Hope this helps! I will definitely be ordering more parts from Huckleberry Arm in the future. This carry handle is 5 and its overall base is 7.125 long. It comes equipped with a built-in dual aperture rear flip-up sight with adjustable windage and elevation settings. When I talked to Aero Precision, I was worried about Alignment issues with a 20 Inch Barrel, they stated to turn the front sight post 4-6 clicks downward when zeroing in for perfect alignment. AR Detachable Carry handle with A2 design is made with Aircraft grade aluminum and steel for strength and durability. Needed it to complete a Aero Precision M16A4 build, and it turned out great! Works great with a F Marked Front Sight Base. Huckleberry Arms was one of the few places that had this carry handle in stock. Carry handle had the square forge code and was in perfect condition. Update: I received the product in just 4 days and it came as advertised. They were also the only website I could find that had the Aero carry handles in stock. I received a call that my card info did not match up with the shipping address and the gentleman on the phone was extremely polite and helpful. The customer service here at Huckleberry Arms is great and they shipped my order very quickly. Chambered in 5.56 NATO, with a 1/7 twist, M4 barrel extension, and a rifle-length gas system.
