Loyal readers of MSW and the old 10-8 Forums know that Hilton and I have been longtime fans of Aimpoint red dot sights. Having seen all kinds of optics show up in classes and on the range, along with how they perform through training cycles consisting of fairly high round counts, Aimpoint really has set themselves apart from the rest in terms of reliability and durability. The photo above is of two of about a dozen sights that have been through the wringer for nearly a decade. Attached to agency MP-5 submachine guns, these sights were banged in and out of racks, dropped optic first onto concrete, and abused by patrolmen in just about every way imaginable day in and out. Regardless, they still hold zero to this day and windage and elevation adjustments are accurate. Battery life on the ML2 model is good; we simply change out the DL 1/3N battery once a year. The Comp M4 model lasts even longer at approximately 9 years of use on a single AA battery. Wrap your mind around this: the estimated run time of the Comp M4 exceeds the shelf life of the typical AA battery.
Aimpoint’s new Micro T2 is an excellent choice for a compact and lightweight setup, but the larger windowed Comp series optics are still my favorite.
I have had poor experiences with various EOTech models I have seen students bring to the range, though the newer XPS models appear to be more rugged. There are some advantages to the holographic reticle the EOTech offers, but the auto shut-off feature is a no-go for me.
