The Lanard Shotgun/Air Zone Tripleshot is an older pump action blaster that had a turret of 4 sets of 3 darts, and it was intended to shoot out 3 darts at a time. Though in stock form it was pretty awful, a huge plunger tube and surprisingly strong stock spring gave it massive mod potential, and there are a huge number of examples of modded LSG/AZTS's that can be found with a simple google search. I wanted to do something different in the same vein as my triple rocket Titan - a pump action quad rocket blaster.
Do note that my particular model is specifically a Lanard Shotgun, I don't know how different it is to the similarly coloured Air Zone Triple Shot.
