There’s been no lack of digital ink spilled over the AR-10 and AR-15 rifles. We’ve finished our justifiable share right here. However side-by-side, how do the rifles stack up towards one another and which one is best for you?


Like something firearms, all of it relies on what you intend on doing while you’re behind the set off. Given a grasp gun designer has but to put out the right all-around firearm that does completely the whole lot demanded of it, we’ve to just accept each has its skills and limitations. Hopefully, we’ll clear up precisely what these are for the preferred members of the AR household right here and work out what wins for you in terms of AR-10 vs AR-15.

Transient Historical past Of The Rifles

ArmaLite, a division of Fairchild Plane, had average success designing special-purpose firearms for the army within the Fifties. Nonetheless recognized at present, amongst their earliest achievements was the AR-5 survival rifle, adopted by the U.S. Air Pressure and meant to maintain downed airmen. In 1956, the corporate and its chief engineer — the legendary Eugene Stoner — set their sights on bigger sport — a contract for the U.S. Army’s battle rifle, changing the then outdated M1 Garand. It’s entrant to the trials was the AR-10.

Designed a yr earlier, the rifle was forward-looking sufficient to set any previous breed ordnance officer’s enamel on edge. As an alternative of metal and wooden, Stoner turned to aluminum alloy, brass and woven fiberglass for the ArmaLite Rifle (what AR stands for). There was barely a lick of cold-hard metal on the 7.62x51mm rifle, which proved its downfall. In opposition to Stoner’s recommendation, ArmaLite insisted on an aluminum-steel composite barrel — one of many first such configurations tried. Lengthy story brief, it ruptured throughout the torture-testing phase of the trials, and so did ArmaLite’s hopes at a army contract. The M14 would go on to finally win the trials, besting not solely the AR-10, but additionally the equally iconic Fabrique Nationale FAL.

Regardless of the setback, Stoner and firm knew they’d a winner on their fingers. As gun writers on the time documented, the trial’s testers have been impressed together with his creation. Some even went as far as to say it was the perfect battle rifle ever put by the paces on the Springfield Armory. ArmaLite tried to curiosity the world’s militaries within the AR-10, with restricted success. The rifle then languished for practically 30 years, till Knight Armament partnered with Stoner to resurrect the design. Reborn the Stoner Rifle 25 (SR-25), and configured for long-range operations, finally the US Particular Operations Command adopted the rifle and designated because the Mk11 Mod 0 sniper rifle. Later, it changed the U.S. Military’s M24 Sniper Rifle System with a varient designated the M110 SASS.

After the original Mk 12, the government used Knight’s Armament handguards for the Mod 1 version of the Mk 12. If that’s the one you want, then go forth and find Knight’s hardware to build yours.

As firearms historical past buffs are acquainted, it didn’t take till the flip of the century for the AR-10 design to return into its personal, nonetheless.

Reconfigured and shrunk down, ArmaLite submitted primarily a small-bore model of the rifle — the AR-15 — in 1958 for testing with the U.S. Military’s Continental Military Command. After learning World Warfare I and II engagements, CONARC had the bold purpose of changing a laundry checklist of storied army arms with a single rifle. To attain this, CONARC commander Gen. Willard Wyman requested a low-recoil 5.56 rifle, weighing 6 kilos, feeding from a 20-round journal and the power to penetrate each side of an ordinary Military helmet at 500 meters. The AR-15 to a tee.

Study Extra About The AR-10:

Initially rejected and the design offered to Colt, the rifle lastly received a champion in Basic Curtis LeMay. In 1961, as Chief of Workers of the US Air Pressure, he ordered 80,000 AR-15s, discovering army personnel might hearth the lower-recoil rifle extra precisely and that troopers tended to choose them greater than the 7.62 NATO M14. Military testing backed up these anecdotal accounts, discovering 43-percent of troopers certified as an knowledgeable with the AR-15, in contrast with 22-percent taking pictures the M14. Furthering the AR’s case, the AK-47 proved a superior weapon in contrast the M14 within the early years of Vietnam. Regardless of all this, the Military’s brass remained unconvinced concerning the small-bore rifle. The AR-15 lastly received the day in 1963, deemed the one rifle that might meet manufacturing calls for, at which the M14 was faltering.


In 1964, the army variation of the AR-15 —  M16 — went into manufacturing and was adopted. It continues to serve the U.S. army at present together with its shorter M4 Carbine variant — each choose hearth weapons. Nearly instantly after the adoption of the rifle by the army, Colt started producing the semi-automatic civilian model we all know at present because the AR-15. The identify was retained to pay homage to ArmaLite’s unique creation.

AR-10 vs AR-15 Vary

Each the AR-10 and AR-15 are available in quite a lot of chamberings, which impacts the vary issue tremendously. For the sake of simplicity, we’ll confine our dialogue to the preferred caliber for every rifle: the .223 Rem./5.56 NATO for the AR-15 and .308 Win., for the AR-10. Each are wonderful choices for AR rifles, however, usually talking, every excels at totally different ranges.

For near mid-range taking pictures, it’s tough to beat an AR-15 in 5.56. It’s an intermediate-range cartridge, designed to shine 500-yards on in. And given its mild recoil, even in a platform as lean because the AR-15, it’s a less complicated system to position a number of photographs very precisely on a goal. If it’s longer ranges you search to grasp, then the AR-10 might be going to suit the invoice. There’s a cause why the Military selected a variant of the SR-25 because the successor to the bolt-action M24 Sniper System. The bigger calibers with their heavier bullets are merely simpler to get on the right track 500-yard plus.

An instance. Say out of your AR-15, you have been taking pictures .223 Rem. American Eagle 55-grain FMJ BT and out of your AR-10 .308 American Eagle 150-grain FMJ BT, with a ten mph crosswind. The wind would defect the small-caliber spherical a full 10-inches greater than the .308 at 500 yards and greater than 50 inches at 1,000 — 179.2 inches, in comparison with 120.2. And whereas the .223 drops lower than the .30-caliber out to 600 yards, at 1,000 yards — with velocity waning — you’d should account for a further 70 inches of drop with the small-bore spherical in comparison with the .308.

As of late, the AR-15 has added extra long-range choices (mentioned extra within the calibers part) that hold tempo with AR-10 standbys. Although, as mentioned under, these are small-bore choices. They’re going to go the gap however won’t have the vitality you require for some long-range functions.

AR-10 vs AR-15 Measurement

Measured towards your entire world of rifles, the brother ARs are extraordinarily mild. Greater than merely supplies, this attribute is because of Stoner’s pioneering direct-impingement fuel operation (what Stoner referred to as an “increasing fuel system”) that depends on little greater than tubes, fuel block and fuel key to cycle the rifles. Gracefully sparse, there’s no piston so as to add further weight to both rifle.

AR-10 vs AR-15 the latter generally has the advantage of being lighter and smaller

Nonetheless, face to face, there’s usually a notable distinction within the heft between the AR-10 and AR-15. Usually, most AR-10s weight in at about 7 kilos empty and the AR-15 proper round 6 kilos. On paper, not worlds away. In an operation the place both rifle would suffice, that one much less pound has the potential to make the rifle extra manageable. The AR-15 can also be trimer in general measurement.

Definitely, 14.5-inch barreled AR-10s are round, however they aren’t as widespread because the 18- and 20-inch selection. Given that almost all shooters have distant targets in thoughts after they load up the rifle, this shouldn’t come as a shock. The additional velocity the longer bore milks from the cartridge is definitely worth the rifle being a bit extra unwieldy. Conversely, AR-15’s with 14.5-inch barrels are legion, which additionally is smart. Not solely is its intention usually medium vary in, additionally it is a popular for CQC. Opting carbine makes all of it the simpler to handle the AR-15 within the tight confines of a home or inside a constructing.

AR-10 vs AR-15 Compatibility

To not knock diehard AR-10 shooters’ collective noses misplaced, however the AR-15 has its huge brother beat in spades on this side.


Given its lengthy army service document, the rifle is rather more standardized than its huge brother. In flip, the platform is that a lot simpler to construct, improve and keep. For probably the most half, it’s a decide and place process that entails little compatibility analysis, if the AR-15 is aligned with mil-spec requirements. A latecomer to army service, the AR-10 had extra time to be tinkered with, thus skewing how the gun is put collectively. Briefly, totally different manufacturers of the rifle don’t play good with one another.

Fortunately, there’s some consistency with two patterns dominating the market — DPMS’s LR-308 and ArmaLite’s AR-10. The difficulty is, the receivers and the most important inner elements are usually not appropriate. A DPMS higher receiver is just not meant to go on an AR-10 decrease receiver. An AR-10 bolt-carrier group is just not designed to perform with an LR-308 sample barrel. Neither makes use of a barrel nut with the identical thread depend.

AR-10 vs AR-15, the larger gun has the advantage

This doesn’t imply there aren’t a mess of components and aftermarket upgrades accessible for the AR-10, LR-308 and different variations. There are many them — although, LR-308s are extra widespread and, in flip, are likely to have an availability and choice benefit. Shooters who go for the bigger AR-style rifle will need to have their analysis caps on and present further diligence when purchasing to verify they’re getting the best half for his or her rifle.

AR-10 vs AR-15 Calibers

Each rifles’ caliber decisions have swelled over time. It’s on the level now that if there’s a caliber you’ll be able to consider, there’s most definitely an AR-15 or AR-10 chambered for it.

Usually talking, AR-10-style rifles — given their bigger recievers — are likely to shoot extra bigger and extra highly effective cartridges. Initially chambered for .308 Win./7.62x51mm NATO, there are examples of 6.5 Creedmoor, .45-70 Govt., and even .300 Win. Magazine. rifles. When you’re keen to go proprietary, there’s hardly a cartridge the AR-10 can’t deal with and, most definitely, some entrepreneurial gunmaker has a rifle chamber for it.


The AR-15 is almost equally as deft in its caliber choice, with a bunch of choices pouring out previously 20 years. Nonetheless, because it was designed to fireplace the fairly demure 5.56 NATO spherical, it faces some limitations. It’s by no means going to digest the extra highly effective fodder of its huge brother.

This traditionally has meant the AR-10 was the extra logical long-range choice, however occasions have modified over time. By way of the work of Nosler with the 22 Nosler and Federal Premium with the .224 Valkyrie, the market has expanded to incorporate some ballistically proficient AR-15 rounds. Designed to offer the likes of the 6.5 Creedmoor a run for its cash, the small-bore thunder-bolts are able to putting down vary. That stated, what they convey to the desk in ballistic coefficients, they don’t make up for in vitality after they attain a distant goal in contrast with, say, a heavier AR-10-compatible spherical such because the .308 Win., or 6.5 Creedmoor.

However, close to or far and the whole lot in between, the AR-family of rifles have you ever coated.
