Worked a little more on starting construction of the pump grip for this Longstrike. So far the mechanism is pushing back both pins of the Longstrike's priming Handle evenly, which is successfully completing the prime. With the spring upgrade from the OMW parts, the weak boltsled was unable to prime this blaster with one hand, which is why the pump action is necessary. To cover up and build the pump grip, I've used parts from the Lonstrike's barrel extension. It's looking good!
