LWRC INTERNATIONAL INTRODUCTION Thank you for purchasing the LWRCI Rapid Engagement Precision Rifle (R.E.P.R.). LWRCI’s goal with the R.E.P.R. was to design and deliver a self-loading rifle that is more reliable, user friendly, and has accuracy comparable to a bolt-action sniper rifle. R.E.P.R. is loosely based on the proven Stoner AR architecture of modular upper and lower receiver groups. Rapidly interchangeable Upper Receiver Groups from the short R.E.P.R. 12 (12.7” barrel) to the R.E.P.R.
R.E.P.R. MANUAL enhance accuracy. Finally the barrel is finished with the NiCorrtm surface conversion process both internally and externally. As a surface conversion, NiCorrtm does not require micro-relief of the bore with hard chrome nor does it suffer galling and flaking at high temperature. It is also harder/more wear resistant, has a lower coefficient of friction, holds structural integrity at higher temperatures, and is more resistant to corrosion.
