The Core M4 Bio-Reactor Ultimate Titanium Stove is a mini version of the full sized Core 4 Bio-Reactor Ultimate Stove. It's a great performer and only weighs 9.7 oz assembled! It's made from Titanium, packs nearly flat (except for the afterburners) and its so light you almost don't know it's there. It's just the right size to support smaller sized cook pots without extra parts but strong enough to support a full sized dutch oven.
The M4 is 6 inches tall so its got a great stovepipe draft that helps to continously suck fresh oxygen into the heart of the fire. The M4 doesn't get all clogged up with charcoal after a few minutes of use either. It's perforated burn plate has been tuned (through much trial and error) with just the right amount of holes to allow the stove to be self cleaning while still holding heat in the burn chamber to ignite damp wood better and use fuel conservatively. The M4 can run a full log's worth of kindling through it without cloging up with charcoal for continous cooking.
The M4s' Bio-Reactor feature uses a TLUD plate to restrict the free flow of its exhaust and compound the heat in its core like a reflection chamber and then re-burns its own exhaust to get the cleanest, hottest burn possible. It also helps ignite fresh fuel faster than an unrestricted draft 'fire in a metal box' type stove. Re-designed pot supports with larger teeth allow flames to flow against the pot on their way out to get the most heat out of the fire.
The Ultimate kit includes a 'Complete Rocket Port' that helps keep fuel dry in damp conditions, helps dry fuel as its fed into the combustion chamber, keeps it organized and up off the ground and directs heat that would normally be lost out it's fuel port back into the stove. It works great for adjusting the heat by sliding fuel in or out of the burn chamber without allowing coals to get all over the ground. The Ultimate kit also comes with a 'Heat Shield' that installs into the bottom of the stove. It's designed to protect the ground from heat damage, allow airflow under the stove and to allow the stove to be used on top of the snow. The Heat Shield also doubles as a griddle so you can cook your flapjacks or use it under your pot to keep soot off of your pot! (It's much easier to clean soot/tar off the griddle than a pot :)
Alcohol Stove Support
In case you're not able to find any dry wood, the M4's top TLUD plate also supports a Trangia, Esbit or Evernew alcohol stove at the optimum distance from your pot by setting it in the TLUD plate opening.
Triangle Burn Plate
The Core M4 now comes with triangle burn plate so that it can be transformed into a three sided ultralight stove just like its big brother the Core 4. It makes a really small stove but add the rocket port and it works really well for heating water and making coffee.
Don't forget the Grill! The M4 Ultimate kit comes with an ultralight titanium grill that locks onto the stove for grilling or it can be used to support smaller pots. It has straight lines for easy cleaning and it stores in the stove bag with the stove.
If you're looking for a single mid sized stove that you can absolutely depend on in just about any situation that will never leave you feeling underprepared or let you down, the M4 Ultimate is it.

Core 4 (left) size comparison to the Core M4 (right). Just the right size to support smaller pots, but puts out just about as much heat as a full sized Core 4.
Core M4's (right) high cleanout burn plate reduces charcoal buildup and keeps fresh air flowing.
