MBR-308

The is a battle rifle manufactured by Bullpup Rifle Systems co., serving as a compact bullpup rifle using the lethal 7.62mm round in a compact, effective package.
== History ==
The MBR-308 was developed since 2006 by retired Panamoan Army Sgt. August Grayson due to the demand for a short 7.62mm rifle for use in combat, without any penalties to movement or maneuverability, along with being able to mount optics or other attachments. The first prototypes of the rifle were revealed in 2008.]
The rifle continued development until 2010 when the fourth generation final models were produced. The fourth generation rifle kits have been produced since 2012 and are currently being marketed by Bullpup Rifle Systems co. since 2012.
== Design ==
The is a drop-in chassis for any MN14 rifle platform. A number of parts on the MN14 need to be removed before the weapon can be dropped into the chassis. The weapon is ambidextrous; the charging handle can be placed on either side of the weapon, making it user friendly to both left and right handed shooters. The chassis is available in a wide variety of configurations for use in different situations.
The entire chassis is constructed from Nevium alloys gathered from Skagua V4MK, and the majority of it's metallic components, including the rifled barrel. The pistol grip is made from extremely durable Polyethylene reinforced resin, it had an advanced rifling twist rate to accommodate for high accuracy and stopping power without suffering from the degraded ballistic performance from short barrels, but the effective range is fairly average, and largely similar to mid sized 5.56mm SDC rifles.
