Sharing this from silencer student:

Thought many of you here would want to know this.

PPA will still have 1.372 cups.

I guess if you want cheaper, thicker, heavier tubes with variable from-the-mill bore one can get away with courser threads that hog out a deeper thread form, but also deliver less mechanical advantage when tightening and compressing the stack.  

This is likely driven by market demographics and sales volume and a desire to mix and match test configurations among existing stamps.  Saving $20 in a tube only to have to fit internals or more likely have sloppier fit is a likely trade off.

When cones were mostly skirtless sanding to fit isn’t as big a deal but skirted cones will likely have to be produced for more fit allowance to preclude hand fitting. Centering/nesting features from the blast chamber spacer to the front cap can remediate that concern. But carbon builds up where gasses have places to leak into, so a tighter stack to tube fit that one gets from a bored tube and tight-tolerance cones is still preferable.

Profit and the one-eyed shall be king.

I for one am glad for the change, and having same, common thread on both ends, and a common ID make's it simple for those of us who aren't building cans every other week.

This. This is a dumb move. I’m surprised Mav is going this route.

Well this is idiotic.

I’ve been bitching for a while about how there’s two standards and that we’ve got mouth breathers who insist on 1.355” ID cans...


Guess the mouth breathers use their wallets more often.
