Magpul Industries was founded in 1999 by Richard M. Fitzpatrick, a Force Recon sergeant with the US Marine Corps. The company has two divisions: Magpul Industries, which manufactures firearms accessories and Magpul Core which was founded in 2008 as Magpul Dynamics. Magpul Core provides firearms training and produces instructional videos.
