NM Spring Guide

spacerOur National Match Spring Guide improves the consistency and smooth motion of the operating rod which help reduce wear and increase rifle accuracy over the standard stamped GI guide.  Our NM Spring Guides are NOT made from a cut-off stamped GI guide welded to a round drill rod.  These make-shift NM GI guides often have a soft magazine catch caused by the welding and may not be precisely aligned because of poor fixturing.

SpacerOur NM spring guides are produced to the same  specifications as the military’s national match rifles.  The precision is enhanced by making them from one-solid piece of round 8620 tool steel with no welding to cause distortion.  Each is case hardened to  40-45 HRc in an inert gas furnace to help maintain straightness and uniform hardness for  long service. They are finished with a corrosive resistant Mil. Spec. manganese phosphate (aka Parkerized). What makes our NM Spring Guides unique and more  accurate is our precision alignment of the magazine catch  to the guide shaft. This is achieved by turning the .344 diameter shaft from a larger diameter solid rod.   The magazine catch is then precision CNC machined while being located from the guide shaft.  Four flats are milled into .344 shaft body to reduce weight and friction between the spring which adds to the smooth action while precisely guiding the operating rod.

spacerThis product has been field tested in national matches by Dave Ferrante of Heart Mountain Precision Machining, who is a gunsmith and distinguished high-power competitor (email: crookedbrookfarm@yahoo.com). Approximately 4000 rounds have been fired from his match rifle using our spring guide, with no appreciable wear on the catch or shaft.  Mr. Ferrante states, “It’s the finest quality guide out there.”
