What do you guys recommend for BUIS. I like the idea of the choped carry handle LMT's, but not sure if I want the bulk. I want a rear sight that can be used as a stand alone sight, as it will be my new primary sight for a good while. To both get very familiar with it, and to allow me to save money for a optic I want. My concern with the LMT is the bulk, my concern with flip up sights is the hinge point. While I might not be going to any classes any time immediatly soon I do want the BUIS to be a durable one. So what do you guys recommend?
