Aluminum Extrusion for Barrel Material

[hwmetzger]

Hello guys, first post here!

I was recently given some heavy aluminum extrusions that I thought would make a fantastic barrel for a higher pressure spud gun. Theyre a 2.5" unequal hex extrusion, 1.75" bore and 10ft long. I believe they're 6063-T6, the thinnest point (between bore and wall) is 3/8", making for a heavy wall at the thinnest point.

My initial thought was a hybrid gun. Any ideas on what sort of pressure I could safely use? And any suggestions for general build style here? I'd hate to use these for a run of the mill gun

wow, nice find, if that was 10mm or 6mm ID

Welcome to the forum!

Burst pressure for that should be around 7000 psi, meaning a high-mix hybrid would definitely be a possibility.

You know what would be awesome, a Wall Gun style launcher.



The octagonal profile of the barrel would really lend itself to the look.

I would want to build a Golden Boy from one, or a BASR. 8)

Love that pic Jack...that is a massive rifle.

Glad to see C&rsenal here, I loved that video with Mae shooting the wall gun.
