Quest 4B bolt kit Item details: This enhanced firing assembly was created with the help of a few other dedicated players in order to bring the classic Quest marker line up to current day bolt technology. Compared to the stock bolt parts, the entire assembly has been stripped down to basics and redesigned from the ground-up. The number of problems we fixed is understated by the level of quality we are able to provide for such an intricate product.
