How many have you installed?

I don't know of any machine shops licensed to work on firearms. A barrel attached to an action is considered a firearm...
The story I related was way before firearms licensing...even now all they would need is a PAL
Yeap, and your not supposed to speed or roll stop signs..........
No... the law requires anyone working on a firearm and charging for it requires a federal firearms business license and all that goes with that licensing.
I believe that to be another CFO sponsored initiative with no legislative/judicial substance to back it up for unrestricted guns. A machinist with a local municipal business license & a PAL in his pocket has all the law requires to posses the gun & perform a machining operation.
I'm sure Dakk, Shaun or Gimli will be along to supply the appropriate sections to the act if they do in fact exist.
According to Terminator, the through hole requires opening up to 0.025-0.030" over calibre size. That'd be .333" to .338".
The maker posted about 'em on another forum back in 2012. Backward facing ports (so it'll be really loud when shooting) and "These are CNC machined from 420 or 316 stainless steel & are available with various thread sizes from 9/16 to 20mm." Don't think concentricity will be an issue.
