In the market to build a rifle that's as close to the military-issue M16A4 as possible? Look no further than the Aero Precision Special Edition M16A4 Stripped Lower Receiver. Not only does this rifle offer a great, mil-spec starting point for any clone build, it also includes special markings that are designed to replicate those found on the actual M16A4 rifles issued by the U.S. Military, such as "Property of the USA" and "MOD M16A4." Each lower receiver also features 5.56mm caliber markings and is engraved with a special Aero Precision insignia that doesn't take away from the authenticity of this particular rifle. Another added touch is the inclusion of "Safe/Semi/Burst selector markings, so even if your gun doesn't quite go to 11, at least it can look like it does. The lowers are treated with an all-black finish
Semi Auto Lower with Sear Cut.
