Directly descended from the rifles developed by LWRCI� to meet the requirements for the U.S. Army Individual Carbine program the IC-A5 is built for high performance. - The IC-A5 is the latest model in the IC � Individual Carbine series. Customers called for an adjustable gas block and the longer 12� SPR style rail system on the same rifle. We listened- the IC-A5 is designed with a low profile 2 position adjustable gas block allowing the shooter to compensate for running a suppressor with the added benefit of our longer modular rail system. - The upper rail section on the IC-A5 is an aesthetically pleasing special cutback version which allows us to use the low profile gas block and at the same time keep the full 12� modular rails available on the sides and bottom of the hand guards. This IC-A5 brings together features of both the IC Enhanced and the IC-SPR in one package. - Like all IC models the IC-A5 is constructed using the highest quality materials built on our patented self-regulating short-stroke gas piston system machined from materials that belong to the super alloy family of steel alloys most often used in aerospace LWRCI� raises the bar on reliability and ease of maintenance- delivering the highest level of performance. The gas-piston system can be accessed quickly by loosening two thumb screws. - Dual Control fully ambidextrous lower receiver includes bolt catch and release magazine release and fire control access from both sides of the IC-A5. LWRCI� Enhanced Fire Control Group comes standard. Our investment castings are x-rayed for imperfections and nickel-boron coated for a smooth crisp trigger pull with positive reset. - Our IC-A5 uses LWRCI� manufactured- NiCorr treated cold Hammer Forged spiral fluted barrel that are 20% lighter than unfluted barrels of the same diameter. The increased surface area reduces heat � speeds up cooling. Nickel-boron coated bolt carrier delivers unparalleled wear resistance corrosion resistance and permanent lubricity. - The LWRCI� IC-A5 comes complete with LWRCI Skirmish� Back Up Iron Sights Ambidextrous Charging Handle LWRCI� Adjustable Compact Stock Magpul MOE+ Grip and A2 Birdcage flash hider. - LWRCI� ADJUSTABLE COMPACT STOCK - LWRCI� HIGH EFFICIENCY FLASH HIDER - LWRCI� SKIRMISH� BACK UP IRON SIGHTS - LWRCI� ENHANCED FIRE CONTROL GROUP - LWRCI� AMBIDEXTROUS SLING MOUNT - LWRCI� 9� USER-CONFIGURABLE RAIL SYSTEM - LWRCI� AMBIDEXTROUS CHARGING HANDLE - FULLY AMBIDEXTROUS LOWER RECEIVER - LWRCI� SPIRAL FLUTED NICORR TREATED BARREL - ADJUSTABLE 2-POSITION GAS BLOCK - MAGPUL MOE+ GRIP
