Magpul whereby Bushmaster would take over production, future development and sales of the Masada. [Magpul Comments: Bushmaster ACR http://ar15.com/forums/topic.html?b=2&f=124&t=158557] [Bushmaster press release: Bushmaster andMagpul Team to Bring Advanced Rifle to Market http://www.bushmaster.com/press_release_013108.asp] It is apatent pending self-loading rifle platform designed byMagpul Industries ofErie, Colorado . The rifle was initially developed over a period of four months, completely independent of government funding. Prototypes were displayed at the 2007SHOT Show inOrlando, Florida . Originally scheduled for release in the second quarter of 2008, Bushmaster announced on May 16, 2008, that the consumer release would be delayed until Q1 2009, due to a focus on military projects [ [http://www.bushmaster.com/acr_update.asp Bushmaster ACR Update] ] .Design
The original Magpul Masada design represents an amalgamation of several recent rifle designs, incorporating what is considered by its designers to be the best features of each in a single, lightweight, modular rifle platform. [ [http://www.defensereview.com/modules.php?name=News&file=article&sid=975 Defense Review - MagPul Masada Adaptive Combat Weapon System (ACWS) Makes Its Debut ] ] Design features from the
Armalite AR-18 (short-stroke gas system), theFN SCAR (upper receiver, charging handle location), theHeckler & Koch G36 /XM8 (liberal use ofpolymer components), the M16/AR15 (trigger pack), and the M16 (barrel , fire control group) are clearly prevalent. The rifle also includes several features developed byMagpul , such as a quick-change barrel/trunnion system, adjustable gas regulator, reciprocating/non-reciprocating charging handle (depending on user actions), integral flip-up front sight, and storage compartments located in the stock and grip. [Magpul Industries [http://www.magpul.com/Masada_inside.pdf Masada Marketing Flyer] ] Just prior to the deal with Bushmaster, Magpul made additional changes to their design - the most obvious of these is the relocation of the ambidextrous operating handle to a forward position (somewhat similar to theHeckler & Koch G3 andHeckler & Koch MP5 series of weapons). Experts from Magpul Industries have on several occasions mentioned that depending on the barrel length of the weapon, the rate of fire is estimated to be in the range of 600-800 rpm (this is an estimate; specifics have not yet been verified).The magazine conceived for the 5.56 mm version of the Bushmaster ACR rifle is called the
PMAG , a high-impact, 30-round polymer magazine claimed by the manufacturer to be significantly more resistant to wear, shock, and harsh environments than other counterparts on the market. The PMAG isSTANAG 4179 -compatible, as it will readily fit any STANAG magazine firearm, including theM16 rifle family. [ [http://www.defensereview.com/modules.php?name=News&file=article&sid=975 Defense Review - MagPul Masada Adaptive Combat Weapon System (ACWS) Makes Its Debut ] ] The Bushmaster ACR's modular construction even allows the user to fire the7.62x39mm round depending on the choice of parts.Availability
The Bushmaster ACR is currently slated to be available in the first-quarter of 2009 with it being unveiled at the 2008
SHOT Show . It is anticipated that the rifle will have aMSRP starting at $1,500 with semi-automatic versions available to the consumer market, andselective-fire versions available for military and law enforcement.

The rifle was originally named after the
Siege of Masada . Magpul company literature about the rifle states that, "Magpul Industries is not Jewish owned or Israeli backed, however Magpul has always found the story of the Masada as a bold example of defiance." [Magpul Industries; [http://www.magpul.com/pdfs/masada_technote.pdf Masada Press Release] , January 2007] When production rights were signed with Bushmaster, the Masada name was dropped from the product.ee also
