According to an e-mail obtained by Soldier Systems, EOTech is starting its line-up changes for 2015. Two new sights have been announced, the 518 and 558, both of which use AA batteries. Both sights include the Q/D mounts common to the EXPS line.
With the introduction of the 518 and 558, the 556, 553BLK, 553TAN, 516, and 517 sights are being discontinued. Also discontinued is the Zombie Stopper line (with the radioactive-sign reticle).
As a bonus for buyers, all MAP restrictions on the now discontinued models have been removed as of 12/03. Those looking for a great bargain on sights should be on the hunt now.
