Tactical Flexibility was the innovative force behind the development of the AR-10A4 Special Purpose Rifle line. Whether the rifle application dictates the need for iron sights, red dot or magnified scope, the SPR line is the efficient platform for all sighting options without sacrificing durability or accuracy.
And accuracy is the point, isn't it? At Armalite, we believe it is, so we build all our A4 and A2 rifles with nothing less than a double-lapped barrel for accuracy and chrome line it for corrosion resistance. In the Era of AR Innovation, we will not be outdone.
