The M4-76 is the newest addition to the Liberty Series, featuring our brand new M76 Wedge Lock Rail. The M76 features a Steel Barrel nut and rock solid Wedge Lock locking system. The M4-76 also features our Liberty Fighting Trigger, and awesome Vltor A5 buffer system, for the Ultimate Fighting Rifle. At Sons of Liberty Gun Works we always tell our customers, its not what a rifle company tells you, it's what they don't tell you. Below you will find the complete specifications on the M4-SL. We have built our guns to run through years of hard use, and we have nothing to hide.
