Prototype Rifle

The Prototype Rifle is an infantry weapon featured in Mercenaries: Playground of Destruction and Mercenaries 2: World in Flames.

Overview
The weapon is scoped, and holds 100 rounds per magazine, making it a three-way combination of the Carbine, the Sniper Rifle, and the Light Machine Gun.

The Prototype Rifle is superior to the Carbine in many ways, such as the larger magazine size, the accuracy (although not by too much), and most importantly, the scope. Though the scope is incapable of being used with consistent fire, it can be used to snipe enemies, as firing a single shot is akin to the Sniper Rifle - both in range and accuracy. However, do not rely on this weapon for long distances; although it is fairly accurate, it does not compare anywhere near as much as the other sniper rifles.

Locations

 * The supply drop containing the, called the "Advanced Supply Drop," is unlocked by collecting 40 of the 100 blueprints scattered around the maps.
 * The Prototype Rifle can be found with only a few types of soldiers; members of the ROKA 707th Commando Unit and some regular SKU soldiers. Some of the SKU soldiers guarding the SK Officer during Omertà carry this.
 * General Choi Song uses it as his personal weapon.

Real life
The is heavily based on the Heckler and Koch G36. It may also be based on the MG36, a LSW variant of the G36 with a heavier barrel, meant to be used with drum magazines for suppresive fire. This weapon never made it past prototype phase, possibly explaining the "Prototype Rifle" moniker.

Trivia

 * There is no realistic way for 100 rounds to fit in the magazine portrayed in-game, which holds 30 maximum. According to the description on the Merchant of Menace, the rifle is equipped with a drum magazine, though this is not shown on the in-game model, it does explain the ammo count.
 * The gun that the Prototype Rifle is based on - the G36 - is well past prototype stage. Alternatively, it might be a fictional North Korean knockoff of the G36, due to the isolation of the country. It's also possible that the developers mistook it for the prototype XM8 (at the time) that would later appear in Mercenaries 2 as the Combat Rifle.
