thinking about a project. what barrel lengths are available for ar's? has any one had success with a shorter then 14"? meaning any major problems? heard the only reason the c8 or m4 had a 14" barrel was so a bayonet could be used. i have no c8 experience since at the time of my service only armoured were issued it and obviously no m4's were around. the old vietnam era commando's seem to work well. i'm thinking a barrell between a commando and a c8 maybe 10", 11", 12" ish. is that possible? also any idea were to get the old c7 upper? fixed carrying handle casing deflector flip battle sight. dpms has them but it is over $100 (us export). well thanks in advance.

A 10" barrel would bring the OAL under 26" OAL with the stock collapsed. Isn't legal to build a prohibited firearm. 11 or 12 inch barrel just make the restricted OAL though. I'd be surprised if there are any of 'em in Canada.
Having a bayonet lug or nor is irrelevant. Sterling SMG's took a bayonet.

Huh? AR's are restricted by name, you can make them any length you want, you can buy an 7.5" AR - or build one, if that's what you want. OAL has nothing to do with Prohibition. Chopping a barrel yourself (even chopping a 20 to 18 inches) would create a prohibited firearm, buying one in the length you want can only create a restricted firearm. In fact 10.5/11.5/12 and 12.5 barrels are all available, as well as 7/7.5 and 8. The only thing prohibited about the XM177 and Colt Commando series is that the long solid flash supressor is listed by the BATF as a silencer in the US, and therefore prohibited here (there are a couple of look alikes out there though that are legal). Try Questar, or Wolverine, or ArmsEast for an A2 Upper. ATR would be pleased to provide you with any practical length of barrel your heart desires, in any of an amazing number of calibres. ATR is very experienced in building shorties, so they'll let you know what you need to run as far as buffer weight goes, and they'll give you the correct port dimensions on your barrel.
Less than 26" puts a firearm into restricted territory. Since an AR is already restricted, then it doesn't really matter.
Of course, there's that bit about "altering" a firearm to be less than 26" OAL would make it prohibited....

..likely from the same website that told him all M1 Carbines are restricted (even with a aftermarket barrel).
Problem with the Internet.. and yes, even on this site, is that you need to be wary of what you take as fact. Especially in legal matters.
In Canada an AR can have a 7.5" barrel and "no" stock if you so desire.. it is no more restricted than a 20" AR rifle. It is also not prohibited.

I have seen cutaways and they are internally baffled and as such are in fact a suppressor as they suppress muzzle flash and blast. Not much but they do have an effect.
I'm guessing the legal repros are just straight tubes with holes drilled in the right places, they do look pretty cool though.
They hardly suppress muzzle flash and blast, which has nothing to with suppressing sound BTW. By your definition a standard A2 flash hider would be a prohib device. The XM177 moderator is prohib because it reduces noise 1-2 dB, hardly worth it but the intent was to make it sound more like an M16A1.
