The hammer forging process work hardens the steel, making it more durable. In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability.

This A2 profile barrel is Mil-spec phosphate coated, High Pressure tested and Magnetic Particle inspected. The barrel is finished with a .750" diameter low-profile gas block, PSA 15" Lightweight M-Lok Free Float Rail, and an A2 flash hider.

What makes this a precision rifle?

BEST ANSWER: The 20” FN barrel plus the nib 2-stage trigger. These two items together will make this a tack driver. Also with the tool craft NIB BCG it will be super smooth running.
