Faxon Firearms 15B22A7R16NGQ5RNP3: Faxon\'s Gunner profile combines the durability of the Gov\'t profile with the weight savings and maneuverability of the Pencil profile. The Gunner profile brings the balance of the rifle back towards the shooter\'s body, limiting fatigue, and allowing for shooting, training, or hunting all day long. The Match Series starts with 416-R in 5rd rifling. 5rd is a hybrid rifling, with lands opposite grooves and reduced sharp angles that reduces jacket deformation increasing velocity and easy cleaning. The barrels are Nitride treated inside and out, locking in the bore, improving barrel life, and keeping the elements at bay. The extension is coated in Nickel Teflon which maintains dry lubricity, corrosion resistance, and tightens up fit between the extension and receiver.
