Iron City Rifleworks is a leader in bolt carrier design and precision machining. These bolts are not lightweight just to save weight: they provide a fine balance between lower weight for better cycling while maintaining enough pass for years of reliable cycling. The C4V is a proprietary version of TiN which provides excellent wear resistance with a hardness of 2600 Vickers. One look at our C4V and you will know this is not your average TiN – it will last for thousands of rounds and barely requires lubricant\u00a0 . With a coefficient of friction 0.4 and only 2 microns thick, this BCG is a major improvement over its competitors.\u00a0 Matched with the Iron City Rifleworks Tacdriver Bolt, made of SAE 930 steel, you can be confident you have the very best.<\/div>\n
