Design

Magpul Masada, the design origin of the Bushmaster ACR
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. [4] 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 AR-18 is an Assault rifle chambered for 556x45mm NATO Ammunition. Gas-operation is a system of operation used to provide energy to operate Autoloading firearms The SOF Combat Assault Rifle, or SCAR, is a modular Rifle made by Fabrique Nationale de Herstal (FNH for the U The G36 is a German 556 mm Assault rifle, designed in the early 1990s by Heckler & Koch GmbH (H&K and accepted into service with the The XM8 is a developmental US military designation and project name for a lightweight Assault rifle system that was under development by the United States Army A polymer is a large Molecule ( Macromolecule) composed of repeating Structural units typically connected by Covalent Chemical bonds AR-15 (for Ar malite model 15, often mistaken for A utomatic R ifle is the common name for the widely-owned semi-automatic M16 (more formally United States Rifle II Caliber 556 mm M16) is the U A barrel or cask is a hollow cylindrical container traditionally made of Wood Staves and bound with Iron Hoops The The rifle also includes several features developed by Magpul, 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. [5] 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). The G3 is a 762 mm Automatic rifle developed in the 1950s by the German armament manufacturer Heckler & Koch GmbH (HK in collaboration The MP5 is a 9 mm Submachine gun of German design developed in the 1960s by a team of engineers from the West German arms manufacturer Experts from Magpul Industries have on several occasions mentioned that depending on the barrel length of the weapon, that the Rate of Fire is estimated to be in the range of 600-800 rpm (This is but an estimate however, 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 is STANAG 4179-compatible, as it will readily fit any STANAG magazine firearm, including the M16 rifle family. A STANAG magazine is a type of detachable firearm magazine standardized by NATO in October 1980 M16 (more formally United States Rifle II Caliber 556 mm M16) is the U [6] The Bushmaster ACR's modular construction even allows the user to fire the 7.62x39mm round depending on the choice of parts. The Soviet 762x39mm rifle cartridge was designed during World War II and first used in the SKS Carbine.

Miscellaneaous

The rifle was originally named after the Siege of Masada. Masada ( Hebrew מצדה pronounced Metzada, from מצודה metzuda, "fortress" is the name for a site of ancient Palaces and 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. "[8] When production rights were signed with Bushmaster, the Masada name was dropped from the product.
