AR, XCR, without gas port? (looking for barrel with integral lugs/barrel extension)

[H Wally]

I'm looking for a style of barrel that uses the AR style barrel extension or otherwise has a method of the bolt locking directly to the barrel (instead of receiver) similarly to the AR and XCR. Furthermore, since I'd like this to be a bolt action rifle, I'd prefer it to not be ported. Is there anything already on the market like this at the moment?





To provide some background, the need for the barrel is for a rifle that has an easily removed barrel for compact storage and does not require extensive use of a lathe or mill to make as barrel and bolt head are pre-made.


Edit: Found someone with exactly what I'm thinking and a breakdown:

I suppose in further thought press fitting a collar over the gas port would be a reasonable workaround, but I don't at all like the concept of having a pocket in the barrel to collect dirt, lead and moisture.

Since it doesn't seem like these are commonly available, is it viable to either A) plug a port or B) pull one from a line before it's drilled? Any common manufacturers that might do this? I'm very unfamiliar with black guns and the industry so I'm not even sure who would be worth contacting first.

Bolt-action ARs are all the rage in England and other dictatorships. Many of the manual action guns that lock in to a barrel extension are of European origin, due to having limits on the number of guns a person may own, but no limit on the number of barrels one can own. The Mauser M03 is an example as well as Merkel, Blaser and others.

In Canada, there is virtually zero demand for such a thing as AR's are restricted regardless. As for rifles like the M03, you can buy a Remington 700 with excellent optics, or 4 to 5 Savage Axis' for the cost of each M03 barrel.

Having said that, there is no reason why you cannot make a straight pull rifle using all AR parts, minus the actual receiver components of course.

Yep - that's my thought - something of a poor man's version of the EDM arms windrunner series. Since AR's are common it's all the more reason why they'd make a suitable base point for parts that wouldn't impact the classification. Preferably the build would use XCR components because they're non-restricted so there wouldn't be any issues with it being ruled restricted as a variant, but there isn't really much of an aftermarket for XCR barrels and parts... so it's back to AR's...... unless there are other guns out there using the barrel extension system? (It'd be very convenient to have a ready made barrel and bolt assembly)

I see your concern but I do not think it is valid. If the gun is not semi-automatic, and does not use either the upper or lower of an AR 15, and does not outwardly resemble an AR15, it would be a far stretch to call it a variant. Using those parts is by far your best bet, as they are both affordable and readily available. Everything else is both too expensive and not readily available.

Installing an AR barrel extension on a barrel is essentially the same as fitting a barrel to a receiver.
A barrel extension can be easily fitted to a take-off 110 Savage .223 barrel, for example. Done carefully, it is not even necessary to use a chambering reamer.
Now there is a catch to using an AR barrel extension and bolt to make a bolt action rifle - there has to be a provision incorporated to prevent the rifle from firing until the bolt is closed and locked.

My thought is that the easiest method would be to use the barrel, extension and bolt head from an existing design since that would remove 95% of the complex machining and heat treating. My concern is that the CFC would likely take offense to using any internal components related to the AR family, no matter how small, if they're directly related to the bolt. Since getting written explained statements out of them is like pulling teeth I'm trying to design something that's hard to say no to.

Agreed on all counts - since I currently don't have frequent access to any quality machining tools I'm looking for pre-made products that can simply be assembled or bought assembled, since I can't do any machining of my own right now. The benefit to a barrel extension is that it allows the barrel to be removed and put back on with minimal effort, which interests me as I'd like a small package rifle.

As far as avoiding firing out of battery I've got a couple designs for both ensuring the barrel is in place and the bolt is locked before allowing the rifle to fire.
