Yuna Drop In Kit

The Yuna remix FRK is a self-contained drop-in fire control assembly designed for straightforward installation in compatible platforms. The housing is manufactured from 4140 steel for strength and durability, and includes a dual-leg activator design, a lever-retention feature intended to prevent the lever from dropping beneath the hammer during operation, and an ambidextrous three-position safety selector.

Installation is designed to require minimal disassembly. The upper receiver is opened by removing the rear takedown pin, the drop-in assembly is installed into the lower receiver, and the firearm is then reassembled. No permanent modifications, cutting, grinding, or material removal are required for installation on compatible receivers with a low cut shelf/M16 shelf such as;

-Anderson

-Palmetto state armory

-Remington

-ATI

-Aero 

-Bushmaster

-Radian

The selector provides three distinct positions:

• Safe
• Semi-Automatic
• Fast Semi-Automatic

The kit is engineered as a self-contained assembly to simplify installation and removal while maintaining consistent component alignment. All primary components are manufactured from 4140 steel and the lever is AR500
