The Ward 12.5″ BrainTrust 9mm AR Barrel – [NERD]

The Ward 12.5″ barrel is ideal for sustained, accurate firing in submachine guns, short barreled rifles, or compact pistol caliber carbine builds where precision is paramount.

Weight : 1.628 lbs.  Threads 1/2×28.

The Ward Ring Radial Fluting gives increased surface exchange for heat dissipation during prolonged firing in full auto or semi auto operation.  Despite the increased surface area and rapid heat dissipation, barrel harmonic changes are nonexistent during extensive testing.  The barrel itself is finished off in a QPQ – Life Jacket coating. This is a multi step coating process resulting in a very uniform consistent nitride layer on all Brain Trustbarrels.  [NERD] BrainTrust barrels are hand inspected and test fired for quality control.  Each barrel is individually serialized and date coded using the established Heckler & Koch (HK) method for reference.   Lastly, every single one of our barrels ships with a Certificate of Authenticity matching the unique serialized barrel, signed by [NERD] founders, ensuring this product meets our standards and is worthy of your time and hard earned money.
