The M4-89 is one of the premier fighting rifles we offer. It houses a combat grade barrel, A5 buffer system, Liberty Fighting Trigger, and B5 furniture. At Sons of Liberty Gun Works, we always tell our customers that it's not what a rifle company tells you, it's what they don't tell you. Below you will find the complete specifications of the M4-76. We have built our guns to run through years of hard use, and we have nothing to hide.
