AC-556

Template:Wikify-date The Ruger Mini 14 or AC556 was supplied to the Royal Ulster Constabulary in 1979 as a weapon for its Special Patrol Groups, Special Operations (E Services) and exposed border police stations and units. It came with 15 round and 30 round magazines, wooden stock and flash eliminator. It had simple iron sights, sling and was employed with two settings as to it's rate of fire, single shot and burst of three rounds.

In the main it was a reliable replacement for the Sterling 9mm sub machine gun in more open and country areas, the M1 Carbine which although lightweight had zero penetration or range and presented less of a weight than the UK modified FN or SLR rifle assault rifles whilst retaining an acceptable hitting power and range. In situations such as those presented by ambush of security forces in rural Northern Ireland the ability to respond with repeated and quick fire was far more important than accuracy. Local terrorists experiencing any measure of opposition from ambushed police would quickly withdraw hence earning their nickname amougst local people as "I Run Away" (IRA).

One of the characteristics of the 5.56mm round was its habit of shattering on impact with human targets. The round was as per NATO 5.56mm lead with a copper jacket but its high velocity (apparently more in the AC556 version than the AR15 rifle) caused the round to shatter. Another less desireable problem was the habit of the round to become separated from the cartridge at the top of the magazine when said magazine was exposed to ordinary handling. This may have been because of the shape of the magazine and reciever but was never really established.

There is no doubt that the Ruger Mini 14 or AC556 contributed greatly to the saving of lives in the Royal Ulster Constabulary in the early 1980's and together with the handgun that Ruger suppiled, a 2 and 1/2" barrelled .357mm Magnum Revolver provided the core duty and off duty weapons of the force.

Neither are a classic but both provided a period of functional and robust defence against a pernicious and cowardly enemy.
