  • Jacob Grey Fireams has finally did what others have only dreamed of doing. With an extensive knowledge of specialized parts in the aerospace industry, Jacob Grey has used that experience to manufacture an extractor that will put up with the enormous pressure and force of the 7.62x39 round . As AR enthusiasts are only too aware, the AK round was never meant for the AR-15. The standard .223 REM round commonly used, while adequate, was never a full match against a Soviet manufactured 7.62x39 steel cases round. With far superior ballistics, range, and power. The 7.63x39 would exert nothing but stress on the standard bolt found in today's modern AR. A common problem has always been the round's ability to crack and eventually break the steel extractor. Even the strongest hardest steel eventually gives way to the force and power behind this round. With decades of experience manufacturing flyaway parts for today's modern fighter jets, F-16 Fighting Falcon, F-35 Lightning II to name a few. With over 40,000 LBS of titanium cut each year, Jacob Grey has taken that knowledge and applied it to the one blaring problem with the AR-15 extractor. The result is the strongest most durable 7.62x39 extractor on the market today. Designed not only to grab the round at the precise moment needed, but a deep enough face to pull a swollen steel cased 7.62 round from the barrel without slipping and extracting each time. Made from high grade 6AL4V Titanium. Individually cut. The perfect upgrade to any 7.62,AR build or rifle.
