The photo pictured above is a picture of a pre-production prototype of the forthcoming Leitner-Wise Manufacturing "ambidextrous fire controls" system. LWM is run by Paul Leitner-Wise, an English-born engineer and designer who may be the best thing to come out of England since Henry Nock. You may remember Paul from the storied institutions known as LWRC (Leitner Wise Rifle Company).
The new ambi selector is just the latest of many new projects coming from LWM. Machined from billet and then Nitrided, it will have a full lifetime warranty and are designed primarily for use with gloves. To that end the levers are short, so as to avoid interference with a trigger finger, and the edges deburred so they provide sufficient 'grab' without sharp edges. The Nitriding is done to provide lubricity to the operations. Color is the result of the manufacturer's in-house heat treatment.
This is a 3D rendering of what the production model will look like. Note: production models will be broached so the lever arm cannot rotate; set screws will lock into the barrel. You would be wise to watch LWM not just for this system but for other innovations - their 'redefined' handguards, for instance. You can do so here.
The LWM ambi fire control system should be available on their website in approximately 2 weeks.
