[QUOTE="Greyfox, post: 1105108, member: 10291"] The effect of the fit between the lower and upper and the "rattle" could have the same effect as if your bolt action had movement in the stock. Most AR's have some degree of movement, if not when new, after repeated take downs. It's no big deal if there is a some movement since it can be easily shimmed with one of the many types of small shims, or cam pins designed to eliminate it. I'm sure 90% of AR shooters would never see the effect of the looseness typically encountered. For precision work, it becomes more critical and I would simply place a spacer under the rear contact point. With cheap plastic lowers I would be more attentive to the fit of the trigger group, safety, and other interfaces that effect function. iMO. [/QUOTE]
