American Defense Mfg Launches improved Gen III QD Auto Lock Lever Assembly

New Berlin, WI.  August 2018 – American Defense Mfg® is proud to announce the launch of our third generation, patented QD Auto Lock™ locking lever. This locking lever is included on all optical, illumination, and target acquisition device mounting solutions.

The Gen III lever assembly features a more robust lock and bolt engagement, a larger diameter lock pin, and a more pronounced textured lock to make it easier to press to release the lock.  In addition, a finer nut and bolt thread (8-40 2A) was incorporated to achieve better resolution when clamping.

“American Defense Mfg® always strives to make technology driven products and continuous improvements to its product line.  These improvements make what we feel is the best adjustable, locking lever on the market even better.” Said William Phebus, Director of Sales.

The Gen III lever was phased into the product line starting in May 2018.

There are some visual differences.

Here is what to look for:
• American Defense Mfg® Eagle logo on QD Auto Lock™ lever arm instead of ADM web address.
• A more pronounced lock that angles outward.
• Vertical knurling on lock for better user engagement.
