The Colt Canada C8 carbine range are carbine variants of the C7 family, and is mechanically and aesthetically very similar to the Colt 653. Colt made the initial C8s for Canadian Forces as the Colt Model 725. The C8 has a 368 mm (14.5 in) A1 profile barrel like the Colt Model 653 M16A1 carbine, but with a 1 in 180 mm (7 in) rifling twist appropriate for the 5.56×45mm NATO C77 cartridge. The C8 incorporates the design improvements featured on C7 assault rifles. The C8 has a cyclic rate of fire of around 750–950 rounds per minute (RPM).
C8A1
[編集]The improved C8A1 (Diemaco C8FT) is essentially a C8 carbine with a C7A1 flat-top upper receiver; the carbine having a 36.8 cm (14.5") barrel versus the 50.8 cm (20") barrel typically seen on the C7.[1] The overall layout of the weapon remains essentially unchanged except for the upper receiver and the general inclusion of the C79 sight. C8A1s have also been more commonly seen with the detachable carry handle with A1 sights developed by Diemaco for both the C7FT and the C8FT. The C8A1 was never officially adopted by the Canadian Forces and was only used in Afghanistan for the ability to use the C79 optical sights.
C8A2
[編集]The C8A2 carbine is very similar to the C8, but having a cold-hammer forged heavy 14.5" barrel (as opposed to the 14.5" pencil-profile barrel) and a flat-top upper receiver.
C8SFW
[編集]The Special Forces Weapon (SFW) features a longer, 400 mm (15.7 in) barrel of a heavier profile than the C8A1. It is designed to provide a fire support capability in carbine form. A sleeve, called the simon sleeve, is slipped over the end of the barrel and is retained by the compensator and its crush washer. It is used to mount bayonets and M203A1s. The front sight base is strengthened for mounting of the Heckler & Koch AG-C/EGLM grenade launcher. The British military acquired a number of SFWs, primarily for their special forces, under the designation "L119A1" but has since been upgraded to "L119A2" specifications.[要出典] This version of the C8 is also in service with the Norwegian Special Operations Command.
C8FTHB
[編集]Concerns that Princess Patricia's Canadian Light Infantry had with the C8 led to the creation of the C8FTHB. The C8FTHB (Flat Top Heavy Barrel) features numerous improvements over the C8, including a heavy profile cold hammer-forged M4 profile barrel featuring a grenade launcher cut out for mounting of the Canadian Forces M203A1 and bayonet and Elcan C79 Optical Sight.
Some of the earlier C8FTHB carbines used old refurbished C8 receivers. "FTHB" was stamped next to the C8 markings on the lower receivers. Colt Canada later manufactured new lower receivers with C8FTHB markings. Later, C8FTHB carbines that were upgraded to the C8A3 had "A3" stamped next to the markings, giving "C8FTHBA3" markings. Only 400 C8FTHBs were upgraded to C8FTHBA3s before Colt Canada started simply marking new receivers "C8A3".
C8A3
[編集]The C8FTHB was quickly replaced by the C8A3, which features the same cold-hammer forged barrel and flat-top upper receiver as the C8FTHB as well as all the mid-life upgrades that appeared on the C7A2 such as the green furniture, ambidextrous charging-handle latch, magazine release and selector lever. It also includes the TRIAD I rail for C8, which has one slot less than the C7 TRIAD I, to accommodate the M203A1 sight.
Other C8 variants
[編集]Two additional C8 variants exist. The C8CQB is similar to the Mark 18 Mod 0 CQBR, having a 250 mm (10 in) or 290 mm (11.6 in) barrel and a Vortex Flash Hider made by Smith Enterprise Inc.[2] The smaller Personal Defense Weapon (PDW) variant has an overall length of 530 mm (20.7 in) with stock fully retracted. It has a 140 mm (5.7 in) barrel and the receiver extension has been shortened by 42 mm (1.65 in).
In 2011, the Royal Canadian Mounted Police adopted the C8 IUR (Integrated Upper Receiver) with ancillary components as their patrol carbine.[3][4] These rifles have been built as semi-automatic only.
This version (C8 IUR) is also operated by all 4 branches of the Danish Defence,[5] and the Danish Security and Intelligence Service´s AKS. (S.W.A.T)
