AR-15 – Lower Parts Kit – Without Grip/Fire Control Group
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The CMC Triggers AR-15 Lower Parts Kit gives you the core lower receiver parts needed for a compatible AR-15 build while leaving out the fire control group and pistol grip. That makes it useful when you already plan to run an upgraded trigger and your own grip.
Fitment
- Fits compatible AR-15 lower receivers.
- Built with mil-spec lower receiver components.
- Intended for builds using a separate trigger/fire control group and pistol grip.
Does NOT fit
- Does not include fire control group.
- Does not include pistol grip.
- Does not replace every part needed for a fully complete lower if you do not already have a trigger and grip.
What it does
This kit supplies the small lower receiver components needed around the bolt catch, magazine release, safety, buffer retainer, trigger guard, and takedown pin assemblies.
Why it’s worth it
This kit makes sense when the trigger and grip are already being upgraded. You are not paying for throwaway parts, and the build stays cleaner from the start. Practical gear, no fluff.
