5.56×45mm NATO is a rifle cartridge developed in the United States
No, it cannot.
you cant really compare them because M4 is a carbine ( barrel length between a SMG and a rifle), so a compact version of M16 and SA80 is a full length rifle. SA80 has a further effective range I'm going to have to go with the SA80 its by far more accurate, of good design and was used by the elite, how ever the L85A2 is becoming more popular.
Ive seen them fo £30 to £40
The L is a designation for 'Land Forces' and the 98 is the variation type from the SA80, in this case a cadet rifle
The SA80 fires the 5.56x45 mm cartridge. This is one of the smallest calibers for center-fire rifles.
Each has its advantages and disadvantages compared to the other. The SLR fires a more powerful cartridge. In some cases (such as Northern Ireland) it was found to be too powerful. The SA80s cartridge has been found to be underpowered in some instances. The SLR was a variant of the FAL - an extremely reliable rifle. Early SA80s had a lot of teething troubles, to the point where the British government considered replacing them outright with M16s and M4s (they probably would've gone with the Diemaco/Colt Canada C7 and C8s). This was rectified to some extent in 1997 when Heckler & Koch revamped the rifle, creating the L85A2, which has a better service record than the original. The SA80 has a larger basic combat load for ammo - when you consider that most ammo expended in a firefight is used for suppression, the advantage is clear. The SLR has longer range, but most firefights occur within a 300 meter range. The L85/SA80 is shorter, making it advantageous in tight spots. Firer ergonomics were better with the SLR vs. the awkwardly placed selector switch on the L85/SA80.
The assault rifle that can go through almost all elements other than fire is SA80.
The current issue rifle of the British armed forces is the L85-A2 or SA80 (Small Arms 1980s) as it is commonly known. It is a 5.56mm calibre assault rifle. It is a bullpup, meaning that the pistol grip and trigger are in front of the magazine housing. It's magazines hold 30 rounds, and the weapon has two modes of fire; semi automatic and automatic.
No, Since 1985 the British Armed Forces use the SA80 Assault Rifle and its variants.
There are some accurised variants of the M16, SA80, and other 5.56 rifles out there which are designed and used as Designated Marksman rifles, but, in general, the 5.56x45 and .223 Remington cartridges really aren't the ideal choices for a sniper rifle.
Unlike the rest of the British military (who use the SA80) the most common assualt rifle for the SAS is the M4a1 carbine. During the 1990's they used the M16
