At Motor City 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 are meant to be used hard and go in harm’s way, they won’t let you down. SOLGW – M4-76

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

The M4-76 is the newest addition to the Liberty Series, featuring our brand-new M76 Wedge Lock Rail.  The M76 features a Steel Barrel nut and rock-solid Wedge Lock locking system. The M4-76 also features our Liberty Fighting Trigger, Raptor-LT Ambi Charging Handle, and awesome Vltor A5 buffer system, for the Ultimate Fighting Rifle.  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-SL. We have built our guns to run through years of hard use, and we have nothing to SOLGW – M4-76 hide.
