Meet the modern do-all rifle that punches above its weight. The Alexander Arms Tactical 6.5 Grendel (RTA65DE) marries the smooth shooting manners of the AR platform with the reach and efficiency of 6.5 Grendel—a cartridge engineered for flat trajectories, high retained energy, and excellent wind performance. Anchored by a 16" black threaded barrel for easy suppressor or muzzle-device installation, this carbine wears a durable Flat Dark Earth (FDE) Cerakote on its aluminum receiver with integral Picatinny top rail. A lightweight M-LOK free-float handguard keeps accessories tight and the barrel free for accuracy, while a B5 Bravo stock and classic A2 pistol grip deliver proven ergonomics from bench to backcountry.
Whether you’re building a compact hunting rig, a practical range rifle, or a suppressed general-purpose setup, the Alexander Arms Tactical 6.5 Grendel delivers the range, consistency, and configuration flexibility serious shooters demand.
Why Choose 6.5 Grendel in a 16" Tactical Carbine
Long-Range, Low-Recoil Balance
The 6.5 Grendel’s efficient case and sleek bullet profiles provide superior downrange energy and flatter trajectories than typical .223/5.56 loads—without harsh recoil.
Real-World Accuracy
The free-float M-LOK handguard isolates the barrel from sling or grip pressure, helping maintain point-of-impact consistency across shooting positions.
Suppressor-Ready
A black threaded muzzle (standard 5/8x24*) lets you mount brakes, comps, or a suppressor for recoil control and signature reduction.
*Verify thread spec with your dealer package.
Weather-Resistant Durability
FDE Cerakote on the aluminum receiver provides a tough, corrosion-resistant finish that shrugs off field abuse and harsh weather.
Tuned Ergonomics
The B5 Bravo stock offers a stable cheek weld and multiple sling points, while the A2 grip delivers a familiar, no-nonsense interface.

Performance Benefits You’ll Notice
Extended Effective Range
Compared to 5.56 carbines, 6.5 Grendel maintains velocity and energy at intermediate distances, making it ideal for coyotes, hogs, and deer-size game (where legal) and for ringing steel past 500 yards with quality ammo and fundamentals.
Less Wind Drift, More Hits
High-BC bullets commonly used in 6.5 Grendel reduce wind drift for higher first-round hit probability in variable conditions.
Soft Shooting, Fast Follow-Ups
Threaded muzzle plus AR gas system equals manageable recoil and quick sight recovery, especially when paired with a brake or can.
Cold-Bore to Hot-String Consistency
The free-float M-LOK handguard keeps sling tension off the barrel, supporting repeatable groups through dynamic courses or prone strings.
Ideal Use Cases
Predator & Varmint Hunting: Flat shooting for coyotes and fox—carry light, shoot far.
Hog & Medium Game (where legal): Heavier 6.5 projectiles deliver deep penetration and energy on target.
Practical Carbine & Training: Low recoil with better wind performance for intermediate-range coursework.
Suppressed GP Rifle: Threaded muzzle simplifies setup; tune buffer/gas for optimal suppressed reliability.
Setup & Upgrade Ideas
Optics: A 1-8× LPVO or 2-10× gives PID up close with precision at distance; red dot + magnifier for a lighter rig.
Muzzle Device: Install a 5/8x24 brake, compensator, or direct-thread suppressor (confirm included device and thread pitch).
Accessories: Add white light, bipod, Arca/handstop, or QD sling mounts via M-LOK.
Trigger: A quality single- or two-stage trigger can further unlock the Grendel’s accuracy potential.
Ammo Tips for Best Results
Target/Steel: 107–123gr match (e.g., ELD-M, OTM) for tight groups and wind performance.
Hunting: Bonded or controlled-expansion 6.5 bullets in ~120–129gr class for ethical energy and terminal effect.
Zeroing: Many shooters prefer a 100-yard zero for predictable holds; confirm your dope with your chosen load.
Care & Maintenance
Bore & Chamber: Use copper and carbon solvents as needed; follow with a light oil.
Gas & BCG: Keep contact surfaces lightly lubricated; inspect extractor/ejector springs at service intervals.
Handguard/Receiver Screws: Verify torque after long range days; thread locker as manufacturer recommends.
Cerakote Care: Wipe with a soft cloth; avoid harsh abrasives to preserve finish.
