Magpul Masada 5.56x45mm

The Masada concept was developed by Magpul’s Design Group. The initial Masada concept was first shown publicly at the 2007 Shot Show and its success prompted Magpul to spend a year redesigning the system for production.  The rights to this design were purchased by Bushmaster in 2008.  The Masada will never be put into production as Bushmaster purchased the rights to this rifle and later replaced this design with a new rifle, the Bushmaster ACR.
