The LBX Tactical Armatus II is a low-profile plate carrier built around a Shooters Cut SAPI plate pocket and a 3/4-inch fast-clip front panel system. The carrier ships with two included panels — the LBX-4020B Triple M4 front panel and the LBX-4040A removable back modular panel — and accepts the full range of 3/4-inch MAP-compatible components on the back. Available in Medium and Large sizing, with plate compatibility spanning Small through Large SAPI single-curve plates depending on the carrier size selected.

Who this is for

• Patrol officers and security professionals who need a low-profile carrier that disappears under a outer garment or integrates cleanly into a duty uniform without sacrificing MOLLE capacity.
• Competitive shooters and trainers who run drills regularly and want a carrier with removable shoulder straps and a modular cummerbund they can configure for comfort across long range days.
• Preparedness-minded civilians who want a purpose-built SAPI-cut carrier with a reinforced drag handle and integrated admin pocket ready to run without additional modifications.

Plate compatibility

The Armatus II plate pocket follows the Shooters Cut SAPI geometry. Plates must be single-curve. The front panel uses a 3/4-inch fast-clip attachment system, and both front and back panels are removable. The included LBX-4020B Triple M4 front panel attaches via this clip system; any 3/4-inch MAP-compatible panel swaps in without tools.

Plate fit depends on the carrier size ordered:

Plates thicker than 1 inch are not compatible with this carrier. Multi-curve and triple-curve plates will not seat correctly in the single-curve SAPI pocket. Confirm your plate's cut and thickness before ordering.

MOLLE coverage and capacity

The included LBX-4020B Triple M4 front panel provides dedicated rifle magazine real estate on the front face of the carrier. The LBX-4040A back panel is modular and accepts 3/4-inch MAP components, extending the carrier's organizational capacity to the rear without permanent modifications. Loop ID fields appear front (3 inches x 5.75 inches) and rear (9.5 inches x 3 inches), allowing hook-backed patches, name tapes, and unit identifiers to mount without hardware.

Sizing and adjustability

The Armatus II ships in two sizes — Medium and Large — each sized to the SAPI plate geometry described in the plate compatibility table above. The cummerbund is a removable, adjustable modular mesh design with a rib cage profile, allowing independent adjustment of lateral tension without tools. Shoulder straps are padded and removable, so the carrier can run stripped for warm-weather or high-movement use cases. A reinforced drag handle sits at the top of the carrier for emergency extraction.

Comfort and construction

The shell is 500D Cordura throughout. A front zipper admin pocket measuring 4.5 inches x 5.75 inches sits on the front panel and provides fast-access document or small-item storage. The mesh cummerbund reduces heat retention at the torso compared to a solid foam-backed panel, and the padded shoulder straps distribute vertical load across the shoulder contact area. The modular back panel system means the rear of the carrier can be stripped to a flat profile or loaded with MAP accessories depending on mission requirements.

Specifications

Fit and carrier compatibility

The Armatus II is sized by SAPI plate geometry, not by chest circumference. Select the carrier size that matches your plate size: Medium carries Small or Medium SAPI plates; Large carries Medium or Large SAPI plates. The recommended plate for each size is the larger of the two options listed, run at 3/4-inch thickness. If your plates exceed 1 inch in thickness or use a multi-curve profile, contact us before ordering to confirm compatibility.

Frequently asked questions

What plate sizes fit in the Armatus II?

The Medium carrier accepts Small SAPI (8.75" x 11.75") or Medium SAPI (9.5" x 12.5") plates. The Large carrier accepts Medium SAPI (9.5" x 12.5") or Large SAPI (10.125" x 13.25") plates. All plates must be single-curve SAPI cut. Medium SAPI is the recommended plate for the Medium carrier; Large SAPI is recommended for the Large carrier.

Does this carrier come with plates?

No. The Armatus II ships with the LBX-4020B Triple M4 front panel and the LBX-4040A removable back modular panel, but no ballistic plates are included. Plates must be purchased separately. Browse our hard armor plate selection to find a single-curve SAPI-cut plate in the correct size for your carrier.

Will my 10x12 Shooters Cut plates fit?

A 10x12 Shooters Cut plate does not match the SAPI geometry this carrier is designed around. The Armatus II plate pocket follows SAPI dimensions — not the common commercial 10x12 Shooters Cut format. A Medium SAPI plate (9.5" x 12.5") is the closest match for the Medium carrier. Contact us if you are unsure whether your specific plate will seat correctly.

Can I remove the cummerbund and shoulder straps?

Yes. Both the modular mesh cummerbund and the padded shoulder straps are removable. Running the carrier stripped reduces bulk and weight, which can be useful in high-heat environments or for vehicle-mounted use where the cummerbund creates interference.

How does the 3/4-inch MAP panel system work?

The front and back panels attach via a 3/4-inch fast-clip system. Any LBX MAP-compatible accessory panel with a 3/4-inch clip interface swaps directly onto the carrier without tools. The included Triple M4 front panel and modular back panel both use this interface, and the system is designed for rapid panel swaps in the field.

Is there a quick-release system on this carrier?

The vendor page does not list a quick-release mechanism on the Armatus II. The cummerbund is adjustable and removable, but no dedicated emergency quick-release pull system is specified. Contact us if a quick-release-equipped carrier is a hard requirement for your application.
