They are a government entity, they don't actually have to be there to get paid.Does anyone know if the RCMP tech lab is closed today? Every time I get transfered there the phone just keeps ringing then the call gets dropped.
Can I Cut 16" Midlength Barrel to 11.5"?

GT you make the whole thing sound so sketchy. I suppose in some cases it is. Really though we are not designing a learjet here are we? Just cutting down a rifle BBL.
When mine was done, the gas post was drilled according to one of these "floating around numbers" you mention. It is about the simplest process you can imagine and the person who did it has done many with perfect results. The rifle has run smoothly and consistantly since then on everything from cheap win white box to 30 year old military surplus.
Now having said all that, if i was using my rifle every day in a hostile environment I probably wouldn't go phucking with it. In my world though it goes to the range and kills paper mostly. I would however still trust it in the ever present danger of a zombie attack.

It is sketchy. If you do it for yourself and you know what goes in there, good for you. I am not going to let someone do it unless I know the data myself, and that I told him specifically what to do and he won't deviate from the data. I won't buy a chopped upper either - you cannot see and measure the gas port unless you remove the FSB. I will not trust many of the so-called AR armouror/gunsmith as a matter of fact - I have seen a few of them screwing things up and doing things in their own way even though they were told to do something specifically.
Keep in mind cutting a barrel - recrowning, and drilling gas ports is NOT a M16 armorer task -- that is for a machinist - and ideally one who is both.
Most "gunsmiths" in Canada are not that familiar with the M16FOW - and some also cut corners.
As for gas port diameter - I have the dimensions for the Mk18 and the M4 as well as the M16 rifle. However I dont have anything for the middies - and no one got back to me on the middy shorty port yet.
Another issue with Chrome lined barrels is that you can flake the chrome quite easily while chopping and reaming - so you can drastically impact the service life of your barrel.
Not to mention if the smith does not crown the muzzle right - or re-threads the muzzle off axial - there goes your accuracy potential
(both I've seen in cut jobs in Canada)
I have 2x 10.3 barrels, 2 x 10.5 2 x 11.5 and 1 x 12.5 (in Canada)
so I am sure many many people have barrels too - just keep an eye on the EE.
