AR-15 – ZEROED Lower Parts Kit – Ambi Controls
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The CMMG ZEROED lower parts kit is a more complete AR-15 lower receiver kit with upgraded control pieces, including ambidextrous controls and CMMG ZEROED components. This is the stronger choice when the build deserves better than the bare-bones bag of sadness.
Fitment
- Fits AR-15 lower receiver builds.
- Built around CMMG ZEROED lower control components.
What it does
This kit provides the key lower receiver controls, springs, pins, trigger components, pistol grip, and ambidextrous-focused upgrades needed to complete an AR-15 lower.
Why it’s worth it
The value is in getting a fuller kit with useful control upgrades already included. The ambi safety, ambi magazine catch, extended bolt catch, extended magazine release button, and HD pivot/takedown pins make the lower feel more intentional instead of slapped together from whatever was hiding in a parts bin.
