Sticks to the best principal - KISS: Keep It Simple Stupid. Will not be turned down for use, as all potato guns are (even though they may be the most high-tech thing out there) And probably the most important part of this instructable, as all instructables by MrTinkerer: 7. Can be used on virtually any airsoft field 6. That will rival any $1000 launcher on the market 5. If you are looking to make an airsoft grenade launcher: 1. I have a fair understanding of all the parts and realize that essentially you're just looking for a rear-load green gas grenade, and a shielded coupler which reduces from 2inches to 1.5 inches. I realize that what you have posted are the exact specifications for a product that will 100% work, though, being unable to acquire such items was difficult, as I am in Canada. I'm using very similar parts, with the exception of a few, namely the grenade, and the shielded coupler. Basically building to the schematics of this instructables, with a few minor differences. Pictures #5-10 are to help visualize the whole mechanism.īuilding one as we speak, this is like 3 years in the making.

Picture #4: *Optional* Install a spring to prevent the trigger from accidentally pressing the valve. When the launcher is collapsed, you want something to hinder the something above from moving forward as a 'safety'. Make sure that when you Extend the launcher the something above (screw, rod, d-ring, etc) has clearance to slide backwards unhindered. Picture #3: Attach something (screw, rod, d-ring, etc) to the bar so that you can grasp it and push the bar forward which will depress the back of the XM PB4 40 mm grenade shell. I used a flat bar so I used 'L' brackets to hold the bar captive. Depending on the material used for the trigger bar/rod find a away to secure it to the control box. Picture #2: Cut the long end of the trigger rod/bar to match the lenght of the control box. shape and bend the tip so that sliding the trigger rod forward will depress the grenade valve. Transfer that measurement to one end of the trigger rod. Picture #1: Measure from the center of the XM PB4 grenade valve (the silver circle) to the top of the control box. I used a a 1/8 thick by 3/4 inch wide aluminum bar. Here is a video of the locking mechanism. I think the trouble is people are trying to make it more complex than it really is.

Edit: People still don't get how to make locking mechanism. put a layer of fiberglass, felt or duct tape to make sure the plastic does not come off or shift (see the green square in picture 2). Glue the strip of plastic to the side of the tube in such a way that when the launcher is extended the screw goes into the hole in the plastic. Drill a hole on one end for the screw in STEP 6 to go in to. Look around and use creativity and imagination. Look around your house/environment for a strip of plastic at least 1/8 of an inch thick and about 3 inches long. EDIT: Picture 2 & 3 - The Locking mechanism (13 seconds into the video) This is a strip of plastic glued to the side of the launcher. Once the epoxy cures, paint your choice of colors. I epoxied it to the top and reenforced with more fiberglass and felt. I used sections of a 1 inch square pine dowel. an elegant weapon for a more civilized age.įigure a way to make some sort of control box on top of the outer tube.

The fire control system can be used to program PPHE grenades to air burst above the target - ideal for engaging troops sheltering behind cover. A AN/PWG-1 Lightweight Video Sight, linked to a ballistic computer and laser rangefinder, enables the operator to identify and accurately engage targets, day or night. The MK47 features an integrated computer assisted fire control systems and programmable ammunition. It is planned to eventually replace the MK19 grenade launcher with the new MK47. The MK47 is an advanced 40mm grenade launcher in use with US Special Operations Forces (SOF).
