Designed for the Fastest, Easiest Install Possible
The Ragna is “different than any forend ODIN Works has ever made” – and that starts with how it mounts. Odin Works+2Tactical Ordnance+2
One-piece barrel nut design – No shims, no timing, no clocking required.
Simplified install compared to traditional multi-piece systems.
Perfect for builders who want a clean, repeatable setup without fighting alignment issues.
Whether you’re doing your first AR build or your fifteenth, the Ragna’s mounting system helps you get from bench to range faster.
Free-Floating for Enhanced Accuracy
This 17.5" Ragna M-LOK forend is a true free-float handguard: Odin Works+1
The handguard attaches to the barrel nut, not the barrel, which helps prevent external pressure from affecting barrel harmonics.
Free-floating can improve consistency and potential accuracy, especially when shooting off barricades, bipods, or slings.
Ideal for precision-oriented ARs, competition rifles, and long-range configurations.
Paired with a good barrel and trigger, the Ragna is a serious asset for accuracy-focused builds.
17.5" Length – Maximum Sight Radius & Accessory Real Estate
At 17.5 inches, this is the longest Ragna option and is perfect for full-length builds: Odin Works+2High Angle Gun Works+2
Extends close to the muzzle on most 18–20" barrels, maximizing sight radius for iron sights and giving you more support-hand reach.
Plenty of M-LOK real estate for lights, bipods, grips, and other accessories without clutter.
Great for SPR (Special Purpose Rifle) / DMR-style builds, 3-Gun rifles, or any AR where control and stability are a priority.
If you prefer a long, stable support-hand position and lots of rail space, 17.5" is the way to go.
Lightweight 6061-T6 Aluminum Construction
The Ragna forend is cut from 6061-T6 aluminum, giving it a great strength-to-weight ratio: Odin Works+2OpticsPlanet+2
Forend weight: ~8.8 oz (unassembled)
Hardware weight: ~2.65 oz Odin Works
Strong enough for hard use, yet light enough to keep your rifle nimble and well-balanced.
Deep machining cuts and windows help shave weight while giving the handguard a distinctive, modern look.
M-LOK Attachment Where You Need It
The Ragna M-LOK Forend uses the industry-standard M-LOK interface: Odin Works+2Tactical Ordnance+2
M-LOK slots positioned at 3, 6, and 9 o’clock for flexible accessory placement. Odin Works
Compatible with a huge ecosystem of M-LOK accessories: bipods, grips, handstops, flashlight mounts, sling QD cups, and more.
Top remains mostly open for a monolithic upper look when combined with your receiver’s Picatinny rail.
This gives you exactly what you need for a modern fighting, competition, or hunting rifle—without unnecessary bulk.
Optimized Internal Dimensions & Gas Block Compatibility
ODIN Works designed the Ragna to work smoothly with typical low-profile gas blocks: Odin Works+1
Inside diameter: approximately 1.35" Odin Works
Outside dimension: roughly 2.02" tall by 1.52" wide for a slim but rigid profile. Odin Works
Compatible with .750 ODIN Works gas blocks (non-clamp-on) that fit inside the forend. Odin Works
This tight-but-functional profile keeps the rail compact in the hand while still providing the clearance needed for most setups.
Tough Type II Hard Anodize Finish
The Ragna handguard is finished with Type II hard anodizing: Pelcher Outdoors+1
Provides increased wear and corrosion resistance.
Gives the forend a matte black finish that pairs well with most upper receivers and barrels.
Ready for hard field use, training classes, and competition environments.
It’s built to look good and stay that way through serious use.
All Mounting Hardware Included
Everything you need for installation comes in the box: Odin Works+1
One-piece barrel nut with black nitride coating. Odin Works
