Hopefully soon to be LRC-425

Chamber: 4"X21"
Barrel: 2.5"X66"

Flanged Chamber
Dual Ignition
Metered Propane

It has been awhile since I have built one of these but Im taking a semester off from college for work so I got bored. Lets see how four years of college have affected my capabilities. I have full specs, drawings, and 3d models.

Let me know what yall think or if you have any suggestions. The only special thing about this design is the flanged chamber and I'm attempting to make an igniter out of a disposable camera for the first time.

Here is the link to the completed product. It shoots very well and performed beyond my expectations. I know it is not the cleanest design, but keep in mind I built this in an apartment with very limited tools and resources. Enjoy!
