BROWNELLS BUNDLES BRN-180® GEN 3 UPPER & LOWER BUNDLE

BRN-180 Gen 3 + Your Choice of Lower – Modern Performance, Built Your Way

The BRN-180 Gen 3 upper brings a modern twist to a classic design with a monolithic, side-charging upper, a robust short-stroke gas piston system, and a bufferless recoil assembly—perfect for folding stock builds and suppressed setups. With enhanced features like a tuned ejection system and tool-free adjustable gas settings, it’s made for smooth, reliable performance in any environment.

Pair it with your choice of two purpose-built lowers:

• BRN-180M Lower: A streamlined, ambidextrous lower receiver designed specifically for the BRN-180. Features a full-width rear shelf and integrated 1913 rail for folding stock compatibility—lightweight, clean, and ready to go.

• ADM UIC-180 Lower: Built by American Defense Manufacturing, this premium billet lower combines ADM’s fully ambidextrous control suite with geometry tailored for the BRN-180’s monolithic upper. It’s the choice for those who want top-tier fit, finish, and function.
