The Modern Hunter is an exceptional rifle from the precision gun shop Alberta Tactical Rifle Supply. Based in Calgary, ATRS started in 1997 and has built a business producing premium AR-15s and long range bolt guns. In 2012, they started tinkering with the idea of designing a direct impingement semi-auto rifle that used features from both their business lines. Three years later, after a variety of concepts and prototypes, they settled on the Modern Hunter.
While at first glance it may well look like an AR-10, but the Modern Hunter has achieved a non-restricted status from the RCMP inspection lab. It is a completely unique rifle without any lineage or compatibility to AR-15 uppers and lowers.
In Canada, all AR-15s are restricted by name. Regardless of barrel length, regardless of name or designation. So any gun that separates into an upper and lower and can be attached to an AR-15 upper or lower is listed as a variant. The RCMP test lab has a whole range of variables they use to determine a firearm's classification, but the upper and lower problem is important here specifically. If either component can be convinced or forced to fit the opposite AR-15 component, it will be likely be classified as an AR-15.

This rifle is magazine fed, uses the direct impingement gas system, and features a rotating locking bolt that recoils on a buffer and spring system. If you described that to a knowledgeable American shooter they'd say you're talking about an AR-15.
But the Modern Hunter differs from the AR in some key ways. A side-folding charging handle, a proprietary gas block, and a proprietary bolt all integrate into the unique upper and lower system that separates the Modern Hunter from conventional AR-15s.

The Modern Hunter is a semi-custom rifle. There isn't a single style of factory model rolling off the production line, but a selection of different configurations being offered. ATRS offers a wide variety of barrels and furniture to assemble a number of unique builds.
One of the featured options is the Proof Research Carbon Fiber Barrel that replaces ATRS's match stainless barrel. Proof Research takes a 416R stainless steel barrel blank, then dramatically reduces the profile between the muzzle and the chamber to form an axle shaped length with only a small portion of full profile barrel at each end. Then they wrap the slimmed down center length in a proprietary carbon fiber until its flush with the original profile. The carbon fiber is much lighter than the steel its replacing, and its better at dissipating heat too. This labour intensive process means that the barrels are only offered in 18.6" and 20" lengths, while the regular stainless barrels can also be had in 22" and 24" lengths with a variety of profiles.

My review rifle had a 20" stainless barrel, a JP Enterprises hand-guard, a Magpul PRS adjustable stock, an Atlas bipod, and a hefty Nightforce 5-20x50 on top. On the scale it weighed in at a full 14.5lbs. Maybe heavy for an AR, but still manageable for a precision semi-auto rifle.
In field conditions I was shooting groups just under 2MOA with Privi Partisan and Federal Gold Medal, with my best 5 shot group coming from Fiocchi 180grain Exacta at 1.28 MOA. I am confident that an established reloader shooting from bench rest could produce sub-MOA groups after working up a load.

The first run of 75 rifles have already been sold, and are slated to arrive in their owners hands in the first quarter of 2015. A second and third batch are currently planned for summer and fall, but as a small shop ATRS is currently aiming for under 100 rifles in each production cycle.

If you're looking for chambering closer to the classic AR-15, then you'll have to wait for the next evolution of the platform. ATRS has confirmed they are already planning a Modern Varminter and a Modern Magnum. Between their history with .223 AR-15 rifles and having already produced the Modern Hunter, a small caliber variant should be a logical step. Likely the longest part of that process will be the RCMP inspection lab's process of FRT classification. The Modern Magnum however will require up scaling of all their components, and could be another 3 years or more in the making. ATRS builds bolt guns in .50BMG, .408 Cheytac and .338 Lapua, but the Modern Magnum will be a first for them.

But how exactly did this rifle qualify as non-restricted? The inspection report is surprisingly detailed.
The RCMP compared the Modern Hunter to an early model AR-10, and a late model Armalite AR-10, and noted where they are similar and where they differ.

The RCMP notes that the Modern Hunter shares things like the bolt release, magazine release, safety selector, and recoil buffer system. But those things aren't the deciding factor: uppers and lowers are.
Rather than using an AR-15 hinged design, the Modern Hunter upper mates to a tapered trunnion inside the lower receiver. The upper slides onto the trunnion, and a cross pin up front holds it in place. So rather than punching pins and the upper lifting free, the Modern Hunter requires you to pop the front pin, break the suction on the trunnion, and slide the upper forward and up. It takes a little getting used to, but is still ultimately a quick and easy take down process.

The sloping profile of the receivers also means that the Modern Hunter upper cannot fit onto an AR-15 lower. This saves it from the "guilt by association" fate visited on guns like the Akdal MKA1919, a gas operated shotgun that shares no AR parts, but can be forced to fit onto an AR-15 lower.

It is not some miraculous fluke that this rifle meets the non-restricted requirements. The Modern Hunter is an example of exquisite design carefully tailored to Canadian requirements, changing the way we think about black rifles and variants. For a shop like Alberta Tactical Rifle to produce an explicitly Canadian rifle is exceptionally rewarding, and highlights the dedication of our domestic firearms industry.
