The IC-SPR from LWRC was originally designed to meet any challenge it ran across and meet the rigorous standards of the professional user. The Individual Carbine series stands out with its use of a durable short-stroke gas piston system. this gas piston system comes with an adjustable gas block so that the user can tune their rifle for adverse conditions and keep the rifle running when the going gets tough. The heart of the performance of this rifle is the NiCorr barrel that is meant to give this rifle great shooting performance and the unique spiral fluting reduces the weight without losing that great shooting potential. The lower of this rifle is ambidextrous to better work with a variety of shooters and shooting positions while maintain the controls of the AR-15 that you know and love. If you are looking for an advanced and good shooting piston driven AR-15 Look no further then the LWRC IC-A5.
