A chest rig is a harness that carries magazines and gear on the front of the torso without any armor. For police, it makes sense when an officer needs ammunition and equipment close at hand but is not wearing a plate carrier, or is wearing armor under a uniform. If armor is required for the assignment, a chest rig does not replace it. That distinction sounds obvious, but it is the most common point of confusion we hear from buyers. Here is how chest rigs fit into an agency’s gear plan and what to check before you order. For law enforcement professionals: your agency’s training officers and SOPs should guide your specific setup and employment. This article focuses on gear specifications and considerations to inform purchasing decisions. What a tactical chest rig actually is A tactical chest rig has two parts. The harness goes over the shoulders and around the back. The front panel, usually called a placard, holds magazines or pouches. Older chest rigs were one sewn unit. Most current designs, including HRT’s, separate the two. The harness is sold on its own, and the placard clips onto it with buckles. That modular approach is the reason chest rigs have become relevant to agencies again. How HRT’s chest rig setup works HRT builds its chest rig around the H Harness. HRT lists these features: Sold as harness only, placards not included 500 denier Cordura construction Integrated Duraflex buckle system that attaches to Gen II HRT placards with side loops Works with most placards on the market Webbing and Velcro on the straps for push-to-talk units, cables and hydration tubes Velcro loop panel on the back for ID or patches Lifetime warranty The practical point for buyers is that the same HRT placard can move between an HRT plate carrier and the H Harness. One placard, two ways to carry it. If your agency already issues HRT carriers, adding harnesses can be a low-cost way to give officers a no-armor option without buying a second set of pouches. One compatibility detail to confirm: the placard needs side loops to connect to the harness. Older HRT placards without them will not attach directly. Micro chest rigs vs full-size rigs A micro chest rig is a smaller placard on the same harness. It typically holds a few rifle magazines and little else, keeping the profile flat and light. HRT’s Modulus Placard is an example. HRT lists it as holding three AR15-style magazines, measuring 9.25 x 6 inches, with height-adjustable straps and compatibility with most chest harnesses. HRT’s newer Modulus 2.0 uses a laser-cut design and accepts most HRT placard inserts. Full-size rigs use larger placards or MOLLE placards that carry radios, medical gear and admin pouches alongside magazines. The trade-off is simple: more storage, more bulk. When a chest rig fits the assignment Which setup suits a given role is a decision for each agency’s own policy and training staff. This post covers published specifications only. From a purchasing view, these are the situations where agencies commonly evaluate chest rigs: Officers wearing concealable soft armor under the uniform who still need rifle magazines accessible when deploying a patrol rifle Units that already issue plate carriers and want a lighter, no-plate option for assignments where armor is not part of the requirement Training and range use, where a harness with the duty placard keeps the same magazine layout without the weight of plates Roles with long wear time where a lighter load-carrying option is a priority And where a chest rig is the wrong buy: When the assignment calls for rifle-rated protection. A chest rig carries gear, not plates When the officer needs a single, permanent kit. A plate carrier with a placard already covers the gear-carrying role Chest rig vs belt-mounted gear The other option many agencies weigh is putting magazines and pouches on a belt. HRT’s first line belts and pouches are built for that. A belt keeps the chest clear and moves weight to the hips. A chest rig keeps gear higher on the torso and frees up the belt. Many agencies issue both, with the belt as the everyday base and the chest rig added when the assignment calls for more magazines. That split is a policy choice, not a gear rule. What to check before ordering chest rigs Confirm placard compatibility. HRT’s H Harness connects to Gen II placards with side loops Decide on placard size up front: micro for a light magazine load, full-size or MOLLE for radios and medical gear Check whether officers already have HRT placards on their carriers, since those can transfer Count harnesses and placards separately.

The HighCom Guardian 4s17M is a Level IV stand-alone, multi curve rifle plate built with a ceramic strike face and composite backing. It is certified to NIJ Standard 0101.06, listed on the NIJ Compliant Products List, and compliant with the DEA Hard Armor Protocol. The 10×12 shooters cut weighs 7.2 lb (3.3 kg) and is 0.95 inches thick. That combination of armor-piercing protection at a mid-range weight is why the 4s17M shows up so often on agency equipment lists. Here is what the spec sheet actually says, and what to weigh before you issue it. What “Level IV stand-alone” means on this plate Stand-alone means the plate does not need soft armor behind it to meet its rating. Under NIJ 0101.06, Level IV is the highest rifle rating, and the test threat is a .30 caliber M2 armor-piercing round. HighCom’s spec sheet lists the 4s17M as tested against that round at 2,880 ft/s. If you are reading newer spec sheets, you will see NIJ 0101.07 terms like RF1, RF2 and RF3. Those are the updated rifle levels, with RF3 sitting at the top. The 4s17M is certified under 0101.06, so its correct label is Level IV, not an RF rating. Plates certified to 0101.07 will carry their own listing. Threats tested beyond the NIJ round The reason many buyers look past the Level IV label is the rest of the test list. HighCom also lists the 4s17M against the DEA 2017 hard armor protocol rounds, including: 5.56x45mm M855 green tip 7.62x39mm mild steel core 7.62mm M80 steel jacketed FMJ .308 Winchester Core-Lokt Ultra Bonded .223 Remington Tactical Bonded Soft Point On top of that, HighCom lists it as Rifle Special Threats (RST) validated against additional rounds, among them 5.56x45mm M193 and M855A1, 7.62x51mm M61 AP, 7.62x39mm BZ API, 7.62x54R LPS and B-32 API, and a 12-gauge 1 oz slug. That M855A1 entry matters to some agencies, since it is a round many rifle plates are not rated to stop. The plate is also described as multi-hit. 4s17M sizes and weights HighCom offers the 4s17M in one shooters cut and five SAPI sizes, all multi curve: 10″ x 12″ shooters cut: 7.2 lb (3.3 kg) 7.25″ x 11.5″ SAPI XS: 5.5 lb (2.5 kg) 8.75″ x 11.75″ SAPI Small: 7.1 lb (3.2 kg) 9.5″ x 12.5″ SAPI Medium: 8.2 lb (3.7 kg) 10″ x 13.25″ SAPI Large: 9.4 lb (4.2 kg) 11″ x 14″ SAPI XL: 10.3 lb (4.7 kg) A front and back pair in the 10×12 shooters cut comes to 14.4 lb (6.6 kg) before the carrier. One detail worth knowing: HighCom notes the 10×12 shooters cut is nominally 9.5 x 11.5 inches, so check carrier fit against those dimensions, not just the label. Construction and warranty The plate uses a ceramic strike face over a composite backing, wrapped in a 1000D CORDURA textured nylon cover. Thickness is 0.95 inches (24 mm), and it is made in the USA. HighCom warranties the ballistic materials for 10 years and the exterior cover material and workmanship for 1 year. For procurement planning, that 10-year figure is the number to build a replacement cycle around. Who tends to issue the 4s17M Which plate suits a given role is a decision for each agency’s own policy and training staff. This post covers published specifications only. With that said, here is where the 4s17M’s specs tend to line up with buyer needs: Agencies that want armor-piercing protection: the 0101.06 Level IV rating and the M61 AP and M2 AP test rounds are the core reason to choose it over a Level III plate. Federal and task force work tied to DEA requirements: DEA Hard Armor Protocol compliance is stated directly on the spec sheet. Teams sizing a mixed roster: five SAPI sizes plus the shooters cut make it easier to fit officers of different builds from one model. Buyers balancing weight and threat level: at 7.2 lb for a 10×12, it sits between lighter Level III plates and heavier Level IV options. The trade-off is weight compared with Level III. If your threat assessment does not call for armor-piercing protection, a lighter Level III plate may be the better issue item. That is a judgment your agency makes from its own risk picture. Before you order A few checks save headaches later: Confirm the exact size and cut on the NIJ Compliant Products List if your policy or grant requires CPL-listed armor Match the cut to your carrier. Shooters cut and SAPI plates fit differently, and a 10×12 carrier will not hold an 11×14 SAPI XL Plan for the 10-year ballistic warranty when setting replacement dates Ask about volume pricing if you are buying for a full unit Sourcing the 4s17M through Arctos Arctos Industries is an authorized HighCom Armor dealer.

The HRT RAC, HRAC and LBAC all take the same placards and standard 10×12 SAPI-style plates, so the choice comes down to three things: how the back panel attaches gear, whether the shoulder straps release, and how much load the cummerbund is built to carry. The HRAC is the simplest of the three, the RAC adds HRT’s zip-on back panel system, and the LBAC adds a rigid load-bearing chassis for heavier kits. If you are outfitting a patrol unit, a tactical team, or just yourself, here is how the three actually differ, using HRT’s own published specs. Where the three carriers differ The differences are narrower than most people expect. All three are built from 500 denier Cordura, and HRT notes that every one of its carriers accepts its placards and most 10×12 inch SAPI-style plates. So whichever carrier you choose, the front of your kit stays interchangeable. What changes is the back, the shoulders and the cummerbund: HRAC: MOLLE webbing on the outside of the rear plate bag, non-detachable shoulder straps, basic cummerbund strap included RAC: proprietary rear that takes HRT’s Full and Half Zip-On Back Panels, a releasable shoulder buckle that can be moved to either side, basic cummerbund strap included LBAC: dual-zipper rear that takes the same zip-on panels, dual quick-release shoulder straps, and a rigid quick-release cummerbund built for load bearing The HRAC and RAC can both be upgraded with HRT’s 2-Band and Quick Release cummerbunds. The HRAC: the stripped-down option The HRAC is HRT’s no-frills carrier. It is double stitched, and the rear plate bag carries MOLLE webbing instead of a zipper system. That MOLLE rear is the main trade-off. You can mount pouches directly to it, but HRT’s zip-on back panels will not attach without its separate Zip-On Panel MOLLE Adapters. The shoulder straps are also fixed rather than releasable. For buyers who want a light, simple carrier and plan to run a fixed back setup, that simplicity is the point. It is also typically the lowest-priced of the three. The HRT RAC plate carrier: built for swapping back panels The RAC started as the HRAC with one major change. When HRT released it in 2019, it was described as the HRAC with the addition of the MultiZip dual-zipper back panel attachment system. That back panel is the reason to choose it. With two YKK zipper sections on the rear, you can swap between HRT’s full and half zip-on panels as the task changes, without re-weaving MOLLE straps. The shoulder strap buckle is releasable and can be set to either side, and the Cordura is treated with DuPont Teflon. The LBAC: when the load gets heavier The LBAC (Load Bearing Adaptive Carrier) is built around a different idea. Instead of a soft cummerbund, it uses a stiffened, ultra-lightweight cummerbund core that HRT says spreads weight across the whole torso, moving load away from common pressure points. Key specs from HRT: Chassis fits torsos from 30 to 50 inches by default, and up to 58 inches with the XL core Rigid quick-release cummerbund included Dual quick-release shoulder buckles, configurable for right- or left-handed users or removed entirely The cummerbund core can be run slick or fitted with sleeves (side plate sleeves and large MOLLE sleeves are sold separately) Airflow channel on the inside, with optional Velcro pontoons or spacers Integrated Duraflex chest buckle system for quick add-ons through HRT placards HRT describes the LBAC as being as close to “one-size-fits-all” as it can get, which matters if you are issuing carriers across a team with a wide range of body sizes. The trade-off is cost, since it is the most expensive of the three. Plate sizes HRT carriers accept All three take standard 10×12 inch plates. The LE or Large carrier fits 10×12 or SAPI Large plates, and the XL version of the RAC and LBAC fits 11×14 or X-Large SAPI plates. Before ordering, check that your plate’s cut and size match the carrier. A 10×12 carrier will not hold an 11×14 plate, and SAPI cuts differ from shooter’s cuts.

Picking the best HRT plate carrier for patrol There is no single answer, because it depends on what your officers carry and how your agency issues gear. Which carrier suits a given role is a decision for each agency’s own policy and training staff. This post covers published specifications only. What we can say is how the specs line up with common buying priorities: Lowest cost and simplest setup: HRAC. Fixed straps, MOLLE rear, nothing extra to learn. Back panel flexibility: RAC. One carrier can run different zip-on panels for different assignments. Heavier loadouts and a wide range of body sizes: LBAC. The rigid cummerbund and 30 to 58 inch torso range are built for it. If you want a deeper look at why HRT’s placard and zip-on ecosystem works the way it does, we covered that in what makes HRT carriers and LBE different from every other brand. Warranty coverage HRT backs its gear with a lifetime warranty against manufacturing and materials defects. It applies to the original purchaser and is not transferable, which is worth noting if your agency reissues carriers between officers.
