This 5.56 chambered 18 inch Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and QPQ coated M4 feed ramp extension. If these specs sounds familiar, they should be. These are made by a premier barrel manufacturer for a partner company of ours and are capable of 1 MOA with match grade ammunition.
This barrel features a longer .750” profile dimension necessary for proper installation of the OPS Inc 12th model collar and suppressor.
