The IC-A5 is designed with a low profile 2 position adjustable gas block allowing the shooter to compensate for running a suppressor with a longer modular rail system. Its 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. It is constructed using the highest quality materials, built on a patented self-regulating short-stroke gas piston system. They machined from materials that belong to the super alloy family of steel alloys most often used in aerospace. The gas-piston system can be accessed quickly by loosening two thumb screws. Its dual control fully ambidextrous lower receiver includes bolt catch and release, magazine release and fire control access from both sides of the IC-A5. This rifle features an NiCorr treated cold hammer forged spiral fluted barrel that is 20 percent lighter and increased surface area that reduces heat speeds up cooling. The Nickel-boron coated bolt carrier delivers unparalleled wear resistance, corrosion resistance and permanent lubricity. Included is a Skirmish back up iron sights, ambidextrous charging handle, adjustable compact stock, Magpul1 MOE+ Grip, and LWRCI High Efficiency 4-Prong Flash Hider.
