The Remington ACR can Mount Different Types of Scopes.
The Remington Adaptive Combat Rifle (ACR) is an infantry assault weapon exclusively designed for military use. A modified version called the Bushmaster ACR is sold to law enforcement agencies and civilians. Originally developed as the Magpul Industries Masada, the rifle's most notable feature is its modular deign. It can fit either an 18-inch barrel for long-range shooting or change the gun barrel into a shorter 14.5-inch barrel similar to an AK-47 for shooting in smaller spaces.
Removable Iron Sight
The Remington ACR rifle, similar to the Bushmaster ACR, is fitted with a removable iron sight. Called the MBUS (Magpul Back-Up Sight), it is a low-cost, folding back-up iron sight with elements situated at both the front and rear part of the rifle. The Remington ACR's iron sight is spring-loaded and can be easily flipped open from either the left or right side for ambidextrous use, or by pressing the top. An iron sight by definition is a system of aligned markers used to assist the shooter in aiming the rifle without the need of having an optical sight such as a scope, which the Remington ACR can also support. The iron sight works by providing horizontal and vertical reference points, allowing shooters to align the rifle to their line of sight. It has both a front and rear sight to guide the shooter in aligning the shot. The iron sight on the Remington ACR can be removed to accommodate other sights such as a telescopic sight or a night vision sight.
Telescopic Sight
The Remington ACR also has the capability to mount a telescopic sight, commonly called a scope, onto the rifle. It gives the shooter additional accuracy by enabling focus on both the scope's crosshairs and the target at the same time. The lenses of the scope provide telescopic magnification, which makes the target clearer even from a far distance. It also allows the target to stand out against the background, making for a more accurate shot. However, the main disadvantage of magnification is that the area on either side of the target is obscured by the scope. As a result, the higher the magnification, the narrower the field of view becomes and the more area is hidden. A scope is an expensive add-on to any rifle and often requires additional training to enable the shooter to align the scope properly.
Night Vision Sight
The Remington ACR also supports night vision devices for tactical operations in the dark or at night. A night vision device gathers the current ambient light, which can be starlight, moonlight or infrared light, through the front lens. The existing light is made up of photons converted to electrons the moment they penetrate the tube of the night vision sight. The electrons are then amplified through an electrical and chemical process and hurled against a phosphorus screen, thus changing the amplified electrons back into visible light, which is a clear, green-hued amplified re-creation of the scene which the shooter can see through the eyepiece. The main factors affecting the effectiveness of a nigh vision device are distance and ambient light availability.
