Meridian Defense Corp Pestilence-74 Rifle - 5.45x39mm 14.5" Pinned AAC 51T

Meridian Defense Corp Pestilence-74 Rifle - 5.45x39mm 14.5" Pinned AAC 51T

The first in Meridian Defense Corp’s exclusive Four Horsemen of the Apocalypse Series—a rifle that fuses old-world AK aesthetics with modern performance engineering. Built from an original Polish 5.45x39 military parts kit, this rifle is riveted into a 1mm fully heat-treated MDC-5.45 stamped receiver, delivering unmatched durability and tighter tolerances for superior reliability.

At its core is a 4150 CMV black nitrided barrel with a 1:7 twist, pinned and welded to a legal 16.1" overall length, ensuring compliance without sacrificing maneuverability. The MDC-BD2-51T muzzle device and MDC-FSB combo sight/gas block are CNC-machined for precision and integrated gas control. The adjustable low-profile gas block allows fine-tuning for suppressed or unsuppressed use, preventing over-gassing and ensuring smooth cycling.

Topped with an Ultimak M1913 Picatinny gas tube and side rail mount, the Pestilence is optics-ready and modular. The custom-refinished “Apocalypse” wood furniture, paired with a battleworn finish, gives this rifle a hauntingly beautiful aesthetic. Finished with a US PALM AK grip, MDC performance trigger, and three Magpul polymer magazines branded with the Octopus logo, this rifle is as functional as it is collectible.
