Is this normal or a weak bolt hold open spring?
Second, I noticed that I can pull the trigger and the hammer will drop even when the bolt is not fully in battery. It can be almost 3/4 of an inch from being fully forward. Is this normal? Does the AR-15 have any mechanism to prevent the hammer from dropping until the bolt is completely forward? I am asking because I know that a 1911 will not fire if the slide is not completely forward.
its normal for the catch to release with the butt striking the ground. most guns not just the ar15 will do this.
the bolt has to be fully forward for the firing pin channel to be short enough for the firing pin to strike the primer. it cannot fire, but the hammer can release, until the bolt is fully cammed into place. it is nothing to be concerned about as its normally how the firearm functions in full auto mode. since you missing the full auto sear slector and hammer in a semi auto that prevents it from follow through, its normal for this to occur if you force it to do so.

it will do it with a loaded magazine but not an empty one in place.
