I am a newb and would love some design suggestions for a 9mm can. I have some 381-3179 FP's. I am thinking I would probably like to use titanium for the tube and adapter end cap. I will probably use it with subs in a AR SBR.

Thanks.

Here's a link to the completed builds thread

I built one for an SBR , used titanium for the rear cap/blast chamber with a SS first baffle followed by 8 more K baffles. The outer tube , front cap and 8 baffles were all made from 7075 aluminum.
.
We've got thousands out rounds through from heavy sub sonics to hot hot 115 gr ammo and any wear that occurring at all is from cleaning them.

How does this sound... 1.5" OD with 1.35" I'd titanium tube 6" long. With 5 k-baffles giving about 4" and the rest of used as expansion chamber?

It would sound better as 1.375" x 9.00" with 7 to 8 k baffles.
