I have one of the Bushmaster Carbon 15 with collapsible stock and a EoTech sight with the flip-up rear sight that will co-witness with the EoTech. Bought this for my grandson and he has killed several deer with it and with just over 1200 rounds down the tube. It has functioned perfectly, no issues. This rifle weight is 5.75 lbs, which he can can all day long. Recoil isn't back either.
