ArmorSource AS-501 GEN II Mid Cut Slick Ultra Lightweight Helmet



ArmorSource AS-501 GEN II Mid Cut Slick Ultra Lightweight Helmet


Proudly introducing the next generation of ballistic head protection. The ArmorSource AS-501 G2 Helmet solution is the lightest version of the U.S. Army Advanced Combat Helmet (ACH / LWACH) on the market. Designed to minimize weight burden, the AS-501 G2 has effectively reduced the weight of the traditional ACH helmet by more than 30% and that of LW-ACH helmets by more than 15%. All while exceeding the ballistic protection of the Lightweight ACH category as a whole, thanks to our proprietary materials and superior development capabilities.

The ArmorSource Difference

We protect the world’s most demanding users with proven ballistic performance. Compare the effectiveness of our products side by side.

ArmorSource Imperial Test Results

Innovative solutions designed to improve operator safety.

Within ArmorSource’s ongoing effort to improve safety, reduce helmet weight and minimize the effects of weight strain placed on military and law enforcement operators, we revolutionized the industry with the introduction of our Boltless solutions in 2012 for use with our ASR Picatinny Side Rails. To further improve these systems, our Advanced Adhesive Technology was later introduced in 2020 and is now utilized and trusted by tens-of-thousands of operators in the USA and around the globe.

ArmorSource’s Advanced Adhesive Technology is a reliable and effective alternative to traditional bolted systems, which require drilling 4 to 11 holes through the ballistic shell. Through those holes, bolts and screws are used to attach retention systems and mounts to the shell. This hardware can result in an overall reduction in ballistic performance and potential injury should the wearer be subject to a ballistic impact.

Unlike bolted systems that require constant maintenance, tightening and tools due to loss of bolts or screws, or replacement due to rust, especially in areas with high humidity, ArmorSource’s Boltless system is a tool free, permanent and reliable technology upgrade.

As modern day threats evolve, so do the solutions we provide.

The success of a Ballistic Helmet hinges on how well it can accommodate the ever-changing needs faced by
soldiers and law enforcement agents in the field.

As the threats they face continue to evolve, so too must the solutions we provide. ArmorSource is constantly pursuing solutions to trim weight, increase ballistic performance, improve comfort, deliver industry changing products and to ultimately set the standard for ballistic helmet performance.

Our products are designed, first and foremost to protect today’s war fighter and LE officer, but beyond that they are designed to serve the user in the most ergonomic way, with the highest level of compatibility for common accessories, apps and add-ons.

In today’s world a helmet is relied on for protection and as a platform for other accessories, devices and applications. ArmorSource’s universal geometry helmets are designed to work in conjunction with common devices, accessories and components that are offered and available in the market.

Ballistic performance is the foundation from which we build upon.

ArmorSource is dedicated to maximizing the survivability of military and law enforcement personnel around the globe. Thanks to our advanced ballistic solutions and state of the art manufacturing abilities ArmorSource is the driving force behind the evolution of modern-day ballistic head protection, and the direct link to a safer, more confident means of operating.

Our goal is simple – as we progress into the future, ArmorSource’s GEN II products aim to deliver improved performance with reduced weight. Below are some of the improvements we’ve made within our next Generation solutions:

Weight Reduction

With significantly lower areal density – up to 30% lighter than our legacy solutions – our Gen II shells deliver helmet solutions that are more comfortable and user friendlier than ever before. 

Improved Ballistic Performance

Pressed using ArmorSource’s unique cold and hot process, our proprietary blend of Polyethylene and Composite Materials provide a superior shell with improved bullet and fragmentation protection, even under extreme weather conditions. 

Environmental and Mechanical Performance

Though significantly thinner and lighter than the competition, ArmorSource’s GEN II Technology PE based shells deliver a more rigid product, and improved protection against threats like blunt impact, compression, Impact resistance and more, within common and extreme weather conditions.


There are two safety elements associated to the GEN II:

Reduced Weight Strain

A user that wears a helmet weighing as little as 1 Kg / 2.2 lbs will in most cases, continue to wear it for longer periods of time. There’s no denying that a lighter helmet feels more comfortable and produces less weight strain. And as we know, the longer an operator wears their helmet, the safer they are.

Improved Focus

The lighter the shell, the more focused and mission-oriented an operator will be. ArmorSource helmets are meant to be forgotten. The less time a soldier or LE Officer spends thinking about their helmet, increases the time they spend focusing on the mission at hand.

User Experience


Fit and comfort matter most. With its light weight and improved system ArmorSource helmets are designed to provide operators with the highest level of comfort and functionality on the market.


Using a Universal Shell, Rails and Shroud, ArmorSource Gen II helmets are compatible with most available helmet accessories, mounts, visors, goggles and interfaces on the market. 


ArmorSource GEN II helmets are compatible with a wide range of suspension / pad systems, and retention / chinstrap Systems, all of which are customizable per user specifications.

Helmet Sizing

Getting the right fit is important for performance and comfort. Use a tape measure and caliper to take measurements. The wearer MUST be seated in an upright position for proper fitting. 

NOTE: If any measurement falls on the dividing line between sizes, select the larger size.
