My Law Rocket with back breech

[bakrauf]

This is my Tank main weapon. I made it out of 1 1/2 PVC pipe. I then took a coupling and sanded it doan to make a really tight fit. I will post pics and explain them. I wont tell you exactly how to make it becaue I dont want sued. I did this by trial and error. But I can Load an unload htis thing in seconds. It uses a standard 12 gram CO2 cartridge.

Another shot.. notice the unpainted area wher the breech slides open.




A Nerf Football tank buster



Open says me!!!!!

Putting the nerf inthe tube



Its kind of forward



But all you do is pull it backa few inches




Slide the Breech back and BOOOOM FIRE!!!! IF i want to uunload this thing I simply open it up and take out the nerf. Much easier than a regular law..THere seems to be no loss of power at all

Sweet ! What kind of distance are you getting ? How many launches out of the 12g cartridge ? Kind of the same idea here only using multiple tubes and switch system when I can figure it out... ...PG

[bakrauf]

You get only one shot per 12 gram..Of course you get shoot down as the pipe gets colder but the first shot goes at least 300 feet and drops from there. Its pretty damn accurate to. I could use regular air buy hoosing it up with a renmote but I cant regulate it as well. Plus most fields only allow the 12 gram.

Do you have the specs on it?

[blindspot]

1.5" PVC? Most Nerfs fit into 2" PVC, not 1.5"
Otherwise, looks like a great basic ball valve launcher. I would guess about 6" of 3/4" or 1" iron pipe, with a 1" or 3/4" ball vavle.... your standard 12 gram changer rammed and JBwelded into a 1/2" reducer fitting... and a 1.5" (or 2"?) to 1" or 3/4" bushing. Good work! Especially on the breachload. I bet you had a dandy of a time sanding the inside of that coupler down to get it to fit just right.

Here is another breechload design by greywolf on "That forum which shall remain nameless", plus other launchers in this thread:

(scroll down to the "orange" looking launcher)

Yes I stand corrected... it is 2 inch.. I tired 1 .5 and it was too small.. IT was a pain inthe arse to sand that conneter. To much and your screwed but it shoots great.

Very nice! I am thinking about making one.

Hey how big did you cut the breach hole?

[bakrauf]

Cut it just big enough to get the nerf in and small enough to be coverd by the coupler

[caboose]

Yeah he already made it. Cause i received it.
