Hand Guard is WC's Trim rail. It's a little more slender than the Yankee Hill I have installed on my other AR-15, but it's very comfortable to shoot and heat is not a problem. It is easy to attach accessories to, but you have to buy an attachment accessory rail to do so.
You gonna have to bring that by the shop so we can get a better look at it. Looks really good so far. Call and get Lanny to bring his latest build so we can compare.
The Aimpoint PRO is mounted to a Rock River Arms tactical mount assembly that contains an A2 rear sight. Because of my 60 year old stiff neck, the higher location of the Aimpoint is more comfortable for me.
