The M-15 is introduced as direct competition with Colt’s trademarked AR-15. Mr. Mark Westrom purchases Armalite from Eagle Arms where he continued to produce the Eagle Arms EA-15 rifle. Product focus turned toward high-grade target rifles. Shortly thereafter, a design for a .308-caliber AR-10 type rifle was initiated and designated the M-10. Westrom purchased all rights to the Armalite trademark in 1995, and production of Armalite rifles resumed in Illinois. The planned M-10 rifle series was designated the AR-10B series and was developed using unusual reliance on computer design and simulation. Armalite drastically expands the AR-10 line with new featured rifles and carbines, including the AR-10 SuperSASS™, which features an adjustable gas system to accommodate suppressed and unsuppressed fire.
