The Maelstrom MMS (formerly known as the 4Sevens Maelstrom G5) follows FOURSEVENS' design philosophy of "function over form." From the start, the Maelstrom MMS was conceived with these basic goals:
The seven output modes that the Maelstrom MMS offers are easily accessible by simply rotating the head of the light. A completely silent 4-point switch allows selecting through the modes without detection, ideal for tactical situations. The seven modes are split into two sets. The most commonly used modes of output are placed as the first two positions (tight and immediately loosened) for both sets of modes: Max/Strobe, and High/Medium. A "clicky" switch is fully exposed in the tailcap for easy access, even when wearing gloves. Like many tactical flashlights, the Maelstrom MMS has a "momentary-on" feature that is accessed by just lightly depressing the tailcap.
Moonlight (0.2 lumens, 7.5 days)
Low (28 lumens, 22 hours)
Medium (200 lumens, 3.1 hours)
High (420 lumens, 1.3 hours)
Strobe (2.7 hours)
Beacon (30 days)
S.O.S. (8.5 hours)
The Maelstrom MMS has a crenulated stainless steel strike bezel that is replaceable with a flat bezel. The grip/anti-roll ring that comes with the flashlight is also replaceable with a flat one. Generous knurling throughout the surface of the entire light ensures confident grip even in the messiest of situations. A shock-mounted battery design holds the batteries firmly inside to the body of the light, avoiding self-destructive battery movement. The light is ready to be weapon mounted. A patent-pending anti-rattle design that accommodates either 2 CR123A batteries or 1 18650 battery without the need of spacers or adapters.
The Maelstrom MMS includes a custom molded carry pouch designed to help retain the light even when flap is open. It also includes a spare flat bezel, a spare flat grip ring, a lanyard, a split keyring, spare o-rings and 2 CR123A batteries. The flashlight's lens is also made of optical-grade glass, ensuring good light transmission.
FOURSEVENS flashlights come with a 10 Year Warranty against defects! Such an outstanding policy shows that FOURSEVENS is a company you can trust.
The Maestrom MMS features a unique 4-point switch engagement in the head of the flashlight that lets you select the different outputs smoothly and silently by simply loosening or tightening the head. Every quarter-turn (approximately 90 degrees) of the head selects a different output.
As you loosen or tighten the head, you change modes as follows (in order of Loosened to Tightened): Off, Auxiliary 2, Auxiliary 1, Secondary, Primary.
The Maestrom MMS's modes of output are split into 2 sets, Regular and Special. The following are the modes in order from Auxiliary 2 to Primary (Loosened to Tightened):
Regular: Moonlight » Low » Medium » High
Special: Beacon » S.O.S. » Strobe » High
As you can see, switching between the modes in a set is very simple - you just tighten or loosen the head to get to your desired mode.
Switching between sets is also simple. Fully tighten the head of the flashlight so that you are in the Primary mode. Then, quickly loosen and tighten the head (switching between Secondary and Primary) 4 times to change to the alternative set of modes.
