Modular Driven Technologies LP. (dba MDT LP.) was founded in 2009 by Laszlo Klementis who wanted a tactical chassis for his rifles with AR-15 ergonomics. With a background in CNC machining, he started to manufacture his own. As an avid competitor in service rifle, precision, and F-Class he started looking for something in the market which was not available. With input from a number of others, he ended up with the TAC21 Chassis which takes any AR-15 buttstock and pistol grip and increases accuracy by as much as 28%.
