The ArmaLite AR10TAC18 AR-10 .308 Win 18-inch 25+1 is a semi-automatic rifle built for ranchers and rural workers who need a tool that puts meat on the table and keeps varmints off the feed lot. Chambered in .308/7.62 NATO, this platform pairs an 18-inch Cerakote stainless steel barrel with a rifle-length gas system and an adjustable gas block for reliable cycling with or without a suppressor. It ships with Magpul MBUS flip-up sights, a 15-inch KeyMod handguard, and a Magpul STR collapsible stock. Forged 7075-T6 aluminum receivers and an ambidextrous safety make it a no-nonsense workhorse for precision utility use.

Key Features
- 18-inch Stainless Steel Barrel with Cerakote Finish — WHY IT MATTERS: The 18-inch length balances handiness with velocity retention for .308 rounds, while the Cerakote finish resists rust and corrosion from sweat, rain, or mud. You don’t have to baby it.
- Rifle-Length Gas System with Adjustable Gas Block — WHY IT MATTERS: Reduces felt recoil and extends part life. The adjustable block lets you tune the gas for different loads or a suppressor, so it runs dirty or clean without choking up.
- Magpul STR Collapsible Stock and MBUS Flip-Up Sights — WHY IT MATTERS: The STR stock gives a solid cheek weld and storage for batteries or spare parts. The MBUS sights are rugged and low-profile, ready to deploy when your optic goes down.
- 15-Inch KeyMod Handguard — WHY IT MATTERS: Free-floats the barrel for accuracy and gives plenty of real estate for lights, lasers, or bipods. KeyMod is lighter than M-LOK and proven in the field.
- Ambidextrous Safety Selector — WHY IT MATTERS: Quick manipulation with either hand matters when you’re shooting from a vehicle, a fence line, or a awkward position. No fumbling.
Who It’s For
This rifle is for the rancher who needs a .308 that can reach out to 500 yards on coyotes, hogs, or steel targets. It’s for the rural worker who wants a duty-grade AR-10 that won’t quit after a season of hard use. If you run cattle, maintain fences, or patrol property lines, the AR10TAC18 is a tool you can count on.
Pros and Cons
- Pros: Accurate stainless barrel, adjustable gas block for suppressed shooting, durable 7075-T6 receivers, ambidextrous controls, Magpul furniture out of the box.
- Cons: The KeyMod handguard is less common than M-LOK today, so mounting accessories may require adapter plates. Also, the 25+1 magazine capacity is high-capacity; some states restrict it.

FAQ
What magazines does the ArmaLite AR10TAC18 use?
It accepts standard .308 Win / 7.62 NATO AR-10 pattern magazines. The included 25-round mag is a high-capacity magazine; check your local laws.
Is the adjustable gas block easy to tune?
Yes. Use a hex key to adjust the set screw. Start with the gas block fully open, then close it in small increments until the bolt locks back on an empty magazine with your chosen load. Per ArmaLite specs, the block is designed for tool-free adjustment with a standard Allen wrench.
Can this rifle shoot 7.62 NATO ammunition?
Yes. The chamber is cut for .308 Win, but it safely fires 7.62 NATO surplus and commercial loads. Always verify headspace with a gauge if switching between brands.
Does it come with a carry case?
No, the AR10TAC18 ships in a cardboard box. We recommend a soft case or hard case for transport and storage.
Is the barrel threaded for a suppressor?
Yes. The 18-inch barrel is threaded 5/8×24 TPI, standard for .308 muzzle devices and suppressors. The adjustable gas block helps manage increased back pressure.
