The M6A3 has been replaced by an improved version, the M6A5.

The LWRCI™ M6A3™ features our midlength short-stroke gas piston system that is the perfect blend of tactical carbine and sniper-capable rifle. The midlength operating system’s softer recoil allows for faster return-to-target and follow-up shots.

The M6A3™ rifle features our adjustable gas system. Four positions - (O- Off, S-Suppressed, N-Normal, A-Adverse), which allow for optimum performance in any situation.

Designed with optics in mind, the M6A3™ rifle is perfectly suited to accept a red dot sight or a high-powered scope. It features an integrated flip-down front sight and patented ARM-R free-float rail system. The easily removable top platform gives quick access to the barrel and piston system and reinstalls in seconds with no tools required.

The 18” version is our DMR Model (Designated Marksman Rifle). It features all of the features found on the standard M6A3, but it is also equipped with a Geissele two-stage trigger. All other M6A3™ rifles come standard with the Enhanced Fire Control Group.

The new M6A3™ rifle is the perfect all-purpose weapon for the modern warfighter or law enforcement professional.
