How the law views sub caliber barrel liners

[fat tony]

I'm in Kanada (edited) , so the laws are obviously different up here, so far Safety Devices like any kind of flare projector/pistol is viewed as a non-firearm, however as soon as a sub caliber adapter is inserted into the flare gun, it becomes equal to a restricted, in the states if it was chambered for a smoothbore shotgun round, I guess it would be considered a Class 3 or NFA weapon. The exception that I could see would be the 12 gauge as there are flares in this caliber obviously. I'm thinking of having a liner made up 'for emergencies', if it was kept separate from the flare gun, it would be damn near impossible to get busted for simply having the liner in your posession. Any thoughts as to the feasability of this project?

[S.S.]

having the liner in your possesion would probably be enough
to prove intent for illegial use. Example, having short pieces of threaded pipe
would probably be overlooked but having caps with holes drilled in them for
that threaded pipe  I am sure would be seen as having bomb making materials
in your possession and I am sure you would be charged as such. My suggestion would
be to stay away from illegal or possibly illegal alterations of any type of device such
as what you are discussing. The jail time would not be worth it.
My 2 cents.

Thanks for the input, there's nothing like 'sober second thought' to put things into perspective.

I was a Law officer for many years, I know The in's and out's
of how things get done to folk!
I became so disgusted with the legal system about 12 years
ago that I just had to get out of that line of work.

Tony - have you ever checked out the MCI Sports site - add a www. and a .com and you are there.  This fellow is in Alaska and may have some information on the legality of his barrel liners/inserts for use in your neck of the woods.  HTH.  Mikey.
