Brigand Arms ATLAS, AR-15 Carbon Fiber Quadrail Handguard
Brigand Arms handguards utilize a free-float barrel nut system (externally threaded alloy aluminum barrel nut and a steel jam nut). This allows fine adjustment in alignment and secure mounting.
- Tube: Patented carbon fiber braid
- Caps: Aluminum
- Barrel nut included.
- 9″ - 3.0 oz,
- 12.375″ - 5.0 oz,
- 15"- 4.0 oz
- Tube: Patented carbon fiber braid
- Caps: Aluminum
- Barrel Nut: Standard Free Float w/ Jam Nut (included)
Weights: Listed in the graphic below. The standard mil-spec barrel nut we include is an additional 2.66 oz. Other barrel nuts you can find from specialty suppliers are far lighter.
Patented Carbon Fiber Braid Overview
What does it take for an innovative idea to be forged into a product worthy of the Brigand Arms name? From raw material selection and manufacturing here in the Southeast USA to testing on the range and in the bush - every step of our journey is focused on providing high quality and unique handguard solution. Some features of the Brigand handguard you can be proud to own are the little weight, rigorous field testing, rapid heat rejection, and of course the matchless style of the braided structure. Weight Budget We know the frustration of purchasing lightweight components for your weapon, only to find that the manufacturer’s weight claims are too optimistic or that additional components will add weight not listed in the sales brochure. For complete transparency, we provide the exact weight of every element of the guards. For mounting, we use the universal free-float system comprised of an externally threaded alloy aluminum barrel nut and a steel jam nut. This combination allows fine adjustment in alignment but secure mounting. These components are the same for all Brigand Arms handguards; they weigh 2.66 oz. (Take note that many manufacturers shrewdly neglect these necessary components in their weight budget!)
We know that for some customers, light-weight AR handguards are used to balance the feel of a gun with fore-end accessories such as grips, bipods, and lights. The newest ATLAS model features a revised forward cap with four rail sections machined into the same aluminum billet as the cap for a mean, minimal look that fits most common fore-end accessories. This option adds only 2.26 ounces to the weight over a bare EDGE handguard.
Not only does the Brigand Arms handguard withstand the heat of sustained firing, but it also rejects barrel heat faster than most AR handguards. Heat leaves a rifle barrel through convection (air-flow past the barrel) and radiation (infrared ‘glow’). Brigand’s open-architecture braid provides minimal resistance to air-flow, allowing heat to be blown off quickly, and offers excellent exposure to the open sky for radiated heat to escape. Does this exposure mean your hand will get hot? The open-architecture guard will warm up to operating temperature faster: However, under sustained fire, the barrel will be cooler, and the handguard will cool more quickly after firing than with any enclosed guard. This improves barrel life and decreases heat signature duration.
Materials & Design
The Brigand Arms Carbon Fiber Handguard concept is built on a platform of aerospace-proven materials and innovative mechanical design. A significant component of this is the braided carbon tube; technically called ‘Open-Architecture Composite Structure’ or O-ACS for short. The O-ACS geometry is designed in the computer using proprietary software. It is braided from individual composite yarns in a lattice that minimizes weight and maximizes stiffness and strength. Every thread within the tube is formed from T700 carbon for strength and rigidity, shrouded within a protective jacket for all-weather durability and abrasion resistance. This jacket prevents cracking (common in filament wound handguards) and splinters (common in roll-wrapped handguards). Solid metal end-caps provide rock-solid mounting on the receiver and protection from the impact on the fore end.
All metal components are 6061 aluminum, hard anodized to provide a sturdy and durable finish.
Reliability & Strength
We understand that lightweight weapons cannot sacrifice any performance for weight-savings. After engineering to the limit of performance, physical testing is a vital part of validating our designs. How sturdy is the carbon fiber handguard? We can hang 40-pound dumbbells from the end of it and swing them around with no signs of bending. Under controlled laboratory tests, the handguards can support a force of 100 pounds in any direction, and 400 pounds along with their length – more than even extreme users require. We field test every handguard configuration, firing thousands of rounds in tortuous conditions, then bring them back to the lab and inspect there are no flaws nor slowly developing cracks. Dozens of iterations have led to the current braid that we use. The resulting high-strength design is unique enough that a US patent covers it! Of course, we know it’s not fair to expect you only trust our testing: Give a Brigand handguard a try - we guarantee every handguard against manufacturing flaws and reasonable failure in the field.
