At Sons of Liberty Gun Works we believe in Quality Mil-Spec or better parts. We believe there is no substitute for quality and that your gun should be built right the first time, ready for hard use right out of the box. We believe a quality Bolt Carrier Group and a quality, accurate and long lasting barrel are the heart of a Combat Grade weapon. We believe in properly tuned weapons using the correct gas system length and quality buffer system components such as the Vltor A5 system and Sprinco Tactical Buffer Springs. We believe in our products and we back them up with a Lifetime Warranty. Our weapons our meant to be used hard and go in harm’s way, they won’t let you down.

All rifles are test fired twice in shop to ensure proper function.

The M4-76 is our premier fighting rifle, featuring a 16″ combat grade barrel, A5 buffer system, Liberty Fighting Trigger, and B5 furniture. 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 M4-76.
