CongratulaAons!InpurchasingtheLWRCIRapidEngagementPrecisionRifle,younowhave themost capable7.62x51mmNATOsemi‐automa3crifleintheworld.LWRCI’s goal was todesignanddeliverarifle thatwas more reliable,userfriendlyandwhileas accurateas a custombolt‐ac3onsniper rifle. The system is user configurable for day or night use. The systemwasdesignedtousemul3pleupper receivergroupsfromashort12.7”barreledupper tothe20”Sniperupper.

Thesystem is loosely based on theStoner AR architecture topreservethefeel andmusclememoryassociatedwithrifles basedontheStonerdesign. That is where the familiarityends.Thebarrel toreceiverinterfaceisalmostthree3mes more robustthananyotherrifle. Barrelsare cold‐rotary hammer forged over a precisionmandrel and boast perfect bores that areconsistent in concentricity 0.0002”. The barrel is finishedmachined inprofiles tomaximizeaccuracyandminimizetheadverseeffects ofbarrelwhipandharmonics.Atargetcrownis usedtomaximize hit probability. Thebarrel is finished intheNiCorr surfaceconversionprocess.NiCorr is harderthanchromeandoffersalowerco‐efficientoffric3onaddingtobarrel lifeandmuzzlevelocity. Itmakesthebarrels easier tocleanas theydonotfoul withcopperas readilyandare virtually impervioustocorrosion. Thematerial chosenforthebarrel isthesameusedontheM2.50calibermachinegun.

Theweapon features a lee sidenon‐reciproca3ng charging handlewith integrated forwardassist. Thisallowstheuser tooperatetheac3onwithoutcheekweldandthus keepeyes ontarget.
