When Safariland and Haley Strategic Partners introduced the BASELINE belt and accessory line, what immediately caught my attention about the pouches was the philosophy behind the system. Rather than adding complexity for the sake of innovation, the BASELINE series focuses on creating a durable, lightweight, and dependable platform for law enforcement, competitors, instructors, armed citizens, and everyday shooters alike.
The BASELINE accessory line includes a 5.56 magazine pouch, a single pistol mag pouch, a double pistol mag pouch, a dump pouch, and the Mandible Vertical MOLLE Strap and Mandible Angled MOLLE Strap attachment system.

All mag pouches come standard with Mandible Vertical Straps that fit two-piece belts with a 1.5- to 2.0-inch outer belt.

First Impressions
Most belt-mounted equipment relies on MOLLE/PALS, Malice clips, or hook-and-loop solutions such as VELCRO® BrandOneWrap. While those methods work well, reconfiguring gear can be time-consuming.
The BASELINE system approaches attachment differently. The pouches, mounting hardware, and belt interface work together to support quick configuration changes while maintaining a clean, low-profile appearance. What stood out to me from the start was how cohesive everything felt.
MP2 Mag Retention Insert System
The rifle and pistol pouches use Haley Strategic’s MP2 retention insert system. This molded polymer insert provides passive retention with a click-in hold you can hear and feel. The insert installs either way, so magazines can ride “bullets out” or in the traditional “bullets forward” orientation, whichever the shooter prefers.

Unlike traditional pouches that depend on bungee cords, flaps, or adjustable shock cord, the MP2 insert serves as the primary retention mechanism. The result is a streamlined design with fewer external components.
Why the MP2 Insert Matters
Magazines remained secure during movement drills while still allowing smooth access during reloads. Even when purposely shaken vigorously upside down, the magazines didn’t budge. I tested both polymer and steel mags.

The insert also helps the pouch maintain its shape, making one-handed reindexing easier than with many soft-sided pouch designs that tend to collapse after a magazine is removed.
Perhaps the biggest benefit is consistency. Whether I was using the rifle pouch, single pistol pouch, or double pistol pouch, retention characteristics and magazine presentation remained largely the same. That predictability helps build confidence during reloads.

BASELINE 5.56 Magazine Pouch
The 5.56 Magazine Pouch is built around the MP2 insert. During testing, magazine presentation remained consistent, retention was secure during movement, and one-handed reindexing was straightforward.
BASELINE Single and Double Pistol Magazine Pouches
The Single Pistol Magazine Pouch is aimed at users looking to minimize belt real estate while maintaining quick access to a spare magazine. Throughout testing, it consistently presented magazines in a repeatable orientation and remained stable when mounted with the Mandible attachment system.
The Double Pistol Magazine Pouch expands capacity while using the same MP2 retention technology and mounting interface. Even with the added weight of two loaded magazines, the pouch remained secure during movement drills, reloads, and transitions.
BASELINE Dump Pouch
The BASELINE Dump Pouch follows the same low-profile design philosophy found throughout the accessory line. It uses a VELCRO® Brand ONE-WRAP hook-and-loop drop-down attachment, so it goes on and off quickly without taking up MOLLE space on a belt, chest rig, or plate carrier.
When stowed, it occupies very little belt space. When deployed, it provides more than enough room for magazines, gloves, tools, or miscellaneous range items.
It isn’t revolutionary, but it does exactly what a dump pouch should do without adding unnecessary bulk.

The Mandible Attachment System
While the MP2 insert system is an important part of the line, the Mandible attachment system is arguably the most distinctive feature. It bridges the gap between traditional MOLLE attachment methods and conventional hook-and-loop solutions. When attaching MOLLE pouches using the Mandible Straps, you are less limited by the PALS (Pouch Attachment Ladder System) grid.

Advantages Over Traditional MOLLE
Traditional MOLLE remains popular because of its durability and compatibility, but changing equipment placement usually involves reweaving straps or reinstalling hardware. Mandible MOLLE Straps use an extruded hook-and-loop laminate that also grips the inner belt.
During testing, the Mandible system offered several advantages:
- Faster pouch repositioning
- Lower-profile integration with the belt
- Excellent stability during movement and reloads
- Easier experimentation with belt layout and equipment placement
One of the most noticeable characteristics was how little movement the pouches exhibited once installed. Even during aggressive reload drills and positional transitions, everything stayed in place.

Angled Straps Add Flexibility
One of the more interesting features within the Mandible system is the availability of dedicated angled mounting straps. Available in both left- and right-hand configurations, these straps hold a compatible pouch at a fixed 45-degree angle, matched to the shooter’s gun hand.
The angled straps are compatible with the Single Pistol Magazine Pouch and other single-column MOLLE-compatible pouches, but not the Double Pistol Magazine Pouch or 5.56 Magazine Pouch. While not everyone will need them, they provide a simple and integrated way to fine-tune magazine orientation without relying on additional adapters or aftermarket hardware.

Mandible vs. One-Wrap
ONE-WRAP remains popular because it’s simple, affordable, and easy to install. However, during testing, I noticed several clear-cut advantages to the proprietary Mandible system for mag pouches.
Pouches remained consistently positioned throughout training sessions and equipment manipulation. Rifle magazine pouches and double pistol configurations remained stable under heavier loads, and pouch movement during magazine draws was minimal.
The Mandible attachment system also created a cleaner overall appearance.
Final Thoughts
The BASELINE accessory line represents a very well-thought-out integration of pouch design, magazine retention, and mounting hardware. It focuses on getting the fundamentals right.
The MP2 retention inserts eliminate the need for bungees, flaps, and frequent adjustment while still providing secure retention and efficient access. At the same time, the Mandible attachment system offers what I consider to be a better alternative to traditional MOLLE and hook-and-loop mounting methods, offering stability and ease of adjustment.
If you’re looking to build or upgrade a modern two-piece belt setup, the BASELINE system is worth a serious look.
The BASELINE MOLLE Belt and mag pouches are available in Black, Coyote, MultiCam, and Ranger Green. The Dump Pouch is available in Black, Coyote Brown, and MultiCam.
A Few Quick Answers on BASELINE Pouches
Most double-stack 9mm pistol magazines, including Glock 17/19/19X/34/45/47/22/23, Sig Sauer P226, Staccato P/C/CS/C2/XC, and other standard 2011 magazines, Smith & Wesson M&P9, Springfield Armory XD9/XD40/Hellcat, HK P30/VP9/USP9, and Walther PDP.
Nearly all of them, including USGI, PMAG, and STANAG-pattern magazines.
They mount to two-piece MOLLE/PALS belts, and their Mandible Vertical Straps are sized for outer belts 1.5 to 2.0 inches wide.
Vertical straps come with every BASELINE mag pouch. The Angled strap holds a pistol mag pouch at a 45-degree angle, comes in left- and right-hand versions, and fits only single-column pouches.
