Naastau's blaster

Following his stint as a Jedi hunter in the final year in the Clone Wars, the Mandalorian Supercommando Naastau created a makeshift blaster carbine that used a lightsaber (which Naastau confiscated from a Jedi Knight he'd slain on Mandalore; the saber's containment field projector was then modified to form individual plasma bolts instead of a static blade) installed into a captured DC-15 carbine in place of its barrel and a wire and tube connecting the lightsaber to weapon's power and tibanna compartments.

The lightsaber crystal was yellow, making blaster bolts fired by this contraption yellow in color. This weapon's bolts were twice as powerful as a stock DC-15 blaster carbines, although at the cost ammunition and power capacity.
