Description

Inspired by the Armalite® AR-180 of the 1960s. The Ranger MK-19 RONIN edition shares a large chunk of components with the BRN-180® piston system but introduces key features to improve reliability and usability in a short configuration.

With an entirely self-contained recoil system, the Ranger MK-19 RONIN rifle deos not require a buffer tube. This allows for easy compatibility with folding stocks and rear picatinny adapters. Recoil guide rods and buffer easily remove from the rear when removing the upper receiver from the lower. Bolt and carrier easily slide out when removing the charging handle at the rear. Large ejection port allows for ease of access for cleaning.

Lightweight barrel profile sits inside the slim handguard, making for an extremely lightweight package, even with the piston driven system. Top picatinny rail sits extremely low compared to other piston systems, allowing for broad compatibility with common AR-15 height optic mounts and sights. Barrels feature a 223 Wylde chamber to function with the broadest spectrum of 223 Remington and 5.56x45mm NATO ammunition

Free float MLOK handguard is free floated, and can easily be removed with one large screw located on the bottom of the receiver. This screw engages the rear of the barrel, pulling the handguard tight up against the receiver. Easily removed handguard allows for quick access to the gas system.

Gas plug has two settings:

U = Unsuppressed

S = Suppressed
