Finishing a project

[DeltaKilo]

So, As a few of you know, I had an AR with an identity crisis. An M4-style lower with collapsable stock, 20" Colt SP1 upper. Not a bad rifle, but not entirely one thing or the other.

So, I finally (!) got the last of the components I needed to put together a true M4. Got a Sabre Defence upper receiver today, 16" M4 profile, and got it thrown on. Attached is a picture.

Looks good, but where are your carry handle screws?!

On the other side. I'm looking to swap the carry handle for a rear flip-up and an EOTech holosight.
