The M4-L89 is the premier fighting rifle we offer. It houses our combat grade barrel, A5 buffer system, Liberty Fighting Trigger, Ambi Liberty Charging Handle, ambi Quick Selector, 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-L89. We have built our guns to run through years of hard use, and we have nothing to hide.
