The Modular Rifle - Caseless is an American mockup concept bullpup assault rifle.
The MR-C was designed by Crye Associates as a mockup of an assault rifle. It was intended to be sold to the United States Army as a next-generation weapon which fires next-generation ammunition; the rifle is simply labelled as a "Modular Caseless Carbine Mock-Up" on the Crye Associates website. The weapon has not actually been developed, even in prototype form; it has never appeared in any OICW-related or Army-related contests featuring assault rifles.
If produced, the MR-C would use 6.8mm caseless ammunition in a bullpup layout. The weapon has a 40mm underbarrel grenade launcher known as the AGL.
The weapon uses a 6.8mm Caseless bullet.
- The MR-C is very widely known for its appearances in Tom Clancy's Ghost Recon: Advanced Warfighter and other Ghost Recon video games. In fact, most information about the MR-C is taken from video games and should not be taken as fact.
