Sierra Plate Carrier Black Front Angle + Lightweight Level 4 Plate Model 1165 front
Price for both: $379.98



The 0331 Tactical Sierra Plate Carrier is an all-terrain, all-day solution to heavy armor systems with unnecessary additions and ultra lightweight carriers without enough modularity or comfort.

Legacy systems designed for comfort lacked tactical necessities. Conversely, systems designed for tactical necessities lacked comfort. Despite existing systems, the Sierra Plate Carrier combines the best of all worlds with a modular, scalable armor platform that combines ease of use, comfort, and technical capability into a single innovative platform.

The Sierra Plate Carrier utilizes a hybrid front and back panel attachment system. Rather than forcing you to choose one system or another, the Sierra combines modern laser-cut MOLLE capability with micro loop attachment for pouches, placards, and ID panels.

But the Sierra doesn’t lack in organization, either. Durable stretch keepers on the rim of the front plate bag ensures comms, power, and hydration cables and tubes stay tight and out of the way. Not running comms or hydration tubes? Use them for chem lights, environmental camouflage, Pez, or don’t use them at all. These stretchy keepers lay flat when not in use.


Everyone likes quick-detach buckles for rapidly donning and doffing their plate carrier. But for some reason, manufacturers keep unnecessarily putting them directly in your shoulder pocket.

No more. 0331 Tactical placed them higher up on the shoulder, where they’re still accessible from either hand but completely out of the way of your tasks.

And with our hybrid expansion system, you’ll minimize adapters, webbing, and all the extra bulk and weight you’ve been forced to deal with.


The quick-detach cummerbund provides dual-face MOLLE compatibility for mounting side plates, radios, and other gear on both the interior and exterior faces. Utilize popular third-party accessories such as chest rigs, pouches, and back packs and panels with ease.

Since everyone is different, 0331 Tactical built the Sierra to accommodate virtually any armor plates you or your agency prefer. The Sierra Plate Carrier is available in Medium/Large with dual plate pockets for 10X12, Medium, and Large SAPI plates. Plus, the Large/Extra Large size also has dual plate pockets that can fit 10X12, Medium, Large, and 11X14 size plates.  Choose L/XL sizing if you’re in need of an 11×14 plate carrier.

The Sierra Plate Carrier is compatible with RMA’s IIIA, SRT, III, III+, and IV armor plates. We specifically recommend RMA’s Lightweight Level 4 Plate that weighs 6.8lbs and boasts a thin profile as a great companion to the Sierra.

  1. Tyler Bussell (verified owner)

    Well.made, seems rugged enough to endure rigorous field use and harsh conditions. Have not put it to use in said conditions as yet. But, so far, it has performed to my expectations.

  2. Christopher (verified owner)

    Very comfortable with the 1155mc plates. Have worn this rig all day long at the range for training and it’s much better than what I was running prior. Quick to get on and off as well. Glad I purchased this!
