Im new to the Ar15's. I just bought a Bushmaster M4A3 and an Eotech 511. Im wanting to mount the Eotech on my carry handle (in front of the carry handle) to co-witness my standard iron sights. What mount should I use?
I also thought about removing the carry handle and mounting the eotech directly on the top (no raisers), also adding the ARMS #40 flip up rear. Will this co-witness well? Will I have to purchase the taller front sight post when using the ARMS #40? Sorry it seams like so many questions to ask. Just trying to find a good setup. I would really appriciate some info, answers, or tips. Thanks for your time guys!
