Product Description

Here is one of our favorite custom builds. We decided to try and rebuild the old school C7 M-16A1 Carbine These are using a true M-4 carbine barrel with a 1/7 twist. The barrel is made of 41V50 steel and the chamber/bore is chrome lined. We use a Extended A2 Bird cage flash hider on it then pin and weld to complete compliance with the 16" OAL length rule. By doing so this is not a NFA/SBR item. C7 Upper receiver is black finished. Handguards are single wall Mil-Spec.

The 80's and 90's saw major changes to the modern duty rifles carried by US forces. Most notable the adoption of the carbine gas system and shorter barrel over the longer rifles. These advancements where directly related to the requests from special forces units such as SOF-D, Army Rangers, and Navy SEALs. The 723 and 727 were the precursor to the modern M4 we all know today.
