One of the things I wanted most from the Demolisher was a detachable rocket launcher, because I like underbarrel grenade launchers. Sadly the stock Demolisher rocket launcher is permanently integrated, so I did it myself.The cut I made to separate the underbarrel rocket launcher was quite clean and straight, the only problem being the open space left in the shell. The other main issue now is that the bottom flywheel is exposed, though with the rocket launcher or the rail attached it's not a huge problem, though I may fill some of the gaps with cardboard.This is the rocket launcher module. The pieces of wood fit into the gaps in the Demo.The rocket launcher is secured into the Demo using 4 screws, two on each side. They go into the blocks of wood which are secured to the rocket launcher, making the Demo basically back to what it was.As you can see, with the rocket launcher reattached, from a distance it looks practically stock.For when the rocket launcher is not in use on the Demo, I made a tactical rail that slots right in, partly to help fill the shell gap and also for comfort.Like the rocket launcher, it's held in by 4 screws, two on each side. It shares the two front screws with the rocket launcher, but the rear two screws are different.With the Retaliator's foregrip attached. I think it looks quite good, and is fairly comfortable to use. It also works with an angled foregrip. Moving the tac rail a few centimetres forward may make foregrips more comfortable to hold, though I personally don't like the look of grips so far forward.Now a question you'll probably ask is "Doesn't replacing the rocket launcher with a tac rail basically make it a Stryfe?"Functionally, yes, since they're both clip (mag) fed semi auto blasters. Sure the Demolisher is physically a little different internally as well as larger, but they both do the same thing.However the Demolisher has 2 more tactical rails (including the 2 rails I added) compared to the Stryfe, and has a different aesthetic. To me the Stryfe has a pistol/PDW/SMG type aesthetic without barrel extensions, while the Demolisher has a carbine/assault rifle aesthetic.The main reason I made the rocket launcher to be detachable was to make it into a standalone blaster using a Barricade body, of which I have several spare. Neither the trigger nor the battery box do anything useful.The rocket launcher is secured to the Barricade body again with 4 screws, however these screws are totally different to the ones that attach to the Demolisher. Though difficult to see side on, there are two screw heads present on either side of the Barricade body, right behind the rocket launcher.One of the main draws for using a Barricade body was the ability to attach a stock and sight. While any sight is pretty useless, a Demolisher stock is extremely useful as it allows the storage of an extra rocket. A stock is also useful for bracing the rocket launcher, since it's pump to fire.The Barricade shell is just empty and hollowed out for the rocket launcher to slot in.This project is not yet complete. The final part of this project involves using tactical rail clips, probably sourced from Slydev, to allow the attaching of the rocket launcher to any blaster with a long enough tac rail. While more tacticool than practical, having an underslung rocket/grenade launcher is something I've wanted to make for a long time.
