Introduction

The C7 is an assault rifle of Canadian origin. The C7 is a variant of the M16 assault rifle with features from both the M16A1 and M16A2. Nearly all C7 are fitted with optics, which was rather unique at the time of introduction.

Design

The C7 can be considered an M16A2 with M16A1 rearsights and the ability for fully automatic fire. It uses the same direct impingement gas system as used in the M16. Most C7 are of the flat top model and are fitted with the Elcan 3.4x scope. The C8 is the carbine model derived in a similar way from the C7 as the M4 from the M16A2. Unlike the M4 in US service the C8 was not fitted with a heavy barrel at first. Additionally a range of special models was developed in Canada that includes models for special forces, a light support weapon and marksman rifles.

Firepower

The C7 fires the 5.56x45mm NATO round from 30 round magazines. It is a select fire rifle with a cyclic rate of fire of about 700 to 900 rpm. The maximum effective range for the C7 is about 400 meters and for the C8 it is 300 meters. As with the M16A2 the accuracy is very good although the weapon needs constant cleaning in order to maintain reliability. It is possible to mount the M203 or AG36 under barrel grenade launcher.

Users

The C7 became the standard issue assault rifle in Canada, Denmark and the Netherlands. It was adopted by many nations in smaller quantities to supply special forces. In Canada and the Netherlands the exsisting C7's in service are being modified to extend their capabilities and service life.

Variants

C7

The C7 is the Canadian version of the M16 and has the Colt model number R715. The C7 is based on the M16A1, but features many improvements found on the M16A2. These improvements included a heavier barrel and rifling twist rate for the 5.56x45mm NATO round. Unlike the M16A2 used by US forces the C7 is capable of fully automatic fire. The C7 has a fixed metal handguard with M16A1-type iron sights. The more common C7A1 has a flat top receiver that is fitted with a Weaver accessory rail that allows optics to be mounted. Originally the C7A1 was known as the C7 Flat Top, or C7FT.

C7A2

The C7A2 is an improved model of the C7A1 and features a variety of upgrades. The C7A2 is fitted with the retractable stock of the C8 carbine, has ambidextrous controls, a green furniture and additional accessory rails. The orignal Weaver rail is replaced by a Picatinny rail, which has become the international standard for mounting accessories.

The C7 NLD is a similar upgrade for the Ducht forces. The modifications include a retractable stock, a variety of accessory rails, a tactical light, a grippod and new optics.

C8

The C8 is the Canadian counterpart of the American CAR-15 carbine and has the Colt model number R725. Compared to the C7 the C8 features a retractable stock and shorter barrel and handguard. The C8A1 has a flat top receiver with Weaver accessory rail instead of a carrying handle. Originally the C8A1 was known as the C8 Flat Top, or C8FT. The C8 and C8A1 feature the thin barrel profile of the CAR-15, but with rifling for NATO ammunition. The C8 Heavy Barrel, or C8HB, has the same thicker step cut barrel as the American M4 carbine. The C8HB is now known as the C8A2.

C8 SFW

The C8 Special Forces Weapon was developed for special forces use. The C8 SFW has a longer, stepped barrel that thickens near the muzzle. This results in a longer effective range while retaining the compactness of the C8. The C8 CQB is a subcompact version of the C8 with a very short barrel. Only the flash hider and front side protrude from the handguard.

C7 LSW

The C7 Light Support Weapon is a co-development between Diemaco and Colt. Unlike the heavy barrel M16A1 it is more than a simple modification of the baseline assault rifle. The C7 LSW has a fixed heavy hammer forged barrel that is encased in a large square handguard. The rate of fire is lowered and a bipod is fitted. Early versions had a bipod near the muzzle and fired fully automatic only. Later versions have the bipod placed under the handguard, also allow for semi-automatic fire and feature accessorry rails near the front sight. The C7 LSW has a fixed sights and the C7A1 LSW has a flattop mount similar to the C7A1. Colt sells the Canadian produced C7 LSW with Colt markings as the M16A2 HB R750.
