A magazine carrier on the belt needs to do three things well: present the magazine at a consistent angle for a fast index grip, retain it securely through movement and exertion, and mount to the belt without shifting or rocking during the draw. The T.REX Ragnarok Mag Carriers — available in both pistol and rifle variants — are the heavy-duty, competition-and-duty-oriented carriers in the T.REX lineup, built from thick .125” Kydex and designed to pair with war belt and outer belt rigs rather than concealed-carry setups.
Background: From MARS to Ragnarok
The Ragnarok Mag Carriers are an evolution of the earlier MARS carrier system. They share the same fundamental mounting-hole pattern and material philosophy, but introduce improved shell geometry that better accommodates esoteric and metal-bodied magazines that the original MARS shells sometimes struggled to fit cleanly. If you are already running MARS carriers with common Glock or double-stack polymer pistol mags, or standard AR-15 PMAGs, the existing carriers work fine and an upgrade is unnecessary. The Ragnarok carriers become the clear choice when building a new belt, when running less common magazine types, or when standardizing on the current-production design.
Pistol Mag Carrier
The Ragnarok Pistol Mag Carrier is precision-formed from .125” Kydex — noticeably thicker and more rigid than the .093” Kydex used in the Ironside OWB carriers, which are designed for concealed OWB carry with integrated belt loops. That thickness matters: a duty or competition mag carrier takes repeated hits from aggressive reloads and gets yanked at odd angles during dynamic movement. Thicker Kydex resists deformation over time.
The carrier supports magazines in either a rounds-forward or rounds-rearward orientation. Rounds-forward is the recommended default because it sets up a natural index grip — the index finger falls along the front of the magazine body and guides it into the magwell without fumbling. The modular hole pattern allows rotation in 15-degree increments in any direction, so the carrier can be canted to match your specific draw preference and belt position.
Retention is fully adjustable by tightening or loosening the hardware that clamps the Kydex shell. This allows the carrier to be tuned for each specific magazine: tight enough that the mag stays put during a sprint or a prone position, loose enough that a firm upward pull frees it cleanly. Retention should be re-checked whenever the magazine type changes — different mag bodies have different outer dimensions and surface textures.
Rifle Mag Carrier
The Ragnarok Rifle Mag Carrier follows the same construction philosophy: .125” Kydex, modular hole pattern with 15-degree rotation increments, fully adjustable retention, and full ambidexterity. It is confirmed compatible with all generations of Magpul PMAGs as well as USGI, EPM, and other STANAG-pattern magazines. The improved geometry over the MARS predecessor is most noticeable with aluminum USGI mags and other metal-bodied options — the shell contours grip them more evenly.
Like the pistol variant, the rifle carrier can orient the magazine rounds-forward or rounds-rearward. For a belt-mounted rifle mag, rounds-forward again supports an index grip that feeds naturally into the magazine well, with the index finger riding the front spine of the magazine during the reload stroke.
Mounting: The Blade-Tech Tek-Lok
Both Ragnarok carriers are designed to pair with the Blade-Tech Tek-Lok as the primary belt attachment. The Tek-Lok is an interlocking clip system made from glass-filled nylon that clamps over the belt and locks in place, then releases with a thumb lever. It ships with nine mounting holes and adjustable belt-width shims — with shims installed it fits belts up to 2.25”; with shims removed, up to 2.5”.
A critical setup tip for anyone running a two-piece belt system like the Orion or Speed Belt: apply a strip of sticky-back Velcro (loop side) to the back face of the Tek-Lok so it grips the inner belt’s hook Velcro. Without this, the Tek-Lok can slide laterally on the outer belt during aggressive draws. This is a simple, cheap fix that makes the carrier feel anchored.
If you select the Tek-Lok option at checkout, it ships pre-installed on the carrier — no fitting required out of the box.
How the Ragnarok Fits the Belt Ecosystem
The Ragnarok carriers sit within a broader ecosystem of belt-mounted magazine solutions. Esstac KYWI pouches use a laminate-stiffened Kydex insert inside a cordura shell, producing a different retention feel and a slightly bulkier profile. Blue Force Gear Ten-Speed pouches collapse flat when empty, which is useful for low-profile rigs but offers less positive retention than a rigid Kydex shell. The Ragnarok carriers occupy the rigid, open-top, fully-adjustable end of the spectrum — the same design lineage as the Ragnarok OWB holster itself.
For the Speed Belt specifically, the MARS/Ragnarok carriers were highlighted as the preferred system because they allow easy repositioning along the belt’s MOLLE pass-throughs and can be added or removed quickly when reconfiguring for different training sessions or match stages. Users running DMR-oriented setups with 7.62 magazines can pair the rifle carrier with ITW-style fast-mag options to handle the larger magazine body.
Mounting Options Beyond the Tek-Lok
The Ragnarok carriers use the same Safariland-compatible hole pattern found on the Ragnarok holster line. This means the same family of Safariland belt mounts — the hi-ride belt slide, the paddle, and the UBL mid-ride — can technically be used with these carriers if your use case demands it. The QLS (Quick Locking System) can also be attached to any Safariland-pattern mount, enabling rapid swap-on/swap-off capability without rethreading hardware. In practice, the Tek-Lok is the most popular choice for mag carriers because it is lower-profile than a UBL and faster to install than a belt slide, but the option exists for users who want to standardize their entire belt on QLS.
Configuring Carrier Placement
Where the carriers sit on your belt matters as much as which carriers you choose. For a general-purpose war belt, a common configuration places the pistol mag carrier on the centerline of the non-dominant hip (roughly the 11 o’clock position for a right-handed shooter), with rifle mag carriers forward of that toward the belt buckle. This keeps pistol reloads close to the holster-side hand’s natural reach and rifle reloads accessible to the support hand. See Pistol Mag Carriers on the Belt and Rifle Mag Carriers on the Belt for detailed placement guidance.
The belt’s magazine loadout also has a direct relationship to what is carried on the chest rig or plate carrier placard. The belt typically carries reload magazines for immediate access, while the placard carries sustainment magazines. Thinking about these two layers together — rather than configuring them independently — prevents duplication and ensures you are not over-indexing on one magazine type while neglecting the other.
Training Considerations
Consistent presentation from a mag carrier is a perishable skill. The carrier angle, retention tension, and belt position all need to become automatic through repetition. Drawstroke development applies as much to the reload stroke as it does to the initial draw — the hand has to find the magazine, acquire an index grip, extract it cleanly, and deliver it to the magwell without visual confirmation. Dry fire practice is the most efficient way to build this motor pattern before confirming it with live fire.
