Frequently Asked Questions
Will the CMMG ZEROED LPK fit any AR-15 lower receiver?
Yes — the CMMG ZEROED Lower Parts Kit is built to mil-spec dimensions, making it compatible with the vast majority of AR-15 lower receivers on the market. Whether your lower is forged, billet, or polymer, as long as it conforms to standard mil-spec tolerances, this kit will fit and function correctly.
Does this kit include a pistol grip and buffer components?
No — the ZEROED LPK covers the internal fire control and lower hardware components but does not include a pistol grip, buffer tube, buffer, buffer spring, or stock. You will need to source those components separately to complete your lower build.
Is the trigger in this kit suitable for use as-is, or should I upgrade it later?
The mil-spec trigger group included in the CMMG ZEROED LPK is fully functional and reliable for general range use, training, and home defense. Many shooters use mil-spec triggers long-term without issue. However, if you're building a precision or competition rifle, you may eventually want to upgrade to an enhanced drop-in trigger group for a lighter pull and crisper break.
