The Desert Tech WLVRN, pronounced "Wolverine", is the successor to the company's MDRx bullpup multi caliber weapon system.
[3] The WLVRN was initially launched in three color options: Black, Flat Dark Earth (FDE), and Tungsten.
The WLVRN's specific improvements over the MDRx include a machined Trunnion (for retaining the Barrel Assembly) into the Receiver, new Barrel/barrel extension design, replaceable feed-ramps, new bolt carrier design, updated charging handles (from the 2023 MDRX updates), a new mag release system, new enhanced sealing gas block design with the pic rail removed, new chassis (to fill the hole where the pic rail was removed), removal of the forward eject system resulting in less gas required to cycle the action.
[4][5] On January 19 2024, A stand alone conversion kit the "MICRON" for the WLVRN was announced, featuring an extremely short handguard to minimize the rifle's overall length.
[6] On the MDRX live Q/A, Desert tech acknowledged the problem and is implementing a design change to correct the defect.
