Pretty Sparks

This is Marv cutting a piece of titanium tubing to create an expansion chamber for his home-built solvent-trap suppressor for his SBR.

The choice of titanium is to be both a spacer for the first expansion chamber and as a liner to protect the aluminum body from the effects of the muzzle blast from a 10.5" barrel and 5.56x45mm ammo.

For the nitpickers, yes he's got an approved Form 1 for both the carbine and this sound snuffer.


  1. Careful how hot he gets that stuff when cutting it. It takes some doing to get it there but once it catches fire there's not much putting it out.

    1. Surprisingly, we knew that. He did it in little nibbles.
