x magnified optical sight.
CF designation: Rifle, Automatic, 5.56mm, C7 [... C7A1] , Calibre: 5.56x45mm NATO, Origins: Diemaco Inc, Kitchener (parallel
development to US Colt M16A2/AR-15A2).
 There was a third original Diemaco AR-15 type weapon, the Rifle, .22-calibre, C10. DND then cancelled this semi-automatic training rifle in .22" Long Rifle (5.6×16mmR ).
C8A3 Carbine 
The C8A3 carbine is a 'new build' C8FTHB (below) with FT upper receiver and 40cm barrel. The C8A3 features a TRIAD mount, Ambi-Catch magazine release, and green plastic 'furniture' similar to that
of the C7A2 upgrade, etc.
CF designation: C8A3 - Carbine, Automatic, 5.56mm Colt, Calibre: 5.56x45mm NATO, Origins: Colt Canada, C8A3 can be considered a production version of the C8FTHB.
 'C8A3' is the maker's designation. The 'missing' C8A2 was a Danish Army carbine.
C8FTHB Carbine 
The C8FTHB (for 'Flat Top, Heavy Barrel') is a C8/C8A1 upgrade roughly equivalent to the C7A2 'mid-life' albeit on a more modest scale. The C8FTHB, as the designation implies, uses a 'flat top'
C8A1-style upper receiver – with its built-in Weaver rail mount for sights – and a heavier, heat-dissipating 40cm barrel.
CF designation: No confirmed 'C' designation
(C8FTHB is a marketing name), Calibre: 5.56x45mm NATO, Origins: Diemaco (now Colt Canada), simplified Diemaco C8SFW.
 The C8 update is variously referred to as the C8FTHB, C8A1HB, C8SFW or 'C8A2'.
C8 & C8A1 Carbines
The C8 and C8A1 are short versions of C7 / C7A1 rifles. C8s have iron sights, C8A1s have opticals. Both carbines have telescoping buttstocks and 38 cm barrels – vs 53cm for C7s.
The new C8FTHB is a C8/C8A1 update program.
CF designation: Carbine, Automatic, 5.56mm, C8 [C8A1] , Calibre: 5.56x45mm NATO, Origins: Diemaco Inc, Kitchener (Colt
Model 725, equivalent to US M16A2 carbine).
