Currently Canadian army is upgrading existing C7 and C7A1 rifles in Canadian service to new C7A2 configuration, which combines the standard C7-type 50cm barrel with C8-type telescoped buttstock, colored furniture, C7A1-type Picatinny rail upper receiver, and additional short Picatinny rails on the sides of front sight block for mounting sighting aids like laser pointers and tactical lights. C7A2 also is fitted with improved sight, Elcan C79A2. Other changes include ambidextrous magazine release and safety/fire selector switch, and other minor improvements.
|Diemaco C8A1 carbine|
Internally, the C7 differs very little from the original M16A1 rifle, with the most visible differences being the heavy M16A2-style barrel and A2-style handguards. Flat top models (C7FT / C7A1) are quite similar in appearance to the M16A3 rifles, and issued with Elcan optical sight along with backup iron sights. The C8/C8FT carbines are quite similar to the US M4/M4A1 carbines.
