AR-15 Pistol Project

I've been thinking for the past few days that it might be a lot of fun to build an AR-15 pistol. The project would consist of a standard ar lower, a short buffer tube, Hogue grip and forearm, standard upper, 12" barrel, a PWS CQB break, Danial Defence bolt and carrier, MagPul flip up sights and topped off with a Eotech weapons sight. I'm thinking that I will paint the lower, upper and barrel in earth brown. The Hogue grip and forearm would be in gillie tan. I would leave the dust cover black as well as the buffer tube and flip up sights black. With the proper sling I think that this would be a very easy weapon to pack and also be a great back-up for individuals who go out and predator hunt.
