The Bushmaster Adaptive Combat Rifle (ACR) is the production name for an updated version of the Masada Adaptive Combat Weapon System. In late January 2008, Bushmaster entered into a licensing agreement with Magpul whereby Bushmaster would take over production, future development and sales of the Masada.[1][2] It is a patent pending self-loading rifle platform designed by Magpul Industries of Erie, Colorado. The rifle was initially developed over a period of four months, completely independent of government funding. Prototypes were displayed at the 2007 SHOT Show in Orlando, 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.[3] On November 18, 2008, Bushmaster released a statement saying, "The ACR is being redesigned to be a superior offering to compete for the next generation US Army infantry carbine and subcompact weapon requirement and will be available to select customers in 2009."[4] The ACR was one of the weapons displayed to U.S. Army officials during an invitation-only Industry Day on November 13, 2008. The goal of the Industry Day was to review current carbine technology prior to writing formal requirements for a future replacement for the M4 Carbine.[5][6]

Design

Magpul Masada, the design origin of the Bushmaster ACR

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.[7] Design features from the Armalite AR-18 (short-stroke gas system), the FN SCAR (upper receiver, charging handle location), the Heckler & Koch G36/XM8 (liberal use of polymer components), the M16/AR15 (trigger pack), and the M16 (barrel, fire control group) are clearly prevalent. The rifle also includes several features developed by Magpul, such as a quick-change barrel/trunnion system, adjustable gas regulator, non-reciprocating charging handle, and storage compartments located in the stock and grip.[8] 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 the Heckler & Koch G3 and Heckler & 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).

Bushmaster Firearms, with the help of Remington Arms (a sister company in the Freedom Group, Inc portfolio that includes Bushmaster, Remington, Marlin, and DPMS Panther Arms brands) has also made some design changes based on extensive environmental and functional testing specifically to meet the emerging requirements of the US military in both the carbine and subcompact weapon versions of the ACR family. It is expected that the rifle will be offered to military customers in 5.56mm NATO, 6.8mm Remington SPC, and 6.5 Grendel with the same lower receiver and the user just having to switch out the barrel, bolt face, and magazine to change calibers. It is also expected that the ACR will have barrel length options of 10.5″, 12.5″, 14.5″, 16″ (commercial), and 18″. The official name of the rifle for military use will be the Remington ACR.

The magazine conceived for the 5.56mm version of the ACR rifle is called the PMag, a high-impact, 30-round polymer magazine claimed by Magpul to be significantly more resistant to wear, shock, and harsh environments than other counterparts on the market. The PMag is STANAG 4179-compatible, as it will readily fit any STANAG magazine firearm, including the M16 rifle family.[7] The Bushmaster ACR's modular construction even allows the user to fire the 7.62x39mm round with an alternate barrel and lower receiver.

Availability

The ACR is stated to be available in the 2nd Quarter of 2010 for military, government and commercial customers. The ACR will be available in greater quantity (tens of thousands) in the commercial marketplace in 2010.[9] According to an official press release from Bushmaster, the rifle will have suggested retail price between $2,685 - $ 3,061.00[10] - twice as much as early price quotes of "around $1500," causing public outcry and dismay of the rifle from a large portion of the firearms fraternity and potential civilian end-users. Semi-automatic versions will be available to the commercial market from Bushmaster, and selective-fire versions available for military and law enforcement under the Remington name.[11] As of April 2010, civilian market rifles are available for sale. [12]

Miscellaneous

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."[11] When production rights were signed with Bushmaster, the Masada name was dropped from the product.
