Blending innovative technology and design with traditional tactical function, the QD-NVL (V2) by LeonWorx Solutions is a retention system for night vision devices that provides a solid lock and safety to otherwise very valuable sensitive items.

Using the sewable V-Buckle 25 by Fidlock, the V2 is the second version LeonWorx’s unique QD-NVL retention lanyard for securing night vision to helmets that uses a magnetized lift opening mechanism. This mechanism itself has a static breaking load of 588 newtons (a measurement of force), or 60kg (or 132lb) and can only be actioned if the proper lift angle is utilized.

At the base, the QD-NVL (V2) utilizes a double-layer panel of 2” (W) x 3” (L) 17337 Mil Spec solution-dyed Cordura nylon webbing, with hook-and-loop (male) on the bottom for attaching to corresponding hook-and-loop panels on helmets or covers.

On three sides of the QD-NVL (V2) are nylon pass-through loops for threading shock or paracord through for added security. Additionally, an elastic nylon cuff is behind the V-Buckle for spare battery storage.  

The fourth (front) side of the QD-NVL (V2) is reserved for a 1” tab that allots for shock cordage to attach to the night vision device, and can be adjusted via press-button slide lock.

Product Evaluation Scores:

• Cost – Good (4/5): With a list price of $44.99, the QD-NVL offers a unique locking mechanism to secure an end-user’s night vision device to their helmet’s preferred hook-and-loop panel or covers. Considering the dollar value of many night vision devices, any added security serves as a beneficial insurance against slippage or damage to the retention arm that could potential cause the night vision to fall off. The Fidlock buckle itself is a $25 value, and from a European company that specializes in biking and sport retention locks. The bottom of the QD-NVL also utilizes industrial hook-and-loop (male) to ensure positive connection. The closest market comparator to the QD-NVL would be the Nightvision Elastic Retention Device ($35) by Kinetic Consulting, or the SBL NVG Lanyard ($35) by T.REX Arms, but both are only a simple hook-and-loop panel and lack the mechanical locking mechanism of the QD-NVL. Wilcox does offer an NVG mechanical Lanyard ($68.14) but those are simple spring-tension lanyards that mount directly into specific helmet NVG shrouds. Thus, the QD-NVL (V2) is at a good price point amid the market, offering significant security over other retention lanyards with a balanced price for the hardware included.  
• Comfort – Good (4/5): From a comfort aspect, the QD-NVL (V2) was simplistic in approach, came pre-assembled, and attached easily. The industrial hook-and-loop did provide a noticeably stronger than typical connection to the corresponding panels on both the helmet and helmet cover. The locking mechanism of the V-Buckle 25 itself broke easily when the pull tab was pulled directly outward/up, but remained locked firmly when pulled forward (such as if the NVGs broke free of the mount and suddenly placed increased tension/load on the front of the device). The strength of the V-Buckle 25 was such that it could fully support the weight of a loaded helmet (i.e. with earpro, NVGs, light/accessories) freely and without any slippage. The magnetic element inside the base of the V-Buckle 25 allowed for easy realignment and rehoming of the release mechanism, without any measurable effort, to re-engage the lock.
• Durability – Average (3/5): With its base 17337 Mil Spec material made from double-layer solution-dyed nylon webbing, the QD-NVL (V2) had a somewhat pliable base that contoured to the curvature of the helmet easily. The fabric itself had typical (or average) abrasion resistance amid the nylon gear market, and held up with expected usage. Despite continual re-adjustment, the hook-and-loop (male) material, nor threading, showed any signs of premature wear or excessive fraying. Over time, the shock cord will need to be replaced simply due to exposure and wear (typical for this type of material). Otherwise, the V-Buckle 25 had a max load capacity of over 100 pounds and kept producing the same level of secure lock over the term of usage, and showed no signs of wear at the edges of the aluminum or weakening of the magnet.
• Functionality – Good (4/5): Functionally, the QD-NVL (V2) came down to a good level of added strength and retention as a safety backup to the NVG mount. The V-Buckle 25 locking mechanism was able to support the full weight of the overall helmet, while freestanding only off the locking mechanism’s pull tab—yet it still did not slip unless the tab was pulled as intended. Elsewhere, the elastic cuff for battery storage was initially very tight, but that was ideal considering it was the only measure securing the spare battery. It could easily fit other items like full-sized chemlight. The side nylon loops were intended for tying additional retention/paracord to the QD-NVL (V2) for added security, but without other accessories like a battery pack/Mohawk/earpro helmet mounts for hardpoint connections, they offered only slot space for mini chemlights. The only notable aspect from a negative functional perspective was that when the night vision was deployed downward, and the greatest level of tension was exerted on the shock cord and QD-NVL (V2), the rear edges of the nylon fabric would curl or pull on the helmet cover fabric. It was never enough to cause the hook-and-loop to begin separating, but noticeable because it displayed how that tension was being carried through the QD-NVL (V2). Those with the longer band of hook-and-loop on their helmets/covers will most likely experience less of this effect, unless positioning the QD-NVL (V2) further to the rear of the helmet, and thus placing more tension on the cordage and body of the locking mechanism. A recommendation to LeonWorx would be to consider adding a grommet at the rearward portion of the QD-NVL (V2) so that it could serve as an alternative tie-down point if the nylon loops were otherwise not available.
• Weight – Average (3/5): Weighing in at 1.8 ounces, a majority of the (minuscule) weight to the QD-NVL (V2) was from the overall double layer of 17337 nylon and shock cord. The retention lanyard as a whole was not noticeable when mounted on the helmet, did not shift, nor was unbalancing. However, the inclusion of a mechanical locking mechanism (rated to over 100 pounds) added slightly to the overall product weight as opposed to only a hook-and-loop panel. In contrast, the Nightvision Elastic Retention Device (0.50 ounces) by Kinetic Consulting, or the SBL NVG Lanyard (1.0 ounces) by T.REX Arms illustrate that use of only hook-and-loop retention panels are slightly lighter, but they also only have a rating to approximately 50 pounds. The Wilcox retention lanyards are similarly only 0.50 ounces and have a breakaway rating of 12 pounds, but necessitate direct mounting to an NVG shroud. Thus for the minimal addition in weight, the QD-NVL (V2) still offered superior retention levels and was an appropriate (or average) balance between all market alternatives and designs.

Overall Rating – Above Average (18/25)

I was first introduced to the concept of a “boom bag” amid one of my many overseas adventures, and since then it has been a mainstay of my time at the range. Done right, a boom bag (or satchel bag) can be a versatile and essential piece of every-day gear that has a wide array of applications.

The premise of a boom bag is pretty straightforward. They are small packs or bags that hold spare magazines (loaded or unloaded), loose ammo, grenades, aid kit, or whatever is essential for the mission at hand. The idea being its a bag that can be grabbed and thrown into use without a jumbled mess inside – where everything is easily accessible and secure. They need to be durable enough to last hard use, but not so bulky as to rival the added weight of another rucksack. Lots of folks use the typical range bag or every day carry bag to fulfill this role; but as I found, not all bags are equal.

After quite a bit of research, I came across S.O. Tech Tactical and their Mission Go Bag (MGB).

The S.O. Tech MGB was introduced circa 2005 as a trauma bag, then revamped in 2015 as an A1 model with added features that celebrate S.O. Tech’s 10 years as the choice pack by US Special Operations. Its size makes it ideal as a medical bag, carrying radios and batteries, breaching tools, E&E components or anything you could need for the task at hand. Designed by founder Jim Cragg based on his own experiences in the military, the MGB offers two main compartments, smooth zipper closure, and 12 different carry configurations—but its real advantage is in its well-thought-out design.

Unlike its contemporaries, the MGB’s main compartment has a deep opening, so that when accessing the contents everything is visible in a single look (something that in a high stress situation can be critical). Inside the main compartment are four side pockets with drawstring and cinch closures. This allows you to keep an assortment of loose items or packages secure and separate from the rest of the contents in the main compartment. For example, if viewed for a medical purpose this design enables the MGB to have dedicated and secured pockets for Israeli dressings, hemostatic agents, bandages, and other aid elements while still leaving the main pocket compartment available for other use. The main compartment also features a divided sleeve along the back that can keep maps, notebooks, or other legal-sized documents.

The secondary compartment on the front is accessible via another zipper closure, and has two, eight-slot MOLLE panels stitched to the outside. Inside, the secondary compartment is rather straightforward with a legal-sized storage area and a Velcro panel for adding secondary accessories with a similar backing.

Another unique feature about the MGB is its ability to adapted to 12 different carry configurations that include:

• Backpack
• Belt pack
• Brief case
• Chest pack
• Pack mount
• Satchel
• Sling pack
• Vehicle wall pack
• Vest mount
• Waist pack

On the whole the MGB is amazingly versatile regardless of how you intend to use it. The 500D Cordura nylon construction gives it a proper blend between durability against hard use, and flexibility that allow it to conform against the body or pack as needed. On the back, the rubberized pad proved to be a lifesaver in preventing heat rash or excessive movement of the pack. The only noted negative was the shoulder strap itself may need some more padding given its width. In any of the over-the-shoulder methods you may find it rubs exposed skin a little raw. In addition, the handle straps don’t have significant padding to be carried as a briefcase throughout the day.

Product Evaluation Scores:

• Cost – Average (3/5): At $130 the MGB is at a price point comparable to other packs on the market of similar size. For an additional $10 you can get a special operations edition with embroidery.
• Comfort – Good (4/5): The MGB was surprisingly comfortable in many of its configurations, especially as a backpack. However, lack of support material in the handle as a briefcase, and strap for over-the-shoulder use gave it negative marks.
• Durability – Excellent (5/5): The 500D Cordura material is very puncture and scratch resistant. It won’t stop a blade attack or isn’t bulletproof, but it will hold up against dragging, pulling, or field use extremely well.
• Functionality – Excellent (5/5): The number of carry configurations make the MGB extremely adaptable, for any mission or role.
• Weight – Good (4/5): The bag itself is merely 1.5lbs, but you can fit a lot more weight into it than that. Each pocket in the main compartment holds approximately 1k lose rounds of 9mm, or roughly 800 rounds of loose 5.56/.223, so it can carry a good amount. Your largest limiting factor on weight will be having to carry what you put in it.
• Overall Rating – Very Good (21/25)

Revised for its release, the 2020 version of the Stinger line is one of the brightest handheld lights offered by Streamlight. It features improved ergonomics, electronics, and rechargeable batteries that make it an excellent addition at home or on the job.

With its 7.67” overall length and diameter of 1.62”, the Stinger 2020 comprises of an aircraft-grade aluminum alloy body with an anti-roll design, and ergonomic features (such as a notched body and rubberized grip panels) that help maintain a solid hold.

The Stinger 2020 has dual ON/OFF power switches (one on the head, and one on the tail cap) with a selectable output switch of Low, Medium, High. The external Function switch has a set-it-and-forget-it feature where the selected output remains selected until the user changes it.

Producing up to 2,000 lumens of light, the emitter in the Stinger 2020 can be adjusted based on the individual’s needs; Low (100 lumens) with a 70m beam, Medium (850 lumens) with a 200m beam, or High (2,000 lumens) with a 315m beam. The emitter itself is protected behind a high-temperature tempered Borofloat^® glass lens with the internals sealed against moisture (with an IPX7 immersion rating) and corrosion behind a single body design and rubberized gaskets at all access points.

The power source for the Stinger is a SL-B26^™ USB rechargeable battery pack, which can be integrated with pre-existing Stinger smart chargers (while the battery is inside the light), or with USB power cables or a Li-ion battery bank charger. Depending on the selected output, the SL-B26^™ battery will provide varying runtimes between 24 hours of continual use on Low, or up to 2 hours of continual use on High. The Stinger also has a strobe feature (High burst) with a runtime of 3.25 hours.

The Stinger 2020 also includes a wall-mounted charging station that connects to the SL-B26 via through-current connection points and ensures that the handheld light is always ready for use. Included is a separate charging cable specifically to charge the SL-B26 batteries directly.

The Stinger 2020 is available in only in Black (featured).

Product Evaluation Scores:

• Cost – Average (3/5): With an MSRP at $150.30, the Stinger 2020 offers a 2,000 lumen output in a robust handheld light for personal or field use. The material makes the new Stinger flashlight extremely resistant to impact, while its rechargeable power source offers a number of ways to ensure the light is always ready for use. Market alternatives for similar handheld lights would be the ML150LRS(X) @819 lumens ($124) by Maglite, or the MH40GTR @1200 lumens ($129) by Nitecore. So, it is a balance whereby the Stinger 2020 offers some of the highest lumen output for a handheld of its size and function, but its recent release with newer technology makes it one of the more expensive at an appropriate (or average) price point amid the current market, and one the consumer should consider as an equal balance.
• Comfort – Good (4/5): From a comfort aspect, the Stinger carried well—not being excessively heavy nor under/over balanced on either end. The notched and rail body features allowed for the Stinger to be comfortably carried, and gave good purchase for positive control while using. The textured rubberized grip panels along the side of the body also added in positive control by giving the hand a rougher surface to feel and hold. The ON/OFF and Function switches had a clear tactile and audible sensation by which it was easy to recognize what setting was currently in use. The adjustable light output helped prevent the light from being over powering, and potentially blinding when use in hours of darkness, in the field, or on the family camping trip. It should be noted, that the strobe feature was effective in momentarily blinding an individual when they looked at the light source.
• Durability – Good (4/5): The Stinger was made from the usual aluminum alloy body and bezel as other Streamlight products, and it survived the drop test (five drops from varying angles) just fine and sustained only superficial marring to the body, edges, and bezel. The thick Borofloat^® glass lens is widely used throughout Streamlight’s products and continued to hold up well against impacts directly to the emitter. While the ON/OFF switches did give good tactile feel through the rubberized protective material, over use/time/sun exposure it is likely this will be the first element of the flashlight to fail—something common to that kind of design. 
• Functionality – Good (4/5): Functionally, the Stinger 2020 was great in performance and lumen emission. Used on the range and in camping trips, the light’s high output easily cut through dust and other photonic barriers. The light did come out as a brighter “white” light vice “warmer” tactical lights that often penetrate those barriers to a further extent. But the variable function switch proved invaluable in situations requiring less light and the ability to switch between the three settings really was an advantage. While its overall length was comfortable as a handheld flashlight, the rear ON/OFF button couldn’t be comfortably reached when used single-handed in a tactical setting so the rear button’s location wasn’t used nearly as frequently as the alternative closer to the front of the light. One minor issue included the wall-mounted charging station that came with the Stinger 2020. It readily provided a full charge to the flashlight quickly, but the retaining prongs that engaged and retained the flashlight’s body while mounted were very tight, making quick removal difficult when needed. Obviously this was a tradeoff in keeping the light secure and connected to the recharging prongs, but something to be aware of in contrast to other wall mounts that maybe keep a looser hold. Perhaps one feature recommended to Streamlight in future versions of the Stinger would be a focal adjustment feature whereby the user can adjust between a focused point of the light’s output, and a wide-angle dispersal for broader throw of coverage, as is the Stinger offers only a focused point. Additionally, it might be nice if the Stinger 2020 came with a rudimentary belt loop, clip, or other accessory for mounting it (aside from the wall mount)—as is the nearly 8” flashlight didn’t come with any means of retention.
• Weight – Average (3/5): Weighing in at 12.30 ounces (with battery pack installed) the Stinger did have a little heft to its feel. This is directly attributed to the volume of aluminum used and normal within the market of similar lights. The weight however wasn’t significantly uncomfortable enough by itself to detract a waist packs or worn on a belt. In contrast to the noted market alternatives above, the ML150LRS(X) @819 lumens (11.2 ounces) by Maglite, or the MH40GTR @1200 lumens (13 ounces) by Nitecore show that the Stinger is well within the appropriate (or average) weight range for similar products.

Overall Rating – Above Average (18/25)
