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 our Liberty Fighting Trigger 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-EXO2 is our newest entry level carbine packed with great features.  The Sons of Liberty EXO2 MLOK rail is the best on the market at its price point, it looks great and locks up rock solid.  This rifle has an option for the Vltor A5 buffer system or upgraded charging handle.  Built with the same high quality components that have given us our reputation for guns that never stop running, you can’t beat it at this price.
