A common issue with standard firing pins is that they do not protrude far enough to reliably ignite 7.62x39 primers. This Premier 7.62x39 BCG features a bolt assembly with a shortened bolt tail, allowing the standard firing pin to protrude farther than it would with a standard bolt, thus eliminating this issue. There's no need for heavier hammer springs to ensure reliable ignition.
