Assault Rifles

Diemaco C7FT (M16 A2)

Calibre: 5.56mm NATO round
Capacity: 30 rounds
Barrel: Hammer Forged
Barrel Length: 50cm
Length: 100cm
Weight: 3.2kg (empty) 3.7kg (loaded
Rate of fire: 700 – 900RPM

The M4 was replaced by the Diemaco C8 Carbine, so I think it is a fair assumption that the M16 may well have been replaced by the Diemaco C7FT, as such the statistics are for the C8, however they are virtually identical.
The C7FT Rifle has a Flat Top upper receiver with Standard Weaver / Picitinney sight rail permitting the use of a full range of sighting and tactical accessory options.
The C7FT Rifle has a firing mechanism that permits either single shot or full automatic firings. A 3 round burst option is also available.
The rifle is designed and configured to be easily operated and maintained under severe military service conditions.
This rifle can be operated either right or left handed without modification or reconfiguration.
All user maintenance is performed without tools, and all armourer maintenance can be performed at the unit level, with a minimum of special tools and gauges.
The C7FT Rifle is fully compatible with cold weather clothing, NBC equipment/protective gear, night vision sights and devices, and simulation/training systems.


The M16A2 5.56mm rifle is a lightweight, air-cooled, gas-operated, magazine-fed, shoulder- or hip-fired weapon designed for either automatic fire (3-round bursts) or semiautomatic fire (single shot) through the use of a selector lever. The weapon has a fully adjustable rear sight. The bottom of the trigger guard opens to provide access to the trigger while wearing winter mittens. The upper receiver/barrel assembly has a fully adjustable rear sight and a compensator which helps keep the muzzle down during firing. The steel bolt group and barrel extension are designed with locking lugs which lock the bolt group to the barrel extension allowing the rifle to have a lightweight aluminium receiver.

The M16A2 rifle is a product improvement of the M16A1 rifle. The improvements are:
an improved rear sight which can be easily adjusted for windage and range
a burst control device, that limits the number of rounds fired in the automatic mode to three per trigger pull, which increases accuracy while reducing ammunition expenditure
a muzzle compensator, designed to reduce position disclosure and improve controllability and accuracy in both burst and rapid semi-automatic fire
a heavier barrel with a 1 in 7 twist to fire NATO standard SS 109 type (M855) ammunition which is also fired from the M249 Squad Automatic Weapon (SAW). This further increases the effective range and penetration of the rifle cartridge.


Heckler & Koch G36K

Calibre: 5.56 x 45mm NATO (.223 Remington).
Sight: 1) Dual sighting system – 3.5x. 2) Export Sight – 1.5x.
Magazine: 30 round
Trigger Groups: safe, semi-automatic and fully automatic
Buttstock: Folding buttstock
Weight: 7.28lb
Length: 39.29″ with stock out
Known to have been used by the SAS in Afghanistan and claimed by many military personnel as being the best military rifle ever.

A new development for HK, the G36 is a true modular weapon system in calibre 5.56x45mm NATO (.223 Remington). Constructed almost entirely of a tough, carbon fibre reinforced polymer material and using a simple, self-regulating gas system, the G36 provides the user with a lightweight weapon that delivers high performance with extremely low maintenance. The barrel of the G36 can be exchanged by unit armouries to create a rifle, carbine, or light support variant using the same common receiver. Exhaustively tested and currently fielded with the German Armed Forces (including the new NATO Rapid Reaction Force), and now on trial by the SAS.

G36 features include:
The low mass of the bolt and ergonomic in-line relationship of the barrel and the buttstock translate to a highly-controllable weapon when fired in fully automatic mode of fire.
The G36 gas system does not direct fouling back into the weapon’s interior like conventional gas operated rifles. This insures reliable operation even after firing more than 15,000 rounds without cleaning. The polymer components can easily be cleaned with water-based cleaning solutions, or even water.
Tough 30-round translucent polymer magazines lock together without magazine clamp. They are 30% lighter than metal magazines and are corrosion proof. 100-round dual drum magazine can also be used in all G36 models.
Ambidextrous safety/selector lever allows for easy actuation without adjusting the firing grip.
The location and function of the G36 operating controls mirror those of the roller-locked HK rifles and MP5 submachine guns, reducing training time and cost.
Ambidextrous cocking lever doubles as forward assist and can be used to silently chamber a round.
Ambidextrous bolt catch button. The bolt catch holds the bolt to rear on the last round fired and can be disabled by the shooter without tools, allowing the bolt to close when the magazine is fired empty.
A variety of trigger groups mechanisms are available for the G36 including the standard “SEF” group, “Navy” trigger group with safe, semi-automatic (3 rounds per trigger squeeze), fully automatic modes of fire and a single-fire trigger.
Detachable folding bipod.
All models use a strong, right side folding buttstock that allows for normal operation and firing when folded.
Chrome-plated, cold hammer forged barrel with 1 in 7 inch twist rifling
Integral mounting rail allows the HK UTL (Universal Tactical Light) to be installed in seconds.
Downward ejection of spent cartridge cases reduces visual signature
G36s operate reliably with frangible training ammunition without special muzzle devices. Blank and safety blank firing devices that use conventional blank ammunition are available as accessories.
G36 weapons are available with two sighting options:
Option 1-the “Export” sight. This single sight system uses a 1.5x optical sight integrated into the detachable carrying handle Backup iron sights are located on the top of the sight and carrying handle..
Option 2-the Dual sighting system. The dual sighting system consists of a 3.5X optical sight topped with electronic red dot sight. Sights are independently adjustable to meet the operational requirements of the user. The dual sight can be powered with ambient light through an open port during daylight periods.

The pictures are mostly of the G36, the SAS are likely to be using the newer G36K, which is quite similar, the most obvious difference being the introduction of a folding stock.



The SA 80 Individual Weapon is the British Army’s Standard combat rifle, made by Enfield/Royal Ordinance and fires NATO standard 5.56 x 45mm ammunition; and has been in service since 1989.

Weight: 4.98kg complete with loaded magazine and optical sight.
Length: 750mm.
Muzzle Velocity: 940mls.
Feed: 30 round magazine.
Effective range: 500m.
Rate of Fire: 610/770 rounds/min.

Not really used by the SAS, because of problems with the rifles’ reliability in adverse conditions.  However they do use it when troopers are having to pose as regular British army troops.
SA80 is the designation for a revolutionary family of assault weapons. The British Army uses the L85 Individual Weapon that replaced the rifle and sub-machine gun, and the L86 Light Support Weapon (LSW) that produces higher volumes of fire and is effective at longer ranges. A standard army infantry section consists of two four-man fire teams armed with SA80s: three IWs and one LSW.

Both weapons have been modified in light of operational experience, and had a major mid-life update in 2002, which resulted in the SA80A2 series – [however despite army claims the ‘new’ SA80 still has reliability issues.]

One new Under slung Grenade Launcher (UGL), designed to be mounted beneath the barrel of the IW, will be issued to each fire team, replacing the Rifle Grenade General Service (RGGS) and 51mm mortar – significantly reducing the ammunition load the infantry section carries, while enhancing its capabilities. The UGL will be able to fire 40mm High Explosive (HE), smoke and illuminating rounds out to a range of 350 m to destroy, obscure or indicate enemy positions.

( 2005


The rifle is fitted with a high-performance optical sight (SUSAT – Sight Unit Small Arms Trilux) of x 4 magnification, which enables the weapon to be used operationally under poor light conditions and is also useful for surveillance. The sight is mounted on a bracket that incorporates range adjustment and zeroing.

The rifle can also be fitted with image-intensifying sights.

Diemaco C8 Carbine

Calibre: 5.56mm NATO round
Capacity: 30 Rounds
Barrel: Hammer Forged
Barrel Length: 36cm
Overall Length: 76cm – 85cm
Trigger: Safe, Semi-Auto, three round fire and Fully Auto
Weight: 2.7kg (empty), 3.2kg (full)
Collapsible Buttstock

The Colt made M4 Carbine was last year replaced by the Canadian firm Diemaco’s, C8 Carbine, it is however ostensibly the same weapon.

Known to have been used by the SAS in all recent operations including Iraq, Kosovo and Afghanistan, the C8 (or the M4 before then) is normally used when a lighter more flexible weapon than the M16 (C7) is required.  For example, when there is an increased likelihood of close quarters fighting, such as in Afghanistan where Taliban ambushes were expected, the M4 can be moved around more quickly by the trooper.

There are four versions of the C8, standard, C8FT (flat top) which allows the addition of a range of different sights, and the C8FTHB (flat top heavy barrel) which means the barrel has an increased thermal mass, allowing it to be used in more intense tactical situations.

There is also a C8 Special Forces Weapon (SF), this is a high accuracy, high modular weapon system designed to meet the needs of special forces , it is highly customisable, and highly reliable.  This includes a heat dissipation feature in the barrel, 3 position buttstock, modular handguard system with rails to attach lasers, illuminators, bipod attachments, sling swivels, and other equipment. It is available in arctic white, desert tan, olive drab or the traditional black and there’s a cleaning kit in the handle grip.

As such it’s a safe bet that this is what the SAS are using.

The C8 can be fitted with converted Heckler and Koch AG36 grenade launcher.


Heckler & Koch 33

From what I can gather the SAS only use this rifle when on body guarding duty; they carry it in the back of their own vehicles and use the version with a retractable stock (the A3) and have it fitted with a laser red dot sight.
They will bring the HK33 out when they need more firepower than that from a handgun and more range than provided by the H&K MPK-PDW which they carry under their jackets,
