Best 6mm ARC Rifles for Hunting and Long-Range Use
The best 6mm ARC rifle for most buyers is the CMMG Resolute Mk4 at $1,447.32, a 6.4-pound AR-15 with a 16.1-inch stainless barrel, the cartridge-standard 1:7.5 twist, and a threaded muzzle. The Ruger American Gen II Predator at $609.99 is the value bolt-action with a 22-inch barrel, and the Wilson Combat Tactical Hunter at $2,179.03 is the premium AR-15 with an 18-inch fluted match-grade barrel. Nine factory rifles are ranked below: three AR-15s, one folding piston rifle, and five bolt-actions, each with the magazine it actually takes.

How We Ranked the Best 6mm ARC Rifles
We ranked these rifles on the specs that decide a 6mm ARC purchase: barrel length and twist, carry weight, the magazine system, and what each rifle includes for the money. 6mm ARC exists to launch high-ballistic-coefficient 6mm bullets from a small-frame action, so a rifle that gives up the fast twist or chokes the cartridge with a short barrel wastes the reason to buy it. For 6mm ARC's search-interest history against 6.5 Grendel, read the AR-15 cartridge trends breakdown.
- Barrel and twist: 1:7.5 is the cartridge-standard twist for the heavy 6mm match bullets. The CMMG and Wilson rifles use it; the Ruger runs a 1:7.7 right-hand twist on a longer 22-inch barrel.
- Carry weight: a hunting rifle gets carried more than it gets shot. The CMMG weighs about 6.4 pounds, the Wilson 6 pounds 14 ounces empty, and the Savage 110 Core Tactical 8.26 pounds before an optic.
- Magazine system: 6mm ARC rifles do not share one magazine, and the maker's magazine specification decides how easy spares are to buy.
- What is in the box: a threaded muzzle, a two-stage trigger, a precision stock, or an included scope changes what you spend after the rifle arrives.
Best Factory 6mm ARC Rifles (Ranked)
The CMMG Resolute Mk4 ranks first, the Ruger American Gen II Predator is the value bolt-action, and the Wilson Combat Tactical Hunter is the premium AR-15. The Savage 110 Core Tactical is the precision-oriented bolt gun, the Stag 15 Covenant is the fixed-stock AR-15, and the Q Mini Fix is the compact folding bolt-action. The Robinson Armament XCR-L is the folding piston rifle, the Savage 110 Ultralite Predator is the lightweight precision-stock bolt gun, and the Howa Mini Action Full Dip Yote GamePro includes a scope for hunting season.
Q also builds the Mini Fix with a shorter barrel; the 12-inch Mini Fix 6mm ARC breakdown covers how that configuration differs from the 16-inch rifle ranked here.

6mm ARC AR-15 or Bolt-Action: Which Should You Buy?
Buy a 6mm ARC AR-15 when you want fast follow-up shots and a light carbine; buy a bolt-action when you want a longer barrel, a precision stock, a folding layout, or a scoped package ready for the field. The CMMG Resolute is the lightest rifle here with a published weight, about 6.4 pounds on a 16.1-inch barrel, and the Wilson Tactical Hunter weighs 6 pounds 14 ounces on an 18-inch barrel. A semi-auto fires a second shot on a running coyote or a second hog without the shooter breaking position to cycle a bolt, which is why a 6mm ARC AR-15 ranks among the best coyote hunting rifles and the lightweight pick in the hog hunting rifle rankings.
The bolt-actions each solve a different problem. The Ruger American Gen II Predator gives you the longest barrel in the ranking at 22 inches. The Savage 110 Core Tactical and 110 Ultralite Predator add AICS magazines and AccuFit V2 stocks with ARCA and M-LOK for bipods and tripods, with the Core Tactical on a 20 MOA rail and the Ultralite Predator at 7.3 pounds. The Q Mini Fix folds for packing, and the Howa Mini Action Full Dip package includes a Nikko Stirling 4-16x44 scope, so it needs no separate optic purchase. The Robinson XCR-L splits the difference: a semi-auto with a long-stroke piston, a quick-change barrel, and a folding stock.
Already own an AR-15 lower? A 6mm ARC upper is the other path to the cartridge. The upper needs a bolt with the 6.5 Grendel-family bolt face matched to its barrel, and it feeds from 6.5 Grendel-family magazines rather than your 5.56 magazines. Price that route in the rifle builder against the complete rifles above before you order parts.
What Barrel Length Should You Choose for a 6mm ARC Rifle?
Choose 16 to 18 inches for a 6mm ARC AR-15; the longer 18- to 22-inch barrels add velocity at the cost of length. A 16-inch barrel runs roughly 2,650 fps with 105- to 108-grain match bullets and an 18-inch barrel roughly 2,720 fps, so the extra two inches buy about 70 fps. The often-quoted 2,750 fps figure comes from a 20- to 24-inch test barrel, not a 16-inch carbine.
- 16-inch barrel
- 2,650fps105-108 gr match, approx.
- 18-inch barrel
- 2,720fps105-108 gr match, approx.
- Standard twist
- 1:7.5Cartridge standard
The ranked rifles fall into four lengths. The CMMG Resolute (16.1 inches), Stag 15 Covenant, Q Mini Fix, and the Robinson XCR-L configuration ranked here run 16 inches. The Wilson Tactical Hunter and both Savage 110s run 18 inches, and Robinson also offers an 18.6-inch XCR-L barrel. The Howa Mini Action runs a 20-inch heavy barrel, and the Ruger American Gen II Predator runs 22 inches. The 20- and 22-inch bolt-actions trade handling length for velocity; on a carbine carried through timber, the 16-inch rifles are the better fit.
Gas length on the AR-15s is a per-barrel spec, not a cartridge rule: the CMMG Resolute uses rifle-length gas on its 16.1-inch barrel, while the Wilson Tactical Hunter uses intermediate-length gas on its 18-inch barrel.
What Magazines Do 6mm ARC Rifles Use?
There is no single 6mm ARC magazine. The CMMG, Wilson, and Robinson rifles take 6.5 Grendel-family AR-15 magazines, both Savage 110s take 10-round AICS magazines, and the Stag, Q, Ruger, and Howa rifles take the magazines listed for each below. Buy spares only after the rifle is chosen, and buy two or three at once so a lost or damaged magazine does not end a hunt.
- CMMG Resolute Mk4: ships with CMMG's 10-round magazine, which CMMG labels for 6.5 Grendel, 6mm ARC, and 22 ARC.
- Wilson Combat Tactical Hunter: Wilson specifies 6.5 Grendel magazines for its 6mm ARC rifles. The ASC stainless 10- and 25-round AR-15 6.5 Grendel magazines below belong to that family.
- Robinson Armament XCR-L: Robinson specifies 6.5 Grendel DuraMags made by CProducts Defense, such as the DURAMAG SS 26-round.
- Q Mini Fix: Q's manual assigns AR-15-pattern magazines to the Mini Fix.
- Ruger American Gen II Predator: ships with a 10-round AR-style magazine.
- Savage 110 Core Tactical and 110 Ultralite Predator: both use 10-round AICS magazines. Match spares to the 6mm ARC chambering rather than assuming any AICS magazine will feed it.
- Stag 15 Covenant: ships with a 10-round black aluminum magazine with an anti-tilt follower.
- Howa Mini Action Full Dip: ships with a five-round magazine.
The CMMG Resolute and Wilson Tactical Hunter take these 6.5 Grendel-family magazines, and the DURAMAG SS 26-round is the model Robinson specifies for the XCR-L.

The Verdict
Buy the CMMG Resolute Mk4 ($1,447.32) as your first 6mm ARC rifle. Pick the Ruger American Gen II Predator ($609.99) for a bolt-action, or the Wilson Combat Tactical Hunter ($2,179.03) for the premium AR-15.
The CMMG gets the cartridge right where it matters: a 1:7.5 twist, a threaded 16.1-inch barrel, and a 6.4-pound weight you can carry all day. Choose the Savage 110 Core Tactical for a precision stock and AICS magazines, the Q Mini Fix or Robinson XCR-L for a folding rifle, and the Howa Mini Action Full Dip package when you want the scope included. Whichever rifle you buy, order its magazines by the maker's specification, not by the cartridge name.
