The Sons of Liberty Gun Works (SOLGW) M4-EXO2 5.56 NATO Rifle is well-regarded in the firearms community for its quality, reliability, and attention to detail. Here’s a breakdown of what you might expect from this rifle:
Build Quality and Components
Barrel: The 16″ barrel is typically made from high-quality materials like 4150 Chrome Moly Vanadium, with a QPQ (Quench Polish Quench) Nitride finish for enhanced durability and corrosion resistance. The barrel is known for its accuracy and longevity, often featuring a 1:7 twist rate, ideal for stabilizing heavier 5.56 NATO rounds.
Upper and Lower Receivers: SOLGW uses 7075-T6 aluminum for both the upper and lower receivers, ensuring a strong and lightweight platform. The fit between the upper and lower is usually tight, with minimal wobble.
Bolt Carrier Group (BCG): The BCG is often MPI (Magnetic Particle Inspected) and HP (High Pressure) tested, ensuring that it can withstand the high pressures associated with 5.56 NATO rounds. The BCG is typically phosphate-coated, with a properly staked gas key for reliability.
Handguard: The rifle features a free-float M-LOK handguard, providing a solid platform for mounting accessories while not interfering with barrel harmonics, which aids in accuracy.
Trigger: SOLGW usually includes a mil-spec trigger, which is known for being reliable, though some users might find it to be on the heavier side. However, the trigger is smooth with a consistent break.
Performance
Accuracy: The 1:7 twist rate and the 16″ barrel length are optimized for a variety of 5.56 NATO bullet weights, particularly in the 62 to 77 grain range. Users often report consistent accuracy at ranges out to 500 yards.
Reliability: SOLGW rifles are known for their reliability, even under harsh conditions. The rifle’s gas system is tuned for a balance between recoil management and reliability, often using a mid-length gas system which is smoother shooting than a carbine-length system.
Ergonomics: The rifle is designed with user comfort in mind. The controls are intuitive, and the rifle’s balance makes it easy to handle in a variety of shooting positions.
Value
Cost vs. Performance: The M4-EXO2 is priced higher than many entry-level AR-15s, but it offers significant upgrades in terms of materials and construction. For serious shooters, the price is justified by the rifle’s performance and durability.
