M4 Patrol Rifle SL
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 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 Sprinco Tactical Buffer Springs. We believe in our products and we back them up with a Lifetime Warranty. Our weapons are meant to be used hard and go in harm’s way, they won’t let you down.
Hidden rifles are test fired twice in the shop to ensure proper function
