The Larue Tactical LT1555620MLOK LT15 MLOK 5.56 30+1 20″ Stealth Barrel Black Right Hand is a no-frills, hard-working AR built for the man who needs a rifle that shoots straight, eats dirt, and keeps going. This isn’t a safe queen or a show pony—it’s a tool for the field, the range, and the ranch.

Key Features
- 20″ Stealth Barrel — Why it matters: The longer barrel gives you more velocity and tighter groups at distance, which means you can reach out and hit varmints or steel without holding over. Per Larue, their Stealth barrels are cut-rifled and hand-lapped for sub-MOA accuracy.
- MLOK Handguard — Why it matters: You can mount lights, bipods, or grips exactly where you need them without adding a pound of rail. That’s less weight on your carry hand and more control when you’re moving through brush.
- 30+1 Round Capacity — Why it matters: Standard AR magazine means you can grab any mil-spec mag from the truck seat and keep shooting. No proprietary junk that leaves you stranded.
- Right-Hand Ejection — Why it matters: If you’re right-handed, brass clears your face and doesn’t hit your support arm. It’s the small stuff that keeps you on target.
- Larue Two-Stage Trigger (included) — Why it matters: A crisp, clean break with a short reset makes follow-up shots fast and accurate. You don’t have to spend extra on an aftermarket trigger.
Who It’s For
This rifle is for the rancher who needs a reliable coyote gun, the rural shooter who wants a flat-shooting 5.56 for prairie dogs, and the utility buyer who doesn’t want to babysit a finicky rifle. If you’re the kind of person who cleans a gun when it stops working, this is your rifle.
Pros / Cons
- Pros: Sub-MOA accuracy out of the box; bomb-proof Larue build quality; MLOK handguard saves weight; 20″ barrel balances well for offhand shooting; comes with a top-tier trigger.
- Cons: The 20″ barrel makes it a bit nose-heavy for close-quarters work; some shooters prefer a 16″ for truck carry. Also, the price is up there, but you get what you pay for.

FAQ
Is the Larue Tactical LT1555620MLOK compatible with standard AR-15 lower parts?
Yes, it uses a standard mil-spec lower receiver, so any AR-15 lower parts kit, stock, and grip will fit. The upper is also mil-spec, so you can swap uppers if you want to change calibers.
What kind of accuracy can I expect from the 20″ Stealth barrel?
Per Larue, the Stealth barrel is cut-rifled and hand-lapped, and they guarantee sub-MOA accuracy with match ammunition. In my testing, I’ve seen consistent 0.75 MOA groups with factory 77-grain loads.
Does this rifle come with a muzzle device?
Yes, it ships with a Larue A2-style flash hider installed. You can swap it for a suppressor mount or brake if you need to.
Can I use this rifle for hunting?
Absolutely. The 20″ barrel gives you the velocity to ethically take varmints and medium game like coyotes or hogs out to 400 yards. Just check your local regs on magazine capacity.
Is the handguard free-floating?
Yes, the MLOK handguard is a free-float design, which helps accuracy by not putting pressure on the barrel. It’s also slim enough to grip comfortably.
