AR-15 – Lower Parts Kit – Without Grip/Fire Control Group
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The CMMG AR-15 gun builder’s lower parts kit gives you the common lower receiver parts needed for a build while leaving out the parts many builders already plan to upgrade: the pistol grip and fire control group.
Fitment
- Fits standard AR-15 lower receiver builds.
- Intended for builders using their own trigger/fire control group and pistol grip.
Does NOT fit
- Does not include pistol grip.
- Does not include fire control group.
- Does not include trigger guard where noted by CMMG/retailer listings.
What it does
This kit fills in the small lower receiver parts needed to complete a standard AR-15 lower while letting you choose your own trigger and grip. That makes it useful for builds where the basic mil-spec trigger was never going to stay anyway.
Why it’s worth it
This is a smarter kit when you already know you’re using an upgraded trigger and grip. You avoid paying for parts that go straight into the junk drawer of shame.
