The Adaptive Combat Rifle (ACR) is the production name for an updated version of the Masada Adaptive Combat Weapon System. It is an assault rifle platform designed by Magpul Industries of Erie, Colorado. 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.

The rifle was initially developed over a period of five months and was planned to replace the M16 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, owing to a focus on military projects.

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."

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.

The ACR is part of the Individual Carbine competition to replace the M4.

History Edit

The original Magpul Masada design represented a combination of several recent rifle designs, incorporating what was considered by its designers to be the best features of each in a single, lightweight, modular rifle platform.[8] 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/AR-15 (trigger pack), and the M16 (barrel, fire control group) were present.

The rifle also included 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. Just prior to the deal with Bushmaster, Magpul made additional changes to their design—the most obvious of these was 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 had on several occasions mentioned that depending on the barrel length of the weapon, the rate of fire was estimated to be in the range of 600–800 rpm (this is an estimate; specifics have not yet been verified). The weapon's caliber could easily be changed by replacing the bolt head, magazine and barrel.

In January 2008, the design of the Magpul Masada was licensed to Bushmaster Firearms International and the production version of the Masada became known as the Bushmaster ACR.
