The origins of the much enjoyed AR-15 platform started back in the mid-1950’s with Eugene Stoner’s 7.62mm semi-automatic rifle design, the Armalite Rifle Model 10, also known as the AR-10. In 1957, Mr. Stoner and two engineers, Jim Sullivan, and Bob Fremont, were tasked to design a scaled down version of the AR-10 to use a .22 calibre cartridge and the result was the Armalite Rifle Model 15. Due to poor marketing of the AR-15 design, Fairchild Engine and Airplane Corporation, the parent company of Armalite, sold the AR-10 & AR-15 designs to Colt’s Patent Firearms Manufacturing Company in 1959. Starting in 1962, the AR-15 design was utilized and adopted by the military of the United States in both the original and a fully automatic version, the M-16; and saw the design’s first true widespread usage during the war of Vietnam. There were many issues, which were found during those years of abuse and extreme environmental usage. You may have seen the movies and videos of soldiers of that era equipped with an AR-15/M-16 who religiously cleaned their rifles in every moment outside of actual combat. There is a bit of truth in that, hence why those scenes were so common.
Fast forward, a half a century and the AR-15 platform has become the measuring stick for determining what construes the Modern Sporting Rifle. The widespread definition of a Modern Sporting Rifle, to be called MSR henceforth, came about in 2009, as Mr. Randy Luth, then retiring President and Founder of DPMS firearms, continued to promote the AR-15 platform as a viable firearm to the hunting market in the United States. A MSR is one of which has most, if not all, of the following features:
- Semi-automatic in operation. The redirection of a portion of generated energy to enable self-reloading allows for lower recoil, and thereby faster recovery and follow-up shots.
- Mounts a pistol grip. This allows for more comfortable hold as well as having more ergonomic access to operating controls of the firearm (safety, bolt release, etc…)
- Utilizes a detachable magazine as a means of reloading the firearm both simply and easily.
- Has an adjustable stock which enable the ability to allow for personalized “fit-up” for individual users.
- Incorporates accessory mounts that allow the installation of optics as well as possibly multitude of other accessories that are customized to the individual’s requirements.
With over 50 years of history and production of a wide variety of AR styled rifle platforms, it has become such a popular design that a seemingly endless number of manufacturers offer their own versions. With prices of a few of these ranging up to several thousand dollars before even buying a magazine, the AR runs the gambit for value for the consumer’s ability and desire to purchase quality and performance. The balance point for the individual user is the issue, but stereotypically firearms owners in Canada are somewhat frugal in nature. The old saying of “Knowing is half the battle”, applies to O’Dell Engineering, a Canadian distributor of firearms and accessories has taken that to heart with their recently launched Lightweight Modern Sporting Rifle, or LMSR. It incorporates modern polymers and proven designs to bring a quality AR platform rifle to the firearms community of Canada.
Here at Tactical, Practical & Fantastical; were delighted to acquire one of the original entry level LMSR’s offered by O’Dell Engineering and have brought it to you, our readers.. So without further delay let’s take a look at the intro level LMSR available in Canada.
The LMSR is an AR-15 platform rifle, which incorporates all the features mentioned about for defining a Modern Sporting Rifle, and like a typical AR-15 has three primary components. A lower receiver, an upper receiver and the bolt carrier group. The lower receiver in this case is manufactured by American Tactical and is comprised of injection-molded polymer and is machined to exacting specifications. The standard AR15/M4, six position polymer stock is mounted on the commercial diameter buffer tube and factory trigger comes set between four to five pounds of force. The controls are the standard common versions found on most basic AR platforms.
The upper receiver is an anodized black, A3 flattop profile, that is machined from cast 7075-T6 aluminum which is roughly 50% stronger than 6061-T6 aluminum for superior wear, stress resistance and fatigue levels. The barrel of the reviewed LMSR is hammer forged and 406mm (16.0″) in length. The barrel itself has a surface treatment known as Melonite Nitrocarburizing Process, which not only adds surface hardness, but also improves corrosion and wear resistance as well. Chambered in 5.56x45mm and sporting a 1 in 7″ rate of twist, the barrel also has a protected crown, also known as a recessed crown; and a bolt-on low profile, picatinny railed gas block located at the carbine positioned gas port. The receiver rail and the gas block rail are not co-linear in height however, so prospective users should be aware of this fact.
The furniture is basic and black, with a standard A2 grip and two-piece, carbine length, hand guards. With the rear take down pin movement being extremely snug to insert and remove; the upper and lower fit together so securely that there is absolutely no need for an accu-wedge or shimming to have a solid, rattle-free, assembly.

As this specific rifle is to become the test rifle for many future accessories to be reviewed here at TPF, it was only fair for the author to put this rifle through it’s paces and season it. So over the course of the last year this rifle has had several hundred rounds fed through it, both to test accuracy and durability of what is a value priced, entry level AR platform for the Canadian marketplace. For our labour of love the author mounted an Eotech 512.A65 far forward on the upper’s picatinny rail to ensure that there was minimal possible distortion. Once dialed in, the rifle spit 45-55 grain projectiles downrange and consistently was able to shoot 20 cm (8″) diameter steel plates from offhand shooting positions @ 91m (100y) and engage all forms of targets in local 3-Gun scenarios. TPF’s LMSR in the factory configuration has been tried with a variety of magazines, several hundred factory and reloaded rounds of ammunition and has suffered zero failures to fire and eject at the time of this TPF installment.
The LSMR (Intro Level) comes with a 16″ barrel length, which has an MSRP of $899.99 CDN and is assembled and distributed throughout Canada by O’Dell Engineering Limited. To find a retailer near you access their Dealer page. There is a premium version available that is outfitted with a High Standard, chrome lined barrel in 16″, 14.5″ or 10.5″ length options; all of which have a 1/2″-28 threaded A2 flash-hider “birdcage” mounted and sport an bayonet lugged A2 gas block with a fixed front sight for true co-witness ability. The question is whether you the reader feel that the LMSR is Practical, Tactical, or Fantastical.
P.S.: The LMSR has, as of mid-2014, been upgraded with a second generation lower with added features and manufacturing advancements. The new rifle designation is the LMSR2. If you want to ask the Distributor questions you can reach them on facebook HERE.
