Finished 3 Barrel Grenade Launcher

[Davidvaini]

Here is my finished 3 Barrel Grenade Launcher! It fires the preloaded cartridges that I made. The barrels rotate, It has a g36 stock, wood furniture, 1911 Pistol Grip, and a rotating barrel assembly. The barrels are 2 Inch barrels with 1.25" Preloaded cartridges. It fires off a co2 inflator on the field and overall I'm very happy with the outcome.

PICS:








So Plz Tell me what you think!

so freaking nice, clean, well built, nice painted and nice builder ( ) gun is it a long time since i have seen here.

good job.

and vids?

I think its loverly! So you run it off a tire inflator or a cO2 setup? You rotate the barrels manually?
Wait... I'm an idiot, wheres the valve... WTF?

[SpudFarm]

pizlo: it is a cartrige with a burst disk in. he just set them in the end of the barrel and fill them. (i think)

[Davidvaini]

lol pizlo if you look at my preloaded cartridge design you would understand.

Valves are burst disks and actually the lack of weight of the cartridges being removed/fired actually rotates the barrels. I can however rotate the barrels manually if I wanted to.

[pizlo]

Just read that topic, and yes now I understand. You have now added another thing on my to do list. Really Ingenious design. Props.

Soo sweet! How did you get the whole fill mechanism to work, with the rotating barrels, Does the rotation itself lock the fill onto the schrader valve, or do you have to push it in or what?

[blind909]

Awsome job man, one of the nicest, cleanest, and simplest guns on the site. one thing though, where is the co2 inflator? And do you just push the cartrirge onto the inflator, or do the cartriges just lock in place? If you dont mind, I think I will make this sometime this summer(just in a WAY smaller caliber, like say 1/2 inch or 3/4 inch.)

[Davidvaini]

The inflator is currently not attached to the gun. I have been thinking about making some sort of modular setup so I can use it for multiple guns. So for now I am just going to keep it in my hand.

[blind909]

Ok, but when you do get it attached, how will you fill the cartriges?, will it be by the 1911 pistol grip trigger?

[Davidvaini]

You press the inflator to the back of the cartridges. It will either be a front fore grip or a side grip of some kind. Just right now im also making a grenade launcher attachment for my FN2000 so I wanna keep it modular.

[blind909]

Oh, ok.







(message too short)

[Lentamentalisk]

how do you keep the cart from being pushed out when you are filling it? can you give us a picture of the gun with a cart in it?

[Davidvaini]

the pop rivets at the end of the barrels to keep the barrels attacked to the center piece is just high enough to stop the shells. Besides the shells are a nice fit and there is some minor friction that keeps them from sliding forward or backwards... but to answer your question the pop rivets are what hold the shell from being pushed out. they do not block any projectile from being fired though.

niceeee, the wood adds a very nice touch , can you elaborate more on how the rotating part works? Ive already understand it but not the rotating part.
