Possible Projects 1: 40mm Launcher

Hey Guys,

With the KWA Mac11 threaded barrels delayed for a bit, I have time to show you some of the other things that I have been working on.

I will be starting a series called Possible Projects. These projects will range anywhere from 40mm launchers, like today’s post, to SMG’s and DMR’s. Not all of these projects are items that will become produced, but are more like mental exercises for me. I will try my best to go over such things as back story, design cues and possible problems.

Below is one of my developing projects. Before I do show you, I’d like to give you a bit of back story as to why I came to this idea.

First off, I love 40mm launchers.

Back in 2007, I ran around with a dozen shells from different makers and equipped a m203 on a wooden stand alone frame. I wish I still have pictures of what my buddies eventually dubbed the “B.O.H.I.C.A” (Edit, I found a Photo!)

There was something immensely satisfying about unloading 100+ bb’s onto an unsuspecting squad. One man ambushes were the highlights of my day and rocket lobbing became a natural process for me.

At the end of a skirmish day, I would go home and dissemble and clean each of those shells. There was something tranquil about striping, cleaning and lubing grenades, ranging from Madbull, Classic Army and even a pair of old Mosquito Mold shells as well.

Sadly, due to financial circumstances, college textbooks, the entire lot was sold off bit by bit.

Flash forward a few months and I started hanging out with a different crowd of airsofters, several of whom I would consider my mentors. Digging through their vast armory of rare and classic guns, I fell in love with one little “pistol”. The Elfin Knights Big Horn.

Having the pleasure of using this beauty, I’ve been blown away (hehe) with the ergonomics of the grip angle. She points like an old musket pistol gives a satisfying “shhphunk” as she fires. The grip attaches to a Mosquito Molds 40mm launcher. 

Now, the launcher attachment has been long since discontinued. So I figured… “Hey, the Madbull XM203’s are very similar to the Mosquito Molds launcher, why I can’t I make my own grips…”

Well, here is my version…

The Sabertooth

The design is fairly straight forward. The xm203 launcher is attached to a top rail which interfaces with the unit. The trigger is pulled and connects with the plunger on the madbull launcher. Because the madbull unit already has a safety, it was not necessary to design my own.

The Sabertooth will take real ar-15 grips as well as ones designed for the WA M4 series. The attachment is dubbed the Sabertooth because of how the trigger guard was designed, as well as close name relation to “Big Horn”.

I am not 100% sold on my trigger guard design, so I drew this alternative up as well

After drawing all of this up ( I think I have about 6 hours invested in this so far, from paper concept drawings to these renderings) I am satisfied with drawing up a replacement to the Big Horn, but not satified with it as a product.

The Madbull XM203’s already cost quite a bit, and If this were to be made, it would be too costly for most players. Especially with the AABB and S-thunder alternatives out there.

In all, this was a fun theoretical build, but I don’t see it as a viable product…

Instead of designing an accessory to an existing launcher, I am going to try my hand at design my own hand held launcher.

Back to the drawing board!
