The S1A3 is a Bull pup arranged rifle designed around the forgotten British 6.25x43mm rifle cartridge. During a series of trials it was identified as being close to the optimum for an infantry round. The 6.25mm round offers performance equal to the larger 7.62 NATO round out to about 600m but with recoil and ammo weight very close to 5.56mm rounds.
The S1A3 uses a much improved version of the SA80 mechanism offering rock solid reliability and performance (a must in the harsh conditions found all over Crookfur), the bull pup design allows for a greatly reduced length making the S1A3 perfect for airborne or mechanised infantry. Included in the basic package is a 4x scope based on the British SUSAT, this is mounted on integral weaver rails allowing alternative sights to be used if desired.
Unsure if this a joke or not
